As Paralel.az reports, a new, fourth wave of COVID-19 occurs in Europe simultaneously for several reasons: “The main reason is that part of the population refuses to be vaccinated. Without vaccination, the quarantine regime will operate throughout Europe. The main problem remains the population, which for various reasons refuses to vaccinate.
Another reason for the increase in the number of coronavirus infections is the time factor, since more than six months have passed since the vaccination, and the immune system has weakened.
Among the factors contributing to the spread of the coronavirus is the more aggressive Delta variant, which dominates European countries.
