A vaccine is an age-related immune response

Oregon: A new laboratory study from the University of Oregon Health and Science shows that older people have fewer antibodies against the novel coronavirus.
The study was published in the Journal of the American Medical Association. Antibodies are blood proteins that are made by the immune system to protect against infection. He is known as a key player in the protection against SAARC-2 infection.
“Our older populations are potentially more susceptible to a variety of diseases even if they are vaccinated,” said the senior author, PhD, senior professor of molecular microbiology and immunology at the OHSU School of Medicine.
Tafis and colleagues emphasize that although they measured low antibody response in the elderly, the vaccine would still be effective in preventing infections and serious illness in most people of all ages. Is.
“The good news is that our vaccines are really strong,” Tafsi said.
However, with vaccine doses declining in Oregon and across the United States, the researchers say their findings highlight the importance of vaccine promotion in local communities.
Immunizations reduce the spread of the virus and reduce new and potentially transmissible variants, especially for older people who are more susceptible to the infection.
“The more people get polio drops, the less the virus circulates,” Tafsi said. “Older people are not completely safe just because they have been vaccinated. People around them really need to be vaccinated against polio. At the end of the day, this study really does. That means everybody needs to be vaccinated to protect the community. ”
The researchers measured the immune response in the blood of 50 people two weeks after their second dose of the Pfizer vaccine against Covid 19. They grouped the participants into age groups and then tested their blood serum in test bulbs for the original “wild type” SARS-Co-2 virus and P1 different (also called gamma) in Brazil.
The youngest age group – In their 20s, antibody response increased almost sevenfold compared to the oldest group of people aged 70 to 82 years. In fact, laboratory results show clear linear development from a young age to the elderly: the less participant there is, the stronger the antibody response.
“Most people suffer from different conditions than younger people,” Tefsi said.
Marcel Corlin, MD, associate professor of medicine (infectious diseases) at the OHSU School of Medicine, said the findings could put older people as well as others at risk for code-19. ۔
“The vaccine produces a stronger immune response than most natural infections in older people, even if they are younger than their younger counterparts,” said Curlin. “Vaccination in this group can differentiate between serious and mild disease and may also reduce the chances of transmitting SARS Cove 2 to another person.”
