Due to studies as the recent one by Imperial College that shows that the COVID-19 immunity acquired by the cured people falls quite quickly, reported O Globo, and a second wave of the disease already sweeping Europe, Russia applied to WHO on Tuesday for a license for the emergency use of Sputnik V, its most advanced testing vaccine, according to Reuters.
In Brazil, there are two initiatives to produce the Russian vaccine. The pharmaceutical company União Quimica signed an agreement with the Russian Direct Investment Fund (RDIF) to produce it starting in the second half of November and the government of Paraná has a partnership to test and produce this vaccine.
Russia was the first country to grant regulatory approval to a vaccine, and did so before large-scale trials were complete. WHO has not yet given a deadline to respond to the Russian request.
