Comparative analysis of COVID-19 RNA “Moderna” Պ “Pfizer” vaccines shows that “Moderna” vaccine is more effective in preventing symptomatic, laboratory-confirmed COVID-19 cases, extreme disease և death :
New England Journal of Medicine A study published in the journal found that both vaccines were more than 90% effective, but there were some differences between them that could be used by health care providers and organizations when using the vaccine in the general population.
The comparison is based on the US Department of Veterans Health Database. Two groups were selected: 219,842 veterans who received the “Pfizer” vaccine, 219,842 veterans who received “Moderna” in 2021. from January 4 to May 14. The study was conducted at different times when the “Alpha” or “Delta” strains were predominant. Pfizer recipients had a 27 percent higher risk of infection and a 70 percent higher risk of hospitalization when the Alpha version was predominant.
During the 12-week study, when the Delta version was predominant, the risk of infection was slightly higher in the Pfizer group, indicating that both vaccines were effective, with fewer cases, but regardless of the predominant strain. The efficiency of “Moderna” is a little higher.
The research was conducted by T. H. By the Harvard TH Chan School of Public Health, Brigham’s Brigham and Women’s Hospital նախարարության Department of Veterans Affairs.
