Scientists from Yale University in the United States issued an article in the journal Nature on the 11th and pointed out that a new study they carried out found that two commonly used new crown vaccines can prevent a variety of new crown virus variants, including the particularly infectious Delta strain
In this study, a research team led by Professor Akiko Iwasaki of immunobiology collected blood samples from 40 medical staff between November 2020 and January 2021, and the volunteers received the first and second doses.
As a result, they found evidence of an enhanced immune system response in all blood samples-although the intensity of the response varies from strain to individual
According to the researchers, this result shows that the vaccines of Modena and Pfizer/New Biotech have indeed enhanced the human immune system's response to infection
At present, people who have been vaccinated can still be infected with the delta mutant strain.
In addition, the researchers divided healthy volunteers into two groups: volunteers who had been infected with the new coronavirus before vaccination and volunteers who had not been infected with the new coronavirus before vaccination
