The US government fired Susan Monarez. She was the director of the Centers for Disease Control and Prevention (CDC). The government said she did not agree with the president’s plans.

After Susan Monarez left, some other leaders at the CDC also left their jobs. They said they did not like the new rules about vaccines. They also said they did not feel safe at work.

The new rules say only older people can get the new Covid vaccine. Younger people and children cannot get it unless they are sick. Many people are worried about these changes.
