Infectionist Timakov called Sputnik V the most effective for revaccination against coronavirus 
the most effective drug for revaccination against coronavirus.
According to the specialist, any Russian vaccine can be revaccinated against COVID-19, but he called Sputnik V the most effective, as it prevents severe disease, death and the disease itself.
“There will be no side effects, the two platforms can complement each other. Scientific data on this have not yet been published, research is underway, “the specialist explained.
According to Timakov, foreign studies show that a combination of various vaccines is effective in preventing infection, combined immunity can more actively form virus-neutralizing antibodies.
Earlier, an expert from the World Health Organization (WHO), Professor Santiago Mas-Coma, in an interview with Lenta.ru, advised to undergo revaccination with the third dose, since the immune protection after vaccination against coronavirus lasts only a few months. He clarified that it is best to revaccinate with drugs modified to combat new strains, including the delta variant; mRNA vaccines are easiest for this purpose.
