A new study from Brigham and Women’s Hospital found that the coronavirus protection provided by Moderna’s mRNA vaccine was strong and did not diminish for more than five months after the second shot.
In a study of more than 30,000 participants, the vaccine was safe and effective for an average of 5.3 months after the second vaccination. Over time, Shot was 93.2% effective in preventing COVID-19 illness and 98.2% effective in preventing severe illness.
Strong protection was maintained in all subgroups, including the elderly and participants with comorbidities. Researchers have also found that there is protection against the asymptomatic coronavirus.
Dr. Lindsey Baden, BWH Infectious Disease Specialist and Corresponding Study author “Overall, our results continue to show that vaccines work very well in the prevention of COVID-19,” published Wednesday in the New England Journal of Medicine.
Baden said: “We continue to investigate questions about the post-vaccination immunity period and the effects of mutants. However, investigating the potential for weakened immunity shows evidence that the vaccine is still very protective. increase.”
The data in this study were collected before the delta variant hit the United States, so they didn’t fully inform the general public about immunity behavior associated with endurance and viral changes, Baden told Herald. Told.
“Looking at national epidemiology, I think there is still substantial protection against deltas against severe illness,” he said.
The issue of immunity has become a hot topic in the growing conversation about coronavirus boosters. Evidence of weakened immunity may provide a stronger debate for boosters.
An advisory group at the Centers for Disease Control and Prevention will meet this week to compile the data and decide whether to provide Pfizer boosters to the general public.
