A federal judge has halted Robert F. Kennedy Jr.'s vaccine overhaul. The court's ruling reverses several changes to the CDC's vaccine recommendations on childhood vaccinations. These changes were part of a planned reform of vaccination rules. The judge's decision stopped their implementation. The article does not provide other specific details about the scope of the changes or statistics. The group Children's Health Defense, led by RFK Jr., has previously unsuccessfully challenged the safety of COVID-19 vaccines in court.[1] The US Supreme Court rejected their appeals in June.[1]
