CHICAGO, July 22 (Hfrance.fr) - Advisors from the U.S. Centers for Disease Control and Prevention will examine evidence on Thursday suggesting that a booster dose of COVID-19 vaccines could increase protection in people with compromised immune systems. weakened.
Data presented before the meeting indicates that people with weakened immune systems have a reduced immune response afterfrom the recommended primary series compared to healthy individuals.
"Emerging data suggests that an additional dose of COVID-19 vaccine in immunocompromised people improves antibody response and increases the proportion of those who respond, "slides released before the meeting showed this.
The committee has no plans to vote on a recommendation on whether or not to administer additional doses. This could be decided at a later meeting.
In small studies, the short-term side effects of a third dose of vaccines at MRNA - such as those manufactured by BioNTech / Pfizer Inc (PFE.N) or Moderna Inc (MRNA.O) - were about the same as seen with the first two doses, the CDC said in its presentation.
An estimated 2.7% of American adults live with a weakened immune system, according to the CDC presentation, based on data from 2013. The group includes people living with HIV / AIDS, cancer, and people who have suffered from cancer. organ transplant or autoimmune disease who take drugs to suppress their immune response.
These people are at increased risk for serious illness and deaths from COVID-19.
Last we ek, Israel began administering third doses of the Pfizer / BioNTech vaccine to immunocompromised p people, including those who have had a heart, lung, kidney or liver transplant; and cancer patients receiving chemotherapy. learn more
Some experts believe the CDC is approaching a similar recommendation in the United States.
The CDC has warned people whose system weakened immune to take precautions even if they are fully vaccinated against COVID-19.
The virus not only poses an additional risk to human health immunocompromised, but because it takes longer for these people to clear the virus, scientists believe infections could lead to new variants as the virus continues to replicate unchecked, which some of the studies have shown.
