Three studies used by RFK Jr and allies to justify controversial vaccine policies changes facing new scrutiny

Scientists praise moves to investigate, retract or remove controversial studies. The authors stand by their work

In some cases, the actions occurred years after scientists first raised alarms about the studies’ scientific merits.
