COVID-19 vaccinations in people with HIV reflect general rates despite higher mortality risk, study says

Around the world, people with HIV show variations in COVID-19 vaccination rates similar to those seen in the general population, raising concerns because of their increased risk for morbidity and mortality from COVID-19 infection.

“To our knowledge, this analysis presents the first and largest investigation of vaccination rates among people with HIV,” reported the authors in research published in the Journal of Infectious Diseases.

The findings reflect data on nearly 7,000 people with HIV participating in the REPRIEVE clinical trial. As of July, COVID-19 vaccination rates ranged from a high of 71% in higher income regions to just 18% in sub-Saharan Africa and bottomed out at 0% in Haiti.

“This disparity in COVID-19 vaccination rates among people with HIV across income regions may increase morbidity from COVID-19 in the most vulnerable HIV populations,” the authors noted.

In general, people with HIV have been shown in recent research to have as much as 29% higher odds of morality from COVID-19 than the general population, and a 20% higher odds of hospitalization, hence their need for vaccination is especially pressing.

To understand the vaccination rates, the authors looked at data from the ongoing REPRIEVE trial, designed to investigate primary cardiovascular prevention worldwide among people with HIV. The trial includes data on COVID-19 vaccination status, providing a unique opportunity to capture those rates.

The study specifically included 6,952 people with HIV aged 40-75 years and on stable antiretroviral therapy (ART), without known cardiovascular disease, and a low to moderate atherosclerotic cardiovascular disease (ASCVD) risk.

The diverse participants with HIV were from 12 countries, including 66% who were people of color, as well as 32% women. Countries represented include Brazil (n = 1,042), Botswana (n = 273), Canada (n = 123), Haiti (n = 136), India (n = 469), Peru (n = 142), South Africa (n = 527), Spain (n = 198), Thailand (n = 582), Uganda (n = 175), United States (n = 3,162), and Zimbabwe (n = 123).

With vaccination defined as having received at least one vaccine shot, the overall cumulative COVID-19 vaccination rate in the study was 55% through July 2021.

By region, the highest cumulative rates were in the high-income countries of the United States and Canada (71%), followed by Latin America and the Caribbean (59%) – all consistent with the general population in these areas

Lower cumulative vaccination rates were observed in South Asia (49%), Southeast/East Asia (41%), and sub-Saharan Africa (18%), also reflecting the regional vaccination rates.

The United States had the highest country-specific COVID-19 vaccination rate of 72%, followed by Peru (69%) and Brazil (63%). Countries with the lowest vaccination rates were South Africa (18%), Uganda (3%), and Haiti (0%).

Of note, South Africa and Botswana have the largest share of deaths from HIV/AIDS, and both had very low COVID-19 vaccination rates in general, compared with high-income countries.

Overall, factors linked to the likelihood of being vaccinated included residing in the high-income U.S./Canada Global Burden of Disease superregion, as well as being White, male, older, having a higher body mass index (BMI), a higher ASCVD risk score, and longer duration of ART.

Participants’ decisions regarding COVID-19 vaccination in the study were made individually and were not based on any study-related recommendations or requirements, the authors noted.

Vaccination rates were higher among men than women in most regions, with the exception of sub-Saharan Africa. Vaccination rates were higher among Whites than Blacks in the U.S./Canada high-income region, with a high proportion of participants from the United States.

“It was surprising to us – and unfortunate – that in the high-income superregion vaccination rates were higher among individuals who identified as White than those who identified as Black and among men,” senior author Steven K. Grinspoon, MD, said in an interview.

“Given data for higher morbidity from COVID-19 among people of color with HIV, this disparity is likely to have significant public health implications,” said Dr. Grinspoon, a professor of medicine at Harvard Medical School and chief of the metabolism unit at Massachusetts General Hospital, both in Boston.

Newer data from the REPRIEVE study through October has shown continued steady increases in the cumulative vaccination rates in all regions, Dr. Grinspoon noted, with the largest increases in the Southeast/East Asia, South Asia, and sub-Saharan Africa, whereas a leveling off of rates was observed in the high-income regions.

Overall, “it is encouraging that rates among people with HIV are similar to and, in many regions, higher than the general population,” Dr. Grinspoon said.

However, with the data showing a higher risk for COVID-19 death in people with HIV, “it is critical that people with HIV, representing a vulnerable and immunocompromised population, be vaccinated for COVID-19,” Dr. Grinspoon said.

Commenting on the study, Monica Gandhi, MD, MPH, director of the Gladstone Center for AIDS Research at the University of California, San Francisco, agreed that “it is encouraging that these rates are as high as the general population, showing that there is not excess hesitancy among those living with HIV.”

Unlike other immunocompromised groups, people with HIV were not necessarily prioritized for vaccination, since antiretroviral therapy can reconstitute the immune system, “so I am not surprised the [vaccination] rates aren’t higher,” Dr. Gandhi, who was not involved with the study, said in an interview.

Nevertheless, “it is important that those with risk factors for more severe disease, such as higher BMI and higher cardiovascular disease, are prioritized for COVID-19 vaccination, [as] these are important groups in which to increase rates,” she said.

“The take-home message is that we have to increase our rates of vaccination in this critically important population,” Dr. Gandhi emphasized. “Global vaccine equity is paramount given that the burden of HIV infections remains in sub-Saharan Africa.”

The study received support from the National Institutes of Health and funding from Kowa Pharmaceuticals and Gilead Sciences. The authors and Dr. Gandhi disclosed no relevant financial relationships.
