Scientists believe that vaccines against coronavirus will not stop the epidemic

American and British scientists believe that the emerging vaccines for coronavirus will not be able to stop the spread of the epidemic. Taking into account that the authorities are rushing them to invent it, the first vaccines, even if they are invented, will have a very limited spectrum of action.

According to a researcher at London's Imperial College Robin Shattock, the first vaccines will not be able to protect people from infection with coronavirus. In conditions when the medicine needs to be provided quickly, the question arises for scientists on what to focus their attention on: to make the vaccine protect against infection, to fight the disease itself, or to prevent the progress of the disease in a serious form. The scientist concludes that, first of all, it is necessary to protect the population from experiencing the disease in a serious form. According to the British researcher, such a vaccine can be used until a better version is released.

“Vaccines should protect against the disease itself, and not from infection", writes Bloomberg, citing the words of the immunologist of the American pharmaceutical company Scripps Research Denis Burton.

According to an American researcher at the University of St. Louis, Michael Kinch, the presence of at least some kind of vaccine is needed for mankind to reassure, especially in countries tormented by restrictions. "As soon as such a vaccine is invented and a person is immunized, he will think" finally I can return to normal life", but he will be wrong, because he can still be susceptible to a new infection," says the scientist.

Scientists believe that the coronavirus is spreading asymptomatic carriers of the disease, and fear that as soon as a vaccine that suppresses the symptoms is invented, the number of patients with a new disease will increase. Previously, WHO has denied information that asymptomatic carriers are carriers of the disease. According to WHO representatives, the risk of contracting coronavirus from a person without symptoms is much lower than from a patient with a clear manifestation of symptoms.

Scientists interviewed by the publication say that not all vaccines approved by WHO are equally effective for all people on the planet. With the help of vaccines, it is possible to avoid up to 3 million deaths annually, but 3% of those vaccinated still get sick and can act as carriers of infection.

Earlier, WHO included nine Russian vaccines among the priorities for further research. Russian scientists are currently developing up to one hundred different vaccines, which are at different stages of development: from initial to clinical trials in humans. Most often, DNA vaccines are constructed and a new one from the Chinese virus is developed based on existing vaccines for other viral diseases.
