Common approaches for obtaining consent for vaccination

Current practices of obtaining informed consent for vaccination vary among countries, but can be broadly categorized into three approaches.

An implied consent process by which parents are informed of imminent vaccination through social mobilization and communication, sometimes including letters directly addressed to the parents. Subsequently, the physical presence of the child or adolescent, with or without an accompanying parent at the vaccination session, is considered to imply consent. This practice is based on the opt-out principle and parents who do not consent to vaccination are expected implicitly to take steps to ensure that their child or adolescent does not participate in the vaccination session. This
may include not letting the child or adolescent attend school on a vaccination day, if vaccine delivery occurs through schools.

The change comes several months after the CDC recommended a third dose for people with compromised immune systems.

The Centers for Disease Control and Prevention quietly updated its Covid-19 vaccine guidance Monday for large swaths of immunocompromised people, saying they can receive a booster dose of a Covid vaccine at least six months after completing their primary vaccination series. 

But unlike boosters for the vast majority of Americans, a booster shot for an immunocompromised individual may be their fourth Covid shot.
