A new U.N. AIDS agency report says the sudden withdrawal of U.S. funding has caused a "systemic shock" to the global effort against AIDS and HIV. Years of American-led investment into AIDS programs has reduced the number of people killed by the disease to the lowest levels in more than three decades. U.S. aid has also bought lifesaving medicines for some of the world's most vulnerable people and rolled out testing and prevention services across Africa. The UNAIDS report released Thursday says if U.S. funding is not replaced it could lead to more than 4 million AIDS-related deaths and 6 million more HIV infections by 2029.

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.

For many Americans, it's not clear how easy getting a COVID-19 vaccination will be. Health Secretary Robert F. Kennedy Jr. recently said the shots are no longer recommended for healthy children and pregnant women, usurping a decision normally made by scientific experts. Days later, the Centers for Disease Control and Prevention said healthy children "may" get COVID-19 vaccinations, removing stronger language that they "should" get them — and CDC's website now has no advice for pregnant women. The biggest questions are whether people can get a vaccine even if it's not recommended for them — and if insurance will pay.

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.

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.
