Booster shot (3rd dose): Moderna or Pfizer COVID-19 vaccine better?

Booster shot (3rd dose): Moderna or Pfizer COVID-19 vaccine better?


Booster shot (3rd dose): Moderna or Pfizer COVID-19 vaccine better?  Moderna’s protection for Delta far exceeds Pfizer! The third shot may have to hit Moderna!


The latest research says: Moderna vaccine is stronger than Pfizer in fighting against Delta virus!


According to Reuters: The following is a summary of some of the latest scientific research on the new coronavirus. The Moderna vaccine may be best suited to combat Delta.


According to two reports published on medRxiv before peer review on Sunday, the mRNA vaccines of Pfizer and BioNTech may not be as effective as Moderna against the Delta variant of the coronavirus.


In a Mayo Clinic Health System study of more than 50,000 patients, researchers found that the anti-infective effectiveness of the Moderna vaccine fell from 86% in early 2021 to 76% in July (when the Delta variant was dominant).


Over the same period. Researchers said that the effectiveness of the Pfizer/BioNTech vaccine has dropped from 76% to 42%.


Dr. Venky Soundararajan of Massachusetts data analysis company nference, who led the Mayo study, said that although these two vaccines are still effective in preventing hospitalization for COVID, they may be needed soon for people who were vaccinated with Pfizer or Moderna earlier this year. Inoculate Moderna booster shots.



In another study, some elderly nursing home residents had a stronger immune response after being vaccinated with the Moderna vaccine than the Pfizer/BioNTech vaccine—especially against the worrisome mutant virus.


Anne-Claude Gingras of Toronto’s Lunenfeld-Tanenbaum Institute, which led the Canadian study, said that older people may need higher vaccine doses, boosters and other preventive measures.


When asked to comment on the two research reports, a Pfizer spokesperson said: “We still believe… a third booster may be needed within 6 to 12 months after full vaccination to maintain the highest Level of protection.”


New data shows that people who received the second dose of Pfizer/BioNTech vaccine five months or more ago are more likely to test positive for COVID-19 than people who were fully vaccinated less than five months ago.


Researchers studied nearly 34,000 fully vaccinated adults in Israel who were tested to see if they had a breakthrough case of COVID-19. The results showed that 1.8% of the tests were positive. The research team reported on medRxiv on Thursday before peer review that among patients over 60, the odds of testing positive at least 146 days after the second vaccination were almost three times higher.


In this way, friends who fight against the Delta virus will be more protective than those who fight Pfizer. But everyone, even if you are fully vaccinated, pay more attention to protection when you go out. This is the most important thing!
