Health & Safety members have either virtually attended or read all publicly available associated documentation/meeting materials from each FDA Vaccine and Related Biological Products Advisory Committee (VRBPAC) and CDC Advisory Committee on Immunization Practices (ACIP) meeting associated with the Pfizer and Moderna vaccines, with particular attention to pediatric issues.
“Association of age and pediatric household transmission of SARS-CoV-2 infection.” Paul et al. JAMA Pediatrics, August 2021. * Note - the data from this study ended in December 2020 and so does not reflect Delta transmission.
