Experts are still arguing on when the first wave of COVID-19 actually ended in Ukraine and the second began, and whether the latter started at all.
Doctor of Medical Sciences Iryna Kolesnikova says vaccination against COVID-19 will show its effectiveness in April-June, as reported by the RBC Ukraine news agency.
Experts say Ukrainians will be undergoing vaccination from mid-2021 to the end of the year.
"I think that vaccines will work, and the viral infection will go on decline starting 2022," Academician Serhiy Komisarenko said.
At the same time, other scholars don't rule out a more realistic scenario, namely if Ukraine receives the vaccine only in the third quarter of 2021.
The ascertainment rate of COVID-19 will start declining before July 2022, provided that vaccinations actually launch in Ukraine at least in the autumn of 2021.
