The social distancing and sheltering in place mandated because of the COVID-19 pandemic are keeping parents and kids out of their doctors’ offices, and that has prompted a steep decline in recommended routine vaccinations for U.S. children, according to Centers for Disease Control and Prevention researchers.

Pediatric vaccinations dropped sharply after the national emergency was declared on March 13, suggesting that some children may be at increased risk for other serious infectious diseases, such as measles.

The researchers compared weekly orders for federally funded vaccines from Jan. 6 to April 19, 2020, with those during the same period in 2019.

They noted that, by the end of the study period, there was a cumulative COVID-19–related decline of 2.5 million doses in orders for routine noninfluenza pediatric childhood vaccines recommended by the Advisory Committee on Immunization Practices, as well as a cumulative decline in orders of 250,000 doses of measles vaccines.

Although the overall decrease in vaccinations during the study period was larger, according to CDC spokesperson Richard Quartarone, the above figures represent declines clearly associated with the pandemic.

The weekly number of measles vaccines ordered for children aged 24 months or older fell dramatically to about 500 during the week beginning March 16, 2020, and fell further to approximately 250 during the week beginning March 23. It stayed at that level until the week beginning April 13. By comparison, more than 2,500 were ordered during the week starting March 2, before the emergency was declared.

The decline was notably less for children younger than 2 years. For those children, orders dropped to about 750 during the week starting March 23 and climbed slightly for 3 weeks. By comparison, during the week of March 2, about 2,000 vaccines were ordered.

The findings, which were published in the CDC’s Morbidity and Mortality Weekly Report, stem from an analysis of ordering data from the federal Vaccines for Children (VFC) Program, as well as from vaccine administration data from the CDC’s Vaccine Tracking System and the collaborative Vaccine Safety Datalink (VSD).

The VFC provides federally purchased vaccines at no cost to about half of persons aged 18 years or younger. The VSD collaborates on vaccine coverage with the CDC’s Immunization Safety Office and eight large health care organizations across the country. Vaccination coverage is the usual metric for assessing vaccine usage; providers’ orders and the number of doses administered are two proxy measures, the authors explained.

“The substantial reduction in VFC-funded pediatric vaccine ordering after the COVID-19 emergency declaration is consistent with changes in vaccine administration among children in the VSD population receiving care through eight large U.S. health care organizations,” wrote Jeanne M. Santoli, MD, and colleagues, of the immunization services division at the National Center for Immunization and Respiratory Diseases. “The smaller decline in measles-containing vaccine administration among children aged ≤24 months suggests that system-level strategies to prioritize well child care and immunization for this age group are being implemented.”

Dr. Santoli, who is an Atlanta-based pediatrician, and associates stressed the importance of maintaining regular vaccinations during the pandemic. “The identified declines in routine pediatric vaccine ordering and doses administered might indicate that U.S. children and their communities face increased risks for outbreaks of vaccine-preventable diseases,” they wrote. “Parental concerns about potentially exposing their children to COVID-19 during well child visits might contribute to the declines observed.” Parents should therefore be reminded of the necessity of protecting their children against vaccine-preventable diseases.

In 2019, a Gallup survey reported that overall support for vaccination continued to decline in the United States.

The researchers predicted that, as social distancing relaxes, unvaccinated children will be more susceptible to other serious diseases. “In response, continued coordinated efforts between health care providers and public health officials at the local, state, and federal levels will be necessary to achieve rapid catch-up vaccination,” they concluded.

The authors disclosed no relevant financial relationships.

As the COVID-19 pandemic spreads over the country, nearly half (48%) of US healthcare facilities — of various types and sizes — are already or almost out of respirators for treating patients, according to the results of a national online survey of infection prevention professionals.

Conducted during March 23-25 by the Association for Professionals in Infection Control and Epidemiology (APIC), the survey asked APIC’s 11,922 US-based infection preventionist members to rank their facilities’ supply of personal protective equipment (PPE) and key items, such as hand sanitizer and cleaning products, on a 5-point scale from having “plenty” to “none.”

Overall, 1,140 (9.6%) infection preventionists responded. Almost 70% of respondents represented a healthcare system rather than a single facility, and facilities ranged from hospitals (42.7%) to ambulatory care (17.4%) and dialysis (2.7%). The centers, from all 50 states and Washington, D.C., ranged in size from those with 1 to 50 beds to those with more than 300 beds.

Of the respondents, 233 (20.4%) reported their facilities have no protective respirators and 317 (27.8%) said they were almost out of the devices, which are needed to protect healthcare workers managing patients with COVID-19 and different infectious diseases.

The survey was posted Friday on the APIC website.

Other findings from the survey include:

• Nearly half of respondents (49.2%) said their centers lack sufficient enough face shields, with 36.5% reporting being almost out and 12.6% reporting being completely out.
• Approximately one third (31.7%) of respondents reported being completely or nearly out of face masks.
• Even simple hand sanitizer is in short supply at more than 1 in 4 facilities surveyed; 25.6% of respondents said they are almost out and 2.6% are completely out.
• Nearly 30% of respondents reported accessing supplemental PPE through state or local resources, while 24.6% said they accepted private donations of supplies.
• Fewer than one-third (31.5%) said they had sufficient gowns.
• About 28% said they were almost out of protective respirators, while 20.5% said they have none.
• Only 12.3% said they have received supplies from federal resources, including the Strategic National Stockpile, which is controlled by the Department of Health and Human Services.
• 17.2% of respondents reported resorting to DIY measures such as sewing their own masks.

In terms of staffing resources, 67% of respondents said their center has only one (or fewer) full-time–equivalent infection preventionist on staff to develop protocols for managing COVID-19. That is not surprising given the general underresourcing of infection control programs, the survey compilers said.

“Hospitals and health facilities with fewer than one full-time person on staff to direct infection prevention activities may have been disadvantaged even before the COVID-19 pandemic,” said APIC president Connie Steed, MSN, RN, in a related news release.

On a more positive note, about two thirds of facilities said they have sufficient supplies of gloves (63.4%) and hand washing soap (67.1%).

“I am concerned that many facilities will not be able to protect healthcare workers and patients from not only COVID-19, but also MRSA, C diff., and other antibiotic-resistant infections,” Steed said.

At some centers, however, the situation is not so grim — yet. The large Harris Health System in Houston has enough PPE on hand to support all infection prevention protocols in place, according to Bryan McLeod, director of corporate communications. “The PPE inventory varies from a few weeks to well over a month depending on the specific item,” McLeod told Medscape Medical News. “But everything is dependent on the utilization rate, which can vary with patient volume. Our concern is long-term resupply while demand is peaking around the world, and we continue to pursue all avenues to secure resupply.”

Above all, Steed emphasizes healthcare workers’ need for clarity. “They need to know when exactly they can expect desperately needed supplies to arrive so they don’t have to turn to unproven crisis methods for PPE,” she said. “There have been grim reports from health officials about the supply shortage for weeks and we’re not getting any answers. This is unacceptable.”

APIC is urging the federal government for immediate activation of the Cold War–era Defense Production Act and any other available means to quickly manufacture vital supplies to protect healthcare workers treating the escalating numbers of COVID-19 patients.

In the meantime, frontline healthcare workers are scouring the Internet for suppliers and begging online for donations of masks.

APIC notes that the COVID-19 pandemic is compounded by this year’s particularly severe influenza season, which had already led overcrowded healthcare facilities.

Hospital-related infections have been widely reported during the ongoing coronavirus outbreak, with healthcare professionals bearing a disproportionate risk. However, a proactive response in Hong Kong’s public hospital system appears to have bucked this trend and successfully protected both patients and staff from SARS-CoV-2, according to a study published online today in Infection Control & Hospital Epidemiology.

During the first 42 days of the outbreak, the 43 hospitals in the network tested 1275 suspected cases and treated 42 patients with confirmed COVID-19, the disease caused by SARS-CoV-2 infection. Yet, there were no nosocomial infections or infections among healthcare personnel, report Vincent C.C. Cheng, MD, FRCPath, the hospital’s infection control officer, and colleagues.

Cheng and colleagues note that 11 out of 413 healthcare workers who treat patients with confirmed infections had unprotected exposure and were in quarantine for 14 days, but none became ill.

In comparison, they note, the 2003 SARS outbreak saw almost 60% of nosocomial cases occurring in healthcare workers.

Proactive bundle

The Hong Kong success story may be due to a stepped-up proactive bundle of measures that included enhanced laboratory surveillance, early airborne infection isolation, and rapid-turnaround molecular diagnostics. Other strategies included staff forums and one-on-one discussions about infection control, employee training in protective equipment use, hand-hygiene compliance enforcement, and contact tracing for workers with unprotected exposure.

In addition, surgical masks were provided for all healthcare workers, patients, and visitors to clinical areas, a practice previously associated with reduced in-hospital transmission during influenza outbreaks, the authors note.

Hospitals also mandated use of personal protective equipment (PPE) for aerosol-generating procedures (AGPs), such as endotracheal intubation, open suctioning, and high-flow oxygen use, as AGPs had been linked to nosocomial transmission to healthcare workers during the 2003 SARS outbreak.

The infection control measures, which were part of a preparedness plan developed after the SARS outbreak, were initiated on December 31, when the first reports of a cluster of infections came from Wuhan, China.

As the outbreak evolved, the Hong Kong hospitals quickly widened the epidemiologic criteria for screening, from initially including only those who had been to a wet market in Wuhan within 14 days of symptom onset, to eventually including anyone who had been to Hubei province, been in a medical facility in mainland China, or in contact with a known case.  

All suspected cases were sent to an airborne-infection isolation room (AIIR) or a ward with at least a meter of space between patients.

“Appropriate hospital infection control measures could prevent nosocomial transmission of SARS-CoV-2,” the authors write. “Vigilance in hand hygiene practice, wearing of surgical mask in the hospital, and appropriate use of PPE in patient care, especially [when] performing AGPs, are the key infection control measures to prevent nosocomial transmission of SARS-CoV-2 even before the availability of effective antiviral agents and vaccine.”

Asked for his perspective on the report, Aaron E. Glatt, MD, chairman of the department of medicine and chief of infectious diseases at Mount Sinai South Nassau in Oceanside, New York, said that apart from the widespread issuing of surgical masks to workers, patients, and visitors, the measures taken in Hong Kong are not different from standard infection-control practices in American hospitals. Glatt, who is also a hospital epidemiologist, said it was unclear how much impact the masks would have.

“Although the infection control was impressive, I don’t see any evidence of a difference in care,” he told Medscape Medical News.

Could zero infection transmission be achieved in the more far-flung and variable settings of hospitals across the United States? “The ability to get zero transmission is only possible if people adhere to the strictest infection-control guidelines,” Glatt said. “That is clearly the goal, and it will take time to see if our existing strict guidelines are sufficient to maintain zero or close to zero contamination and transmission rates in our hospitals.”

Rather than looking to change US practices, he stressed adherence to widely established tenets of care. “It’s critically important to keep paying close attention to the basics, to the simple blocking and tackling, and to identify which patients are at risk, and therefore, when workers need protective equipment,” he said.

“Follow the recommended standards,” continued Glatt, who is also a spokesperson for the Infectious Diseases Society of America and did not participate in this study.

In a finding from an ancillary pilot experiment, the Hong Kong researchers found exhaled air from a patient with a moderate coronavirus load showed no evidence of the virus, whether the patient was breathing normally or heavily, speaking, or coughing. And spot tests around the room detected the virus in just one location.

“We may not be able to make a definite conclusion based on the analysis of a single patient,” the authors write. “However, it may help to reassure our staff that the exhaled air may be rapidly diluted inside the AIIR with 12 air changes per hour, or probably the SARS-CoV-2 may not be predominantly transmitted by [the] airborne route.”

However, a recent Singapore study showed widespread environmental contamination by SARS-CoV-2 through respiratory droplets and fecal shedding, underlining the need for strict adherence to environmental and hand hygiene. Post-cleaning samples tested negative, suggesting that standard decontamination practices are effective. 

This work was partly supported by the Consultancy Service for Enhancing Laboratory Surveillance of Emerging Infectious Diseases of the Department of Health, Hong Kong Special Administrative Region; and the Collaborative Innovation Center for Diagnosis and Treatment of Infectious Diseases, Ministry of Education of China. The authors and Glatt have disclosed no relevant financial relationships.

Could zero infection transmission be achieved in the more far-flung and variable settings of hospitals across the United States? “The ability to get zero transmission is only possible if people adhere to the strictest infection-control guidelines,” Glatt said. “That is clearly the goal, and it will take time to see if our existing strict guidelines are sufficient to maintain zero or close to zero contamination and transmission rates in our hospitals.”

Rather than looking to change US practices, he stressed adherence to widely established tenets of care. “It’s critically important to keep paying close attention to the basics, to the simple blocking and tackling, and to identify which patients are at risk, and therefore, when workers need protective equipment,” he said.

“Follow the recommended standards,” continued Glatt, who is also a spokesperson for the Infectious Diseases Society of America and did not participate in this study.

In a finding from an ancillary pilot experiment, the Hong Kong researchers found exhaled air from a patient with a moderate coronavirus load showed no evidence of the virus, whether the patient was breathing normally or heavily, speaking, or coughing. And spot tests around the room detected the virus in just one location.

“We may not be able to make a definite conclusion based on the analysis of a single patient,” the authors write. “However, it may help to reassure our staff that the exhaled air may be rapidly diluted inside the AIIR with 12 air changes per hour, or probably the SARS-CoV-2 may not be predominantly transmitted by [the] airborne route.”

However, a recent Singapore study showed widespread environmental contamination by SARS-CoV-2 through respiratory droplets and fecal shedding, underlining the need for strict adherence to environmental and hand hygiene. Post-cleaning samples tested negative, suggesting that standard decontamination practices are effective.

Hospital-related infections have been widely reported during the ongoing coronavirus outbreak, with healthcare professionals bearing a disproportionate risk. However, a proactive response in Hong Kong’s public hospital system appears to have bucked this trend and successfully protected both patients and staff from SARS-CoV-2, according to a study published online today in Infection Control & Hospital Epidemiology.

During the first 42 days of the outbreak, the 43 hospitals in the network tested 1275 suspected cases and treated 42 patients with confirmed COVID-19, the disease caused by SARS-CoV-2 infection. Yet, there were no nosocomial infections or infections among healthcare personnel, report Vincent C.C. Cheng, MD, FRCPath, the hospital’s infection control officer, and colleagues.

Cheng and colleagues note that 11 out of 413 healthcare workers who treat patients with confirmed infections had unprotected exposure and were in quarantine for 14 days, but none became ill.

In comparison, they note, the 2003 SARS outbreak saw almost 60% of nosocomial cases occurring in healthcare workers.

Proactive bundle

The Hong Kong success story may be due to a stepped-up proactive bundle of measures that included enhanced laboratory surveillance, early airborne infection isolation, and rapid-turnaround molecular diagnostics. Other strategies included staff forums and one-on-one discussions about infection control, employee training in protective equipment use, hand-hygiene compliance enforcement, and contact tracing for workers with unprotected exposure.

In addition, surgical masks were provided for all healthcare workers, patients, and visitors to clinical areas, a practice previously associated with reduced in-hospital transmission during influenza outbreaks, the authors note.

Hospitals also mandated use of personal protective equipment (PPE) for aerosol-generating procedures (AGPs), such as endotracheal intubation, open suctioning, and high-flow oxygen use, as AGPs had been linked to nosocomial transmission to healthcare workers during the 2003 SARS outbreak.

The infection control measures, which were part of a preparedness plan developed after the SARS outbreak, were initiated on December 31, when the first reports of a cluster of infections came from Wuhan, China.

As the outbreak evolved, the Hong Kong hospitals quickly widened the epidemiologic criteria for screening, from initially including only those who had been to a wet market in Wuhan within 14 days of symptom onset, to eventually including anyone who had been to Hubei province, been in a medical facility in mainland China, or in contact with a known case.  

All suspected cases were sent to an airborne-infection isolation room (AIIR) or a ward with at least a meter of space between patients.

“Appropriate hospital infection control measures could prevent nosocomial transmission of SARS-CoV-2,” the authors write. “Vigilance in hand hygiene practice, wearing of surgical mask in the hospital, and appropriate use of PPE in patient care, especially [when] performing AGPs, are the key infection control measures to prevent nosocomial transmission of SARS-CoV-2 even before the availability of effective antiviral agents and vaccine.”

Asked for his perspective on the report, Aaron E. Glatt, MD, chairman of the department of medicine and chief of infectious diseases at Mount Sinai South Nassau in Oceanside, New York, said that apart from the widespread issuing of surgical masks to workers, patients, and visitors, the measures taken in Hong Kong are not different from standard infection-control practices in American hospitals. Glatt, who is also a hospital epidemiologist, said it was unclear how much impact the masks would have.

“Although the infection control was impressive, I don’t see any evidence of a difference in care,” he told Medscape Medical News.

Could zero infection transmission be achieved in the more far-flung and variable settings of hospitals across the United States? “The ability to get zero transmission is only possible if people adhere to the strictest infection-control guidelines,” Glatt said. “That is clearly the goal, and it will take time to see if our existing strict guidelines are sufficient to maintain zero or close to zero contamination and transmission rates in our hospitals.”

The Centers for Disease Control and Prevention has released an updated schedule for adult vaccines. The update includes changes regarding the administration of several vaccines, including those for influenza, human papillomavirus (HPV), hepatitis A and B, and meningitis B, as well as the pneumococcal 13-valent conjugate (PCV13) vaccine.

The schedule, revised annually by the Advisory Committee on Immunization Practices (ACIP) of the CDC, was simultaneously published online February 3, 2020, in the Annals of Internal Medicine and on the CDC website.

Perhaps the change most likely to raise questions is that concerning the PCV13 vaccine. “Owing to a decline in prevalence of the types covered by the PCV13 vaccine, this is no longer routinely recommended for all persons age 65 and older,” senior author Mark Freedman, DVM, MPH, of the immunization services division at the National Center for Immunization and Respiratory Disease, said in an interview.

For purposes of shared clinical decision, however, it should be discussed with previously unvaccinated seniors who do not have risk factors, such as an immunocompromising condition, a cerebrospinal fluid leak, or a cochlear implant.

“But the circumstances for use of the vaccine are not always clear even based on the detailed list of considerations provided, because it’s impossible to think of every conceivable combination of risk factors,” Mr. Freedman added.

Possible beneficiaries of this vaccine are vulnerable elderly people living in nursing homes and long-term care facilities and those living in or traveling to settings in which the rate of pediatric PCV13 uptake is low or zero.

All adults in this age group should continue to receive a single dose of the pneumococcal 23-valent polysaccharide vaccine.*

HPV

The advisory committee now recommends catch-up immunization for women and men through age 26 years (the previous cutoff for men was 21). And in another new recommendation, the ACIP advises considering vaccination for some patients aged 27-45 years who have not been adequately vaccinated.

“Most people ages 27-45 do not need vaccination, but some may benefit,” Mr. Freedman said. “For example, somebody who’s been in a prior long-term monogamous relationship and suddenly finds himself with a new sexual partner.”

“That makes very good sense for older people who haven’t been vaccinated and might continue to be exposed to HPV,” Daniel M. Musher, MD, a professor of medicine at Baylor College of Medicine and an infectious diseases physician at the Michael E. DeBakey Veterans Affairs Medical Center, both in Houston, said in an interview.

Here again, the ACIP advises taking a shared decision-making approach, with clinicians discussing the merits of vaccination in this and other scenarios with patients according to the talking points outlined in the HPV section.

Influenza, hepatitis A and B

For the 2019-2020 influenza season, routine influenza vaccination is recommended for all persons aged 6 months or older who have no contraindications. Where more than one appropriate option is available, the ACIP does not recommend any product over another.

Routine hepatitis A vaccination is recommended for all persons aged 1 year or older who have HIV infection regardless of their level of immune suppression.

For hepatitis B, a new addition to the list of vulnerable patients who may possibly benefit from vaccination is pregnant women at risk for infection or an adverse infection-related pregnancy outcome. Whereas older formulations are safe, the ACIP does not recommend the HepB-CpG (Heplisav-B) vaccine during pregnancy, owing to the fact that safety data are lacking.

Meningitis B

Individuals aged 10 years or older who have complement deficiency, who use a complement inhibitor, who have asplenia, or who are microbiologists should receive a meningitis B booster dose 1 year following completion of a primary series. After that, they should receive booster doses every 2-3 years for as long they are at elevated risk.

Vaccination should be discussed with individuals aged 16-23 years even if they are not at increased risk for meningococcal disease. Persons aged 10 years or older whom public health authorities deem to be at increased risk during an outbreak should have a one-time booster dose if at least 1 year has elapsed since completion of a meningitis B primary series.

Td/Tdap, varicella

The ACIP now recommends that either the Td or Tdap vaccine be given in cases in which currently just the Td vaccine is recommended; that is, for the 10-year booster shot as well as for tetanus prophylaxis in wound management and the catch-up immunization schedule, including that for pregnant women.

Vaccination against varicella should be considered for HIV-infected individuals who are without evidence of varicella immunity and whose CD4 counts are at least 200 cells/mL.

Dr. Musher, who was not involved in drafting the recommendations, takes issue generally with the addition of shared clinical decision making on vaccination. “Shared decision making is a problem for anyone practicing medicine. It places a terrible burden [on] the doctors to discuss these options with patients at great length. Most patients want the doctor to make the decision.”

In his view, this approach makes little sense in the case of the PCV13 vaccine because the strains it covers have disappeared from the population through the widespread vaccination of children. “But discussions are important for some vaccines, such as the herpes zoster vaccine, since patients can have a terrible reaction to the first dose and refuse to have the second,” he said.

Some of these new recommendations were released in 2019 after ACIP members met to vote on them in February, June, and October.

As in previous years, the schedule has been streamlined for easier reference. Physicians are reminded to closely read the details in the vaccine notes, as these specify who needs what vaccine, when, and at what dose.

The ACIP develops its recommendations after reviewing vaccine-related data, including the data regarding the epidemiology and burden of the vaccine-preventable disease, vaccine effectiveness and safety, the quality of evidence, implementability, and the economics of immunization policy.

The authors have received grants and expense payments from public and not-for-profit institutions. One coauthor has received fees from ACI Clinical for data and safety monitoring in an immunization trial. Dr. Musher has disclosed no relevant financial relationships.
