Every time someone claims immunocompromised people can’t take the COVID vaccine, more of my hair turns gray.
It is the opposite — People who are immunocompromised need different, bigger and more frequent dosing than the rest of us to elicit an immune response.
Most people who are immunocompromised can (and I would argue, should!) get vax'd.
(There are some severely immunosuppressed people on some specific therapies that cannot get vaccinated, or who have to carefully time vaccination–please consult the physician/team writing for your immunosuppression)
