Uncertainty now dominates the COVID vaccine outlook after official recommendations were stripped for a variety of groups.

The US Centers for Disease Control and Prevention has updated its immunization schedule for children, days after US Health and Human Services Secretary Robert F. Kennedy Jr. announced that Covid-19 vaccines would be struck from the list of recommended shots for healthy children and pregnant women.

The Centers for Disease Control and Prevention now says that kids with no underlying health conditions "may receive" COVID-19 vaccines, dropping a broad recommendation for all children to get vaccinated against the virus.

Insurance coverage typically follows federal recommendations, so anyone who is healthy and under 65 is likely to have to pay out of pocket to get the shot ‒ which runs about $200 ‒ if they can get it. It's not clear what insurance companies will do about the new recommendations.

Existing evidence on the safety and efficacy of getting a COVID vaccine in pregnancy all points the same way: the shot is important for maternal and fetal health.

Health Secretary Robert F. Kennedy Jr. recently announced more key changes to the CDC recommendations for COVID-19 vaccination. Two health experts answer questions about what the changes mean.
