released a statement on Friday that those with moderately to severely compromised immune systems should receive the third dose after the initial two doses.“Emerging data suggest some people with moderately to severely compromised immune systems do not always build the same level of immunity compared to people who are not immunocompromised.
In addition, in small studies, fully vaccinated immunocompromised people have accounted for a large proportion of hospitalized breakthrough cases (40-44%),” Walensky said.Those who are immunocompromised and get the virus are also more likely to expose others.Studies have indicated that the initial vaccine doses are effective at a rate of 58-72 percent in immunocompromised people as opposed to 90-94.
