Vaccination goals are possible with effort in the right places
The fact of below-target vaccination for HPV in the United States may be old news, but the current study offers new insights on HPV uptake, Amanda F. Dempsey, MD, PhD, of the University of Colorado at Denver, in Aurora, wrote in an accompanying editorial.
“A unique feature of this study is the ability of its researchers to study individuals over time, particularly at a national scope,” which yielded two key messages, she said.
The longitudinal examination of vaccination levels among birth cohorts showed that similar vaccination levels were achieved more quickly each year.
“For example, among the birth cohort from the year 2000, representing 17-year-olds at the time data were abstracted for the study, 40% vaccination coverage was achieved when this group was 14 years old. In contrast, among the birth cohort from the year 2005, representing 12-year-olds at the time of data abstraction, 40% vaccination coverage was reached at the age of 12,” Dr. Dempsey explained.
In addition, the study design allowed the researchers to model future vaccine coverage based on current trends, said Dr. Dempsey. “The authors estimate that, by the year 2022, the 2012 birth cohort will have reached 80% coverage for the first dose in the HPV vaccine series.”
Dr. Dempsey said she was surprised that the models did not support the hypothesis that school mandates for vaccination would increase coverage; however, there were few states in this category.
Although the findings were limited by the lack of data on uninsured children and those insured by Medicaid, the state-by-state results show that the achievement of national vaccination goals is possible, Dr. Dempsey said. In addition, the findings “warrant close consideration by policy makers and the medical community at large regarding vaccination policies and workforce,” she emphasized.The study received no outside funding. Dr. Chen had no financial conflicts to disclose. Several coauthors reported research grants to their institutions from pharmaceutical companies or being consultants to such companies. Dr. Dempsey disclosed serving on the advisory boards for Merck, Pfizer, and Sanofi Pasteur.
