The study, published in the New England Journal of Medicine, followed individuals with Pfizer and Moderna vaccines over a 2-month period. The research was conducted in Texas and California.
While the coronavirus pandemic affecting the whole world continues, various vaccine applications continue in various countries. A review of 23,200 health workers at the University of Texas Southwestern Medical Center tracked participants over a nearly two-month period. Similar research was also carried out on 36,600 people in California. Let’s note to the participants that any of the Pfizer-BioNTech and Moderna vaccines have been made.
A review of health workers in Texas, also published in the New England Journal of Medicine, found that while the Pfizer vaccine was used, coronavirus cases decreased dramatically in the period after vaccination, 2.6% of unvaccinated individuals were positive, although the positivity rate in individuals who received the first dose of their vaccine was 1.82%, in other words, the positivity rate in individuals who received the first dose of the vaccine decreased by 31%.
In the same study, the positivity rate of individuals who were vaccinated with all doses of any of the vaccines mentioned in the same study has decreased by 0.05%, or less than 1%.
In another study, also published in the New England Journal of Medicine, and in research conducted in California – 36,600 people – individuals with Pfizer or Moderna vaccines were examined and approximately 77% of participants were vaccinated with all doses.
While 0.9% of individuals who received a single dose of the vaccine tested positive, most of the positivity was in the first weeks after vaccination, meaning scientists believe most of these individuals may have been infected with the virus before they were vaccinated. Only 37% of the individuals who received both doses, or 0.13%, were positive.
As new research shows, vaccination is of great importance for the effective immune response and the clinical course of infection.
The new research was published in the New England Journal of Medicine.
