Researchers from the United States have shown that the production of antibodies after receiving the Moderna vaccine is higher than after the Pfizer preparation. Article researchers Published in Jama Network Open magazine.
Researchers analyzed blood samples 167 vaccinated employees of the University of Virgin University, collected, starting from a week to a month after receiving the second dose of the drug. 79 people from this number received the Pfizer Vaccine, 88 – Moderna. 38 percent of the participants of the study were over 50 years old, 72 percent of the total – Women.
It turned out that more IgG antibodies were produced in people who received the MODERNA vaccine – 68.5 micrograms per milliliter against 45.9 in vaccinated PFizer. In those of the latter, who was over 50 years old, the production of antibodies was lower compared to younger people – 31.1 micrograms per milliliter against 59. At the same time, in the grafted moderna, such dependence was observed.
Scientists recognize that they have not analyzed the content of neutralizing antibodies that block the penetration of coronavirus into the cell. It is also not necessary to draw conclusions about the effectiveness of vaccines based on the level of production of antibodies after their introduction, they called.
