FDA authorizes additional Covid-19 vaccine doses for certain immunocompromised people

The FDA amended the emergency use authorization for the Pfizer/BioNTech and Moderna Covid-19 vaccines to allow for an additional dose for certain people with compromised immune systems. That group includes "specifically, solid organ transplant recipients or those who are diagnosed with conditions that are considered to have an equivalent level of immunocompromise," the agency wrote in a statement Thursday.
