Sputnik V makers propose AstraZeneca combination
Developers of the Russian-made Sputnik V vaccine suggested that AstraZeneca plc combines its two full doses jab regimen with Sputnik V "human adenoviral vector shot to boost efficacy."
"Combining vaccines may prove important for revaccinations," Russian developers stressed in a tweet posted on Thursday.
The two full doses regimen of the vaccine developed by AstraZeneca and Oxford University showed only a 62% efficacy, compared to 90% when a half dose was followed by a full dose at least a month later. On the other hand, the N. F. Gamaleya Federal Research Center for Epidemiology and Microbiology said that its Sputnik V vaccine was over 95% effective 42 days after the first dose, or 21 days after the second one.
