Medical associations representing hundreds of thousands of doctors, medical professionals and scientists in the United States are suing the leaders of US health agencies for limiting who can get Covid-19 vaccines and for undermining overall vaccine confidence.

Several leading medical organizations on Monday filed a lawsuit against the U.S. Health Secretary Robert F. Kennedy Jr. and the Department of Health and Human Services, arguing that current policies on COVID-19 vaccines pose an imminent threat to public health.

The suit addresses the scrapping of Covid-19 vaccination recommendations for children and pregnant women and the dismantling an influential expert panel that advises the government on immunizations.
