New research explains the phenomenon of 'super immunity' before COVID-19

According to a new study published January 25 in the journal Science Immunology, people infected with COVID-19 after being fully vaccinated, as well as those who had it before vaccination, will have "superbugs" immunity' best prevents this disease.

Specifically, researchers from Oregon Health and Science University (OHSU), USA, took blood samples from 104 people who received 2 doses of Pfizer vaccine. Of which, 42 people have never tested positive for corona virus, 31 people have been vaccinated after getting sick, and 31 people have COVID-19 infection after being vaccinated.

After the scientists exposed blood samples of these people to the Alpha, Beta and Delta variants, they found that a combination of vaccination and natural immunity produced levels of antibodies. 'at least 10 times stronger than immunity generated from vaccination alone'.

Accordingly, the scientists concluded that additional antigen exposure from natural infection significantly increases the quantity and quality of the immune response to the pathogen, regardless of prior infection. or after vaccination. "In either case, you get an amazingly high immune response," said co-senior author Fikadu Tafesse, assistant professor of molecular microbiology and immunology at OHSU.

Besides, Mr. Tafesse also said that the possibility of getting COVID-19 after vaccination is still high due to the widespread spread of the virus. However, according to him, infected people in this case will be milder, and make predictions that the pandemic can be ended thanks to the aforementioned super immunity.
