This will depend on the duration of immunity in those who have had COVID-19 and in those vaccinated. “It’s one thing if for a year or two, and if it is less, it will mean that virtually the entire population will need to be vaccinated again,” Sergeev said. The head of the Russian Academy of Sciences also noted that in the fight against coronavirus, most likely, one will have to rely on approximately the same tactics “which we have been conducting for decades with regard to influenza.”
