A research discovered that people vaccinated against Coronavirus and people who are recovering from the virus produce the same kind of white blood cells that create antibodies. The study was realized by a team of researchers from the Vanderbilt University Medical Center, and it was published in the Cell Reports journal this week.
“We were surprised to discover that there are so many shared antibodies between individuals after SARS-CoV-2 infection, but that is a good sign. It was encouraging to find that an mRNA vaccine also induces those clones, which in part explains why these antibodies work so well in so many people,” declared the author of the paper, director of the Vanderbilt Vaccine Center, James Crowe Jr.
The vaccines give rise to an immune response in the body with the help of a viral protein, and at the moment, they offer protection against the new delta variant that has caused outbreaks all around the world. However, researchers believe that more dangerous variants can emerge, affecting those vaccinated as well. The new study can provide information that could help researchers create new vaccines with a higher efficiency rate.
B cells, or B lymphocytes, are the white blood that create antibodies. A cell matures into cloned identical cells when it is stimulated by a virus. Those matures B lymphocytes are the ones that generate millions of antibodies that fight against the virus.
According to the study, 27 public clonotypes were discovered, all shared by those who recovered from COVID-19 and those who had never been infected but had taken the vaccine.
