COVID mutations cannot affect the vaccine’s effectiveness, said Alexander Gintsburg, head of Russia’s Gamaleya Center.
If mutations are observed in the future, this will be a reason for experimenting and testing the existing vaccine, he noted.
This won’t be a fundamental point in terms of the vaccine’s effectiveness, he said on the air of the Rossiya 24 channel.
He also added that constant monitoring of COVID-19 strains is a necessary attribute of a competent long-term policy.
US Ambassador to Russia John Sullivan turned down Moscow’s offer of a Christmas COVID jab, noting that there are already two US-made drugs on the market, NEWS.ru reported earlier.
