Pharmaceutical manufacturers report that one clinical trial after another has been successfully completed in volunteers. Apparently, we will soon have a few of them - the WHO called nine promising, but the list is not limited.
However, skeptics are seriously concerned about the safety of vaccines. People rightly try to find out if there are any side effects associated with the use of the drug for months or even years after clinical trials. This is not an unnecessary measure - it is no secret that hastily prepared vaccines in history have caused serious complications in patients. Therefore, the news that a mass vaccination against COVID-19 may begin soon worries citizens. Given that the development and study of the fastest samples took only a few months, the risks of a poorly studied vaccine are more alarming than the complications of the coronavirus.
Andrei Malyavin, chief freelance pulmonologist at the Central Federal District of the Russian Ministry of Health, is confident that safety requirements will be met, Gadin.Net reports.
"This is the position of the Ministry of Health, and there is no need to worry about the relevant indicators. But there is another nuance: You must understand that a 100% effective vaccine will not be produced in the coming months. In other words, it is useless to wait for the production of a drug that guarantees 100% protection from infection. And this is not the fault of scientists who are now developing vaccines on different platforms. SARS-CoV-2 is the result of a highly mutated virus. Some antigens are constantly changing. It is simply not possible to get vaccinated on the first try, which will close all the gaps in the virus. But on the other hand, only a fraction of the antigens change and remain the same - so fears that the vaccine will not work at all are unfounded. It is likely that a high-quality vaccine will be available in a few years, ”the expert predicts.
For example, the papillomavirus vaccine was completed after about 10 years. Just like the hepatitis B vaccine. However, Andrei Malyavin believes that even a vaccine against coronavirus is worth getting:
"In all cases, it will be developed at a high enough level, because a lot of effort is put into its preparation. Now the development of science allows us to mathematically simulate many processes without resorting to long experiments in reality.
