With age, the body's immune response weakens, possibly mitigating the side effects of vaccinations. This opinion was expressed by Ilya Yasny, a bioengineer, candidate of chemical sciences, head of the scientific expertise of the Inbio Ventures fund.
Earlier it was reported that from the Sputnik V vaccine in people over 60 years of age, adverse events after an injection, such as fever, headache and muscle pain, are much less pronounced and are much less common than in young people. However, this does not affect the effectiveness of the vaccine itself.
With age, the immune system works weaker - it can be assumed that this is why the side effects of vaccination are less pronounced, which, in fact, are immune reactions to the introduction of the drug, - KP. RU quotes Yasny.
He added that this issue is still poorly understood. Ideally, the production of antibodies to coronavirus in older people should be less active, however, it is possible that different elements of the immune system "may work in different ways."
As NEWS.ru wrote, doctor and senator Sergei Leonov explained the main differences between Russian vaccines against coronavirus: EpiVacCorona, KoviVac and Sputnik V. "EpiVacCorona", he said, is the mildest vaccine, it is artificially synthesized and will have fewer side effects. The expert called "Sputnik V" an "average version", the body's reaction to it is quite active, often accompanied by an increase in body temperature. The most vigorous vaccine is CoviVac. It carries a large number of antigens, the body's reaction to it will be more pronounced, and as a result, a more stable immunity is developed, Leonov said.
The doctor advised young and middle-aged people with good health to be vaccinated with KoviVac, the elderly with EpiVacKorona, and Sputnik V according to indications.
