Robert F. Kennedy Jr. is reshaping U.S. health policy as HHS secretary, and doctors say his changes are eroding trust. Survey results show Americans' confidence keeps sliding, not rising. Kennedy has cut vaccine guidance, dismissed advisers and pushed claims medical groups call unverified. Doctors warn this confusion leads people to skip shots. They say that raises the risk of outbreaks. Polls from KFF and Gallup show trust in the CDC falling across groups. HHS says Kennedy is adding transparency and accountability. Critics say he is doing the opposite.

Health Secretary Robert F. Kennedy Jr.'s new vaccine advisers added confusion Friday to this fall's COVID-19 vaccinations. For the first time since the shots were developed, the group has declined to recommend their use — instead leaving the choice up to those who want them. The Food and Drug Administration recently put new restrictions on this year's shots from Pfizer, Moderna, and Novavax, reserving them for people over 65 or younger ones at higher risk. The Centers for Disease Control and Prevention advisers declined to recommend that those people seek a shot but narrowly avoided urging states to require a prescrption for those who want one.

COVID-19 activity is rising in much of the country. Data shows overall respiratory virus spread is very low in the U.S. But COVID-19 is rising in most states, with more people of all ages going to emergency rooms because of it. The stratus variant is most common. It can cause a "razor blade" sore throat and is considered a "variant under monitoring" by the World Health Organization, but it is only marginally better at evading people's immune systems. Flu and RSV activity remain very low. Doctors say hot summer weather can drive people indoors where respiratory viruses like to spread.

COVID-19 activity is rising in much of the country. Data released Friday by federal health officials shows overall respiratory virus spread is low. But COVID-19 is rising in many states in the mid-Atlantic, the South, the southeast and on the West Coast. More people of all ages are going to emergency rooms because of COVID-19. Flu and RSV activity remain very low. Doctors say hot summer weather can drive people indoors where respiratory viruses like to spread.

Measles cases in the U.S. are at their highest in more than three decades. The U.S. Centers for Disease Control and Prevention says the U.S. has 1,288 cases since the beginning of the year. That's higher than 2019, when there 1,274 cases driven by 22 outbreaks over 12 months. Eighteen states have seen outbreaks this year. Experts fear the U.S. may lose its status as having eliminated measles. There are also large outbreaks of the vaccine-preventable disease in Mexico and Canada.

The nation's top public health agency has posted new recommendations that healthy children and pregnant women may — but no longer should — get COVID-19 vaccinations. The change comes days after U.S. Health Secretary Robert F. Kennedy Jr. announced that COVID-19 vaccines will no longer recommended for healthy children and pregnant women. Kennedy announced the coming changes in a 58-second video posted on the social media site X on Tuesday. No one from the CDC was in the video, and CDC officials have referred questions about the announcement to Kennedy and the U.S. Department of Health and Human Services.

A new variant of COVID-19 is circulating in parts of the world and may be driving an increase in cases in the eastern Mediterranean, Southeast Asia and western Pacific regions. The World Health Organization said Wednesday the new variant called NB.1.8.1 is increasing globally and in mid-May had reached nearly 11% of sequenced samples. Current vaccines are expected to remain effective and there's nothing to suggest that the disease associated with the variant is more severe. Airport screening in the United States has detected the new variant in international travelers arriving in California, Washington state, Virginia and New York.

U.S. Health Secretary Robert F. Kennedy Jr. says COVID-19 vaccines are no longer recommended for healthy children and pregnant women. In a 58-second video posted on the social media site X, Kennedy said he removed COVID-19 shots from Centers for Disease Control and Prevention's recommendations for those groups. No one from the CDC was in the video. U.S. health officials, following recommendations by infectious disease experts, have been urging annual COVID-19 boosters for all Americans ages 6 months and older. A CDC scientific advisory panel is set to meets in June and will consider recommending vaccination for high-risk groups but still giving lower-risk people the choice in getting a shot. But Kennedy decided not to wait.
