As official health guidance changes, scientific groups are stepping in with evidence-based recommendations
The US Department of Health and Human Services (HHS) is adopting a recommendation from independent advisers to drop thimerosal, a preservative found in about 4% of flu vaccines, despite evidence that it poses no risks and helps prevent bacterial and fungal infections.
But Robert F Kennedy Jr, the HHS secretary, has not adopted two other votes from the advisory meeting: recommending annual flu vaccines for everyone over the age of six months and RSV shots for infants.
