● All investigated parental concerns about vaccinating children against COVID-19 have increased significantly from June 2021 to September 2021 across all demographic groups. A few of these jumps were as high as 15 percentage points or more for certain concerns and for demographic groups. 

● Certain groups of parents are more likely to express major concerns about the COVID-19 vaccine for their kids, including younger mothers, parents of younger children, parents of children who have not yet been vaccinated, Republicans and Independents, Hispanic and Black parents, the non-college educated, and rural residents. 

● Long-term effects of the COVID-19 vaccine, followed by whether the COVID-19 vaccine has been tested enough, were often the top concerns among parents. 

● Both the likelihood of vaccinating children under 12 and vaccination status in children ages 12 to 18 are strongly related to parent vaccination status, as well as student mode of school instruction.
