CDC plans to let people with weakened immune systems get a booster earlier

The CDC estimates that about 2.7 percent of adults — 7 million people — are immunocompromised, a group that includes patients with medical conditions that weaken their immune response, as well as people taking immune-suppressing drugs because of organ transplants, cancer or autoimmune diseases. Also on the list are people with advanced or untreated HIV infections, and those who have chronic medical conditions that can weaken immune response, such as chronic kidney disease.
