The interval between the administration of the first and the second dose of the Sputnik V vaccine against the coronavirus may be up to two months, Alexander Gintsburg, Director of the Gamaleya National Research Center for Epidemiology and Microbiology of the Russian Healthcare Ministry that developed the vaccine, said in an interview, APA reports quoting TASS.

"According to the manual, [the interval should be] three weeks. Yet, based on research data and observations, if the interval for some reason has been increased to two months, this won’t be crucial in terms of effectiveness," he said.

In response to a question whether a person should repeat both shots if he got sick after receiving the first dose of the preparation, the scientist said that one shouldn’t get inoculated all over again. "Yet again, it is necessary to determine the individual’s titer of protective antibodies and decide, depending on this, whether to inoculate him with the second component or not," he explained.
