A Multivariate Probit Regression of the Uptake of Adolescent Vaccines Among Racial/Ethnic Minority Adolescents Before and During the COVID-19 Pandemic.

Abstract

PURPOSE:

The uptake of adolescent vaccines has improved over the years. However, research of the effects of the COVID-19 pandemic on this uptake among racial/ethnic minority adolescents has been limited. This study was conducted to compare the probability of uptake of the human papillomavirus (HPV); tetanus, diphtheria, and acellular pertussis (Tdap); and quadrivalent meningococcal conjugate (MenACWY) vaccines among racial/ethnic minority adolescents ages 13-17 years in 2019, 2020, and 2021.

METHODS:

Using a cross-sectional design to examine data from the National Immunization Survey-Teen (2019-2021), multivariate probit regression was used to model variation in uptake of these three adolescent vaccines (n = 38,128). The outcome measures were HPV, Tdap, and MenACWY vaccine uptake.

RESULTS:

The probability of uptake of HPV vaccine was higher in 2020 (Coef = 0.09 [95% confidence interval (CI), 0.03-0.16]) and 2021 (Coef = 0.07 [95% CI, 0.00-0.15]) than in 2019. The probability of uptake of MenACWY vaccine was higher in 2020 (Coef = 0.08 [95% CI, 0.02-0.15]) than in 2019. The probability of uptake of recommended vaccines varied among racial/ethnic minorities with non-Hispanic Black adolescents exhibiting higher probability of uptake of HPV vaccine (Coef = 0.10 [95% CI, 0.01-0.19]) than Tdap vaccine. U.S. Census region and insurance status were associated with the uptake of all recommended vaccines.

DISCUSSION:

Progress in the uptake of these recommended vaccines may not have been interrupted by the COVID-19 pandemic. Also, disparities in uptake of the recommended vaccines still exist despite increased uptake during the pandemic. Future research should examine the disparities as well as examine regional differences in the uptake of these three adolescent vaccines.
