Russian authorities have approved a light version of the Russian corona vaccine Sputnik-V.
With this variant of the drug, you are already protected against the coronavirus after one shot instead of two.
The vaccine is said to be nearly 80 percent effective. That is slightly less than the regular variant of Sputnik-V, of which you need two doses.
Russia mainly wants to export the light version to other countries where the number of infections is very high to make people less susceptible to the virus as quickly as possible.
A dose of the vaccine will cost less than $ 10.
