When Robert F Kennedy Jr announced that the US would stop recommending covid-19 vaccines for healthy children and pregnancies, he bypassed standard protocols and set the stage for future vaccine rollbacks

One of the top vaccine experts at the US Centers for Disease Control and Prevention (CDC), Lakshmi Panagiotakopoulos, resigned on 4 June – a week after Robert F Kennedy Jr announced that covid-19 vaccines would no longer be recommended for most children and pregnancies.

The announcement set off several days of confusion around who will have access to covid-19 vaccines in the US going forward. In practice, there hasn’t been a drastic change to access, though there will probably be new obstacles for parents hoping to vaccinate their children. Still, Kennedy’s announcement signals a troubling circumvention of public health norms.
“My career in public health and vaccinology started with a deep-seated desire to help the most vulnerable members of our population, and that is not something I am able to continue doing in this role,” said Panagiotakopoulos in an email to colleagues obtained by Reuters.
Panagiotakopoulos supported the Advisory Committee on Immunization Practices (ACIP), which has advised the CDC on vaccine recommendations since 1964. But last week, Kennedy – the country’s highest-ranking public health official – upended this decades-long precedent. “I couldn’t be more pleased to announce that, as of today, the covid vaccine for healthy children and healthy pregnant woman has been removed from the CDC recommended immunisation schedule,” he said in a video posted to the social media platform X on 27 May.
Despite his directive, the CDC has, so far, only made minor changes to its guidance on covid-19 vaccines. Instead of recommending them for children outright, it now recommends vaccination “based on shared clinical decision-making”. In other words, parents should talk with a doctor before deciding. It isn’t clear how this will affect access to these vaccines in every scenario, but it could make it more difficult for children to get a shot at pharmacies.
