The available vaccines in the United States are still under EUA, Emergency use authorization and individuals must be provided the option to decline since they are still experimental.  The Pfizer COMIRNATY version that has some FDA approval is not available in the United States and is still running studies on children ages 6-12 until May 31, 2024, therefore we Parents need to wait until those studies are complete in order to have a full understanding of what we are choosing to inject in our children’s bodies and our own.  https://www.fda.gov/media/151710/download
