More chaos CDC updates COVID vaccine recommendations, but not how RFK Jr. wanted Mixed messages only add to uncertainty about vaccine access for kids, pregnant individuals.

Kennedy Jr. earlier this week. In a 58-second video posted on social media on Tuesday, May 27, Kennedy said he was unilaterally revoking the CDC's recommendations that healthy children and pregnant people get COVID-19 vaccines. "I couldn’t be more pleased to announce that, as of today, the COVID vaccine for healthy children and healthy pregnant women has been removed from the CDC recommended immunization schedule," Kennedy said in the video. The health agency's immunization schedules were not, in fact, updated at the time of the announcement, though. The Washington Post subsequently reported that the CDC was blindsided by the announcement. Five hours went by after the video was posted before CDC officials said they received a one-page "secretarial directive" about the changes, which was signed by Kennedy and puzzlingly dated May 19, according to the Post. Late Thursday, the CDC updated the immunization schedules. Contradicting what Kennedy said in the video, the CDC did not remove its recommendation for COVID-19 vaccines for healthy children in the child and adolescent immunization schedule. Instead, it added a stipulation that if a child's doctor agrees with the vaccination and parents "desire for their child to be vaccinated," healthy children can get vaccinated. In practice, it is unclear how this change will affect access to the vaccines. Health insurers are required to cover vaccines on the CDC schedules. But, it's yet to be seen if children will only be able to get vaccinated at their doctor's office (rather than a pharmacy or vaccine clinic) or if additional consent forms would be required, etc. Uncertainty about the changes and requirements alone may lead to fewer children getting vaccinated. In the adult immunization schedule, when viewed "by medical condition or other indication" (table 2), the COVID-19 vaccination recommendation for pregnancy is now shaded gray, meaning "no guidance/not applicable." Hovering a cursor over the box brings up the recommendation to "Delay vaccination until after pregnancy if vaccine is indicated." Previously, COVID-19 vaccines were recommended during pregnancy. The change makes it less likely that health insurers will cover the cost of vaccination during pregnancy. The change is at odds with Trump's Food and Drug Administration, which just last week confirmed that pregnancy puts people at increased risk of severe COVID-19 and, therefore, vaccination is recommended. Medical experts have decried the loss of the recommendation, which is also at odds with clear data showing the risks of COVID-19 during pregnancy and the benefits of vaccination. The President of the American College of Obstetricians and Gynecologists (ACOG) put out a statement shortly after the Tuesday video, saying that the organization was "extremely disappointed" with Kennedy's announcement. "It is very clear that COVID-19 infection during pregnancy can be catastrophic and lead to major disability, and it can cause devastating consequences for families," ACOG President Steven Fleischman said.
