According to CDC, third shots of coronavirus vaccines significantly reduced the risk of hospitalization due to COVID in people with weakened immune systems - The New York Times.
The Pfizer (NYSE:PFE) - BioNTech (NASDAQ:BNTX) and Moderna (NASDAQ:MRNA) vaccines were roughly 88% effective against hospitalizations in immunocompromised people who had received a third dose, compared with 69% in people with only two doses (p <0.001), the agency said.
Three doses of mRNA vaccines were 97% effective in preventing hospitalizations in individuals without any immunocompromising conditions, compared to 82% effective in people who received only two doses.
The data came from a study of people treated at 21 American hospitals from August 19 to December 15, 2021. The new study evaluated roughly 1,100 adults with weakened immune systems and 1,900 other adults.
Federal regulators authorized a third Pfizer-BioNTech or Moderna dose for some immunocompromised people in August 2021.
In October, CDC said that immunocompromised people could also get a fourth dose of vaccine, as soon as early 2022 â as a way of enhancing or restoring protection.
For immunocompromised people with a single shot of the Johnson & Johnson (NYSE:JNJ) vaccine, CDC advises booster dose of Moderna or Pfizer-BioNTech shots.
Also, booster doses have shown to bolster peopleâs defenses against infection, even if the overall protection against that variant is weaker.
