● The biggest concerns for parents have consistently been the long term side effects of the COVID-19 vaccine on kids, and whether the COVID-19 vaccine has been tested enough for kids; for every wave of our survey, over half of all parents mention these as major concerns. 

● A handful of groups continued to hold elevated levels of certain concerns from September to November, such as Republican, Asian, and rural parents. Some others (like Democrats, Hispanics, older fathers) returned to the lower initial (June) levels for most concerns after the September spike. College educated parents have stayed at essentially stable (and low) levels of concern over time for almost all concerns examined. Overall, these trends not only suggest that groups are polarized over COVID-19 vaccine concerns for kids, but also that certain groups are still polarizing over time - particularly vaccine novelty and risk for long term side effects of the vaccine. 

● Overall, parental concerns over the COVID-19 vaccine for kids were the lowest in June 2021, peaked in September 2021, and then decreased somewhat in November 2021. 

● Republican, Black, and rural parents, as well as younger (under 35) mothers and parents who say they are unlikely to vaccinate their children, are among the groups with the greatest proportion of people expressing various concerns. 

● College-educated and Democratic parents, as well as parents who will likely or who have already vaccinated their kids, have consistently been among the groups with the fewest expressing concerns. Fathers - particularly fathers 35 or older - also tend to have some of the lowest levels of parental concerns.
