A flu-like syndrome, including elevated body temperature, has been observed after inoculation with the Sputnik V vaccine against the novel coronavirus infection in about 10% of volunteers, APA reports citing TASS.
No serious adverse reactions after administering the preparation have been detected, Sergei Glagolev, aide to the Russian health minister, reported on Tuesday.
