Other experts said that this situation is not only reasonable, but possible.
Shane Crotty, a virologist at the La Jolla Institute for Immunology in San Diego, said: “I fully agree with the overall intellectual concept of the paper.”
Dr. Crotty said that if the vaccine prevents people from spreading the virus, then “it will become more like a measles situation. In this case, you have to vaccinate everyone (including children), and you really I can’t see the virus infecting people again.”
He added that vaccines will prevent diseases more reasonably, but not necessarily infection and spread. This means that the coronavirus will continue to spread.
The natural infection of the coronavirus produces a strong immune response in the nose and throat. However, with the current vaccine, Dr. Gommerman said: “In the actual upper respiratory tract, you will not get a natural immune response, but in the arm you need to be injected.” This increases what happens even after vaccination. Possibility of infection.
Ultimately, Dr. Lavine’s model is based on the assumption that the new coronavirus is similar to the common cold coronavirus. But Marc Lipsitch, an epidemiologist at the Harvard Chenchen School of Public Health in Boston, warns that this hypothesis may not hold.
Dr. Lipsitch said: “Other coronavirus infections may or may not be applicable, because we have not seen what effect those coronaviruses can have on older, naive people.” (Naivety means that their immune system has not been exposed to it. Viral adults.)
