When it is possible to evaluate the effectiveness of the Preparavironmental vaccine becomes closer to patients "the second phase of clinical trials ended, but there must be a third. After that, the drug will register, so that by the autumn some vaccine will appear. The first phase of tests takes place on healthy volunteers, then gain a group more. As far as I know, in the center of the epidemiology and microbiology named after Gamalei, he conducted tests on two groups of volunteers of 20 and 30 people. Accordingly, 200 and 300 people will be recruited for a wider study. While clinical trials of different vaccines are still coming. Speaking that the drug will soon be, they just encourage the population. On young healthy volunteers, everything turned out. Now a more complete study will be conducted, the age groups will be wider, both men and women will be recruited — Now Men now participated.
So the third stage can end up by November.
The whole process takes two or three months, that is, this is a set of volunteers, vaccination and, accordingly, checking, detecting antibodies. They are produced within a month. ".
Russian researchers vaccine from coronavirus so far overtake their American colleagues. Moderna on July 27 announced that he began the third phase of testing of his drug. It is assumed that almost 30 thousand will participate in it. Volunteers. The first phase of the tests, as stated in the company, ended positively. However, the media reported on side effects at the subjects — Ozb, pain in muscles, high temperature and even loss of consciousness. About the heat also reported some volunteers who managed to test the Russian vaccine.
Vaccine rushing to put on the stream
However, in both cases, other side effects may appear at the third stage of tests, and the vaccine itself will eventually not be durable if the virus changes, Chairman of the Russian Association of Pharmaceutical Marketing Hermann Inozem residents: "The fact that the drug has moved from the first phase to The second, and from the second to the third testifies that at each of these stages there was no sharply negative and side effects. In the first two phases, much occurs in the test tube, and not in the field conditions, and much attention is paid to the toxicology and the potential of infection and reproduction of the virus.
The third phase is carried out to understand how this or that drug behaves, in this case, the vaccine, on a large scale already within the actual human body.
If COVID-19 will mutate, as, for example, mutates the flu virus every year, then the vaccine will be effective only during the year. ".
When the first vaccine will be registered
The head of the Russian Academy of Sciences Alexander Sergeev said that the sufficient volume of the drug for mass vaccination from coronavirus will appear in Russia at the beginning of next year.
