Earlier this month, the US Centers for Disease Control and Prevention (CDC) recommended Pfizer's COVID-19 messenger RNA (mRNA) vaccine for children between 5 and 11 years of age-that's 28 million children. Yet surveys show that 42 to 66% of parents of these children are reluctant or opposed to seeking this protection. Without vaccination, it is likely that almost everyone-including young children-will be infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at some point in their lives. So, the question for parents and caregivers is: Which is worse, vaccination or natural infection?

Background: This study aimed to investigate the sociodemographic and behavioral factors related to increased influenza vaccination uptake during the COVID-19 pandemic in South Korea, particularly among adults not eligible for free vaccination.
Methods: Analyzing data from 78,815 participants in the Korea National Health and Nutrition Examination Survey (2010-2021), we assessed trends in influenza vaccination coverage. Various sociodemographic factors, behavioral aspects, and psychological stress levels were assessed using multivariable logistic regression to evaluate the difference in vaccination response during pre-/post-COVID-19 periods.
