measles vaccine

Child vaccination rates in the United States fell during the COVID-19 pandemic as many children skipped doctors appointments and states eased vaccine requirements during remote learning, according to a government study released on April 21.

According to the Pharmaceutical Research and Manufacturers of America (PhRMA), there are 264 vaccines in development to prevent and treat diseases.

The U.S. Food and Drug Administration approved the expanded use of Adacel to include repeat vaccination to help protect against tetanus, diphtheria and pertussis.
