“It is absolutely certain that vaccines prevent an increase in the number of cases of severe disease and deaths from the“ delta ”variant,” TASS quotes her.
At the same time, WHO expert Maria van Kerkhove added that even in those countries where the level of vaccination is high, the "delta" circulates in those communities where there are fewer vaccinated people and where measures to prevent the spread of the disease are not followed.
Earlier, WHO Director General Tedros Adhanom Ghebreyesus spoke about the situation with the spread of the "delta" strain of the COVID-19 coronavirus infection.
