Vaccine immune response linked to age

Updated:2 months, 1 week ago

New Delhi, July 23 (ANI): A new laboratory study from Oregon Health and Science University suggests that older people appear to 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. They are known to be key players in protection against SARS-CoV-2 infection. Tafesse and colleagues emphasized that even though they measured diminished antibody response in older people, the vaccine still appeared to be effective enough to prevent infection and severe illness in most people of all ages. However, with vaccine uptake slowing in Oregon and across the United States, researchers say their findings underscore the importance of promoting vaccinations in local communities. Vaccinations reduce the spread of the virus and new and potentially more transmissible variants, especially for older people who appear to be more susceptible to breakthrough infections.
