“Most of the people who get infected during the fourth wave of Covid-19 will probably be unvaccinated young people because the older people are now vaccinated,” Prof. Soren Hayrabedyan, immunologist at the Bulgarian Academy of Sciences’ Institute of Biology and Immunology of Reproduction said in an interview for the BNR’s Horizont Chanel.
In his words, what surprised experts is the large number of hospitalized young people – a fact showing that infection with the Delta variant causes more severe disease. The principal difference between the unvaccinated and the vaccinated if they contract Covid-19 is that with the former, no antibodies are formed even during the second week after infection, whereas with vaccinated people a re-formation of antibodies begins right away and they have an additional level of protection, Prof. Soren Hayrabedyan says, and adds that that there are no medical grounds to fear vaccination.
