Pfizer, Modana Booster Up to 90% Effective Against Omicron: CDC

Three U.S. studies provide more evidence that a third dose of COVID vaccine is highly effective against Omicron.

Three new studies by the US Centers for Disease Control and Prevention have shown that booster shots of the Pfizer-BioNTech and Moderna vaccines are highly effective in preventing Omicron-related hospitalizations. Booster doses were 90 percent effective in keeping people away from the hospital after being infected with the Omicron variant.

According to the data, this dose was also 82% effective in preventing visits to emergency departments and emergency rooms. “It really shows the importance of getting booster doses,” said Emma Accorsi, one of the authors of the CDC, on Friday.

“Americans need to get a booster at least five months after completing the Pfizer or Moderna series, but millions of qualified people don’t.” The study consisted of the first large US study investigating vaccine protection against Omicron, health officials said.

Previous research

The paper reflects previous studies, including studies in Germany, South Africa, and the United Kingdom, showing that available vaccines are less effective against Omicron than previous versions of the coronavirus, but boosters. The dose improves the antibody that fights the virus and increases the chances of avoidance. Symptomatic infections.

The first study investigated hospitalizations and visits to emergency rooms and emergency care centers in 10 states from August to this month. The efficacy of the vaccine has been found to be optimal in preventing visits to COVID-19-related emergency departments and emergency rooms after three doses of Pfizer or Moderna vaccine.

Protection was reduced from 94% in delta waves to 82% in omicron waves. Protection from the second dose was lower, especially if 6 months had passed since the second dose. Authorities are emphasizing the goal of preventing serious illnesses as well as infections.

The second study focused on COVID-19 cases and mortality in 25 states from the beginning of April to the end of December. The boosted people had the best defense against coronavirus infection, both during the period when Delta was dominant and when Omicron was hijacked. These two articles were published online by the US Centers for Disease Control and Prevention.

Third study

The Journal of the American Medical Association has published a third study, also led by CDC researchers. It examined people who were positive for COVID-19 from December 10th to January 1st at more than 4,600 test sites across the United States.

Three shots of the Pfizer and Moderna vaccines were about 67% more effective against symptomatic diseases associated with Omicron compared to unvaccinated people. However, the researchers found that the two doses did not provide significant protection against Omicron when measured months after the completion of the original series.

“If you qualify for a booster and don’t have it, you’ll need to get one because it’s not up to date,” CDC director Dr. Rochelle Walensky said at a briefing at the White House on Friday. rice field.
