(ORDO NEWS) — American military doctors from the Walter Reed National Military Medical Center in Maryland in the United States announced the completion of the first phase of testing a “supervaccine” against coronavirus.
According to them, the drug will be able to protect the body not only from the main strains, but also from any other mutations.
The new drug is a peptide one – when using such a vaccine, fragments of the viral protein that are incapable of self-replication enter the body. The body reacts in such a way that it selects the necessary antibodies for different parts of the viral protein and can neutralize the virus even with new mutations.
Experts are confident in the safety level of the vaccine, because the entire virus family, and not just a specific strain, is considered as an object of study. That is, the studied property of a particular virus is searched for in the entire group.
At the same time, a number of experts spoke on this matter and noted that the creation of such a vaccine is impossible in principle. “I have heard similar statements from the developers of the influenza vaccine for decades, not even years.
Both influenza and Sars-Cov-2 are fast-mutating RNA viruses that continually produce more and more variants.
So I personally do not have an answer to the question of which part of the viral genome can be considered stable and unchanging enough to develop a single vaccine based on it, which will not become obsolete as new mutations appear, “a professor at the School of Pharmacy at the University of Maryland commented on his skepticism. senior editor of BMJ magazine Peter Doshi.
