The Sputnik vaccine is under “rolling review” by the European Medicines Agency along with 4 others which doesn’t include the Valneva vaccine. The last update from EMA regarding Sputnik vaccine was March 2021 where they stated it was under rolling review. Apparently Russia’s Gamaleya National Centre of Epidemiology and Microbiology who developed it are not accustomed to dealing with the requirements of such a regulatory agency. Or perhaps the EMA is dragging its feet, who knows?
Regarding Valneva Javid said this in parliament: “There are commercial reasons that we have cancelled the contract, but what I can [say] is that it was also clear to us that the vaccine in question that the company was developing would not get approval by the MHRA here in the UK……..”
“I think there had been some talk of people who had the Oxford for their first jab being offered Sputnik as their second?”
I think this may have happened in Argentina due to shortage of the Astrazeneca vaccine for second doses but it’s not approved in the UK for use. The Ministry of Health of Buenos Aires province published a Lancet article:
“Sputnik Light has shown efficacy of 82.1 to 87.6% against hospitalisations. The component of Sputnik V has shown 78.6 to 83.7% efficacy among elderly people aged between 60 to 79 years.”
