'Will not save you from infection': the rush to create a vaccine against coronavirus can affect its quality
Desperate attempts to keep the economy afloat and to create a vaccine against coronavirus as soon as possible can lead to the fact that the drug will be weaker than it could be. Writes about it Fox News.
According to Bloomberg, although a “knockout punch” vaccine would be ideal, early vaccines may have a limited spectrum of action, said Robin Shattock, a professor at Imperial College London, who leads the development of an experimental vaccine.
"It is not yet clear whether this will be protection from infection or protection from disease," Shattock said. "It is possible that a vaccine that only protects against serious diseases will be very helpful."
"Vaccines are supposed to protect against disease, not infection," said Dennis Burton, an immunologist and vaccine researcher at Scripps Research in La Jolla, California.
Such a vaccine can improve the situation in areas tired of quarantine.
“I guess the day after someone is immunized, they will think, 'I can get back to normal. Everything will be fine, ”said Michael Kinch, deputy vice president of the University of Washington in St. Louis. "They don't necessarily realize that they can still be infected."
The Office noted that few, if any, vaccines are 100 percent effective for all recipients. On June 9, the World Health Organization (WHO) listed 136 vaccine candidates, 10 of which are undergoing clinical evaluation.
According to Michael Felberbaum, spokesman for the Food and Drug Administration, the agency could potentially consider vaccines related to the prevention of serious illnesses if the evidence confirms the benefits of vaccination. According to him, to obtain a license for a vaccine does not require a confirmed action of protection against infection.
For example, in a June 11 update from Moderna, Inc., the company stated that the primary endpoint of the late-stage study is the prevention of symptomatic COVID-19 disease. According to Kinch, "there will never be a truly perfect vaccine," but imperfect but practical vaccines can be observed.
