Modana and Pfizer COVID vaccination Protects against many coronavirus mutants, including advanced ones Infectious Delta, another study confirms.

Breakthrough infections in vaccinated people vaccination‘Ability to protect from new variants.

Akiko Iwasaki, a professor of immunobiology at Yale University, who co-authored the study, said the shot “induces high levels of antibodies against deltas and most mutants.” “And two shots are better than one.”

Booster shots also help protect against infection, according to findings.They were published in the journal on October 11th Nature..

For this study, researchers collected blood samples from 40 healthcare workers between November 2020 and January 2021 prior to vaccination.

In the next few weeks, more blood samples were collected after volunteers received the first and second doses of Moderna or Pfizer-BioNTech. vaccination..

Blood samples were then exposed to 16 coronavirus variants, including Delta, which is currently the most common strain in the United States. Blood collected after vaccination showed an enhanced immune response, which varied by mutant and individual.

In general, the immune response was strong against the delta variant, even stronger after the participant’s second shot.

Delta-related breakthrough infections vaccination According to Iwasaki, it failed, but instead it is due to the extreme infectivity of mutants that can overwhelm the immune defense.

Researchers also found that people who were infected with COVID before vaccination had a stronger immune response after receiving the injection than those who had never been infected.

“Recovery from the first infection is like getting the first infection vaccination Shot “.

She suggested that booster shots could have a similar effect and increase the levels of antibodies and T cells that protect against infection.
