New findings on effectiveness of third injections

New research from the Centers for Disease Control and Prevention (CDC) suggests that the effectiveness of Pfizer and Moderna’s third dose of the vaccine will drop significantly by the fourth month.

The effectiveness of the Pfizer and Moderna vaccines reduced hospitalizations by 91% in the first two months after the third dose.

However, by the fourth month, that number will drop to 78%. The results of the study were published on February 12, according to AFP.

“The protection provided by the mRNA vaccine diminishes in the months following the third dose of the vaccine. This new finding reinforces the importance of investigating additional booster doses to maintain or improve protection,” the researchers concluded.

The new study is based on more than 241,204 emergency room visits and 93,408 Covid-19 hospitalizations between August 26 and January 22, 2021.

Earlier, Anthony Fauci, a senior medical adviser to President Joe Biden, said at a White House briefing on Feb. 9 that a group of people may need a fourth dose. . Small people with a poor immune response, such as the elderly and immunocompromised people.

In another development, on February 11, the U.S. Food and Drug Administration (FDA) approved a new antibody therapy called bebtelovimab, developed by Eli Lilly.

The drug is given into a vein and can be used to treat mild to moderate Covid-19 in people 12 years and older.

Data from clinical trials showed strong resistance to the Omicron variant.
