Federal agencies said studies have shown those may not be adequately protected with just two shots.
The earliest that immunocompromised people who received a third mRNA vaccine shot can get a fourth shot as a booster would be February. The agency said people can choose that booster from one of three coronavirus vaccines available in the United States.

Which may naturally decrease against infection over time.
The World Health Organization has supported additional doses for people with weakened immune systems, while calling for a global moratorium on booster programs for otherwise healthy people until the end of the year, so that more doses are allocated to low-income countries with lower rates. can be done.
