With more and more reports onRevolutionary infections, increasingCOVIDand certainvAccents giving less protection Against the variant of Delta now dominant, the pandemic panic increases once again, even among those which are fully vaccinated. Some vaccinated people are more vulnerable to the virus than others, although there is no simple way to say whether your body has produced asolid immune response Against Covid after having your shots. However, in recent times, more research occurs on how different people can feel various immune responses based on a number of factors, and a new study has revealed that a particular factor can increase your antibody levels. seven times.

The new study, published on July 21 in theAMERICAN MEDICAL ASSOCIATION JOURNAL, watched the difference ofImmune responses of people Produced by the Covid vaccine, and they discovered that younger people have more antibodies than the elderly.

Researchers at the University of Oregon Health and Sciences (OHSU) analyzed 50 two-week participants from their second dose of thePfizer vaccine. They divided the participants into age groups, then tested their blood serum against the original coronavirus strain and a variant, gamma, which is from Brazil.

According to the study, those of the youngest group - who were all in their 20 years - had responses from antibodies, nearly seven times higher than the oldest study group, composed of people aged 70 to 82 years old. . Researchers' data showed a clear linear progression of the highest response reduced antibody rates in the youngest participants in the lowest response in the oldest.

Marcel Curlin, MD, co-author of the study and Associate Professor at the OHSU School of Medicine, explained in a statement that even if the elderly had aAnswered antibody responseCOVID vaccines are still effective among this population. "The vaccine always produces strong immune responses compared to natural infection in most seniors, even if they are lower than their younger counterparts," Curlin explained. "Vaccination in this group can make the difference between serious and light disease and probably reduces the chances of transmitting SARS-COV-2 to another person".

TheVariant delta highly transmissible This is taken over the United States could put seniors at increased risk, particularly with regard to revolutionary infections. "Our older populations are potentially more susceptible to variants, even if they are vaccinated," saidFikdu Tafess, PhD, the main author of the study and assistant professor of molecular microbiology and immunology a school of OHSU medicine.

According to TaSesse and his colleagues, the decreased antibody reaction that comes with age further emphasizes the need for each one to be vaccinated, if they can. "The more people are vaccinated, the less the virus circulates," he said. "The elderly are not entirely safe because they are vaccinated; the people who surround them really need to be vaccinated too. At the end of the day, this study really means that everyone should be vaccinated to protect to protect the community."
