The ministry on Tuesday published the fourth version of guidelines for organizing medical care for pregnant women and newborns with coronavirus.
"At the pregnancy planning stage, it is important to get vaccinated. We emphasize that there is currently [no] data on the negative impact of COVID-19 vaccines on the reproductive function of men and women," it said.
"Domestic vaccines are safe, whereas coronavirus infection itself can have a negative impact on the reproductive function," the ministry said.
Earlier, the Health Ministry's Endocrinology Research Centre said that Russia's Sputnik V vaccine has no negative effect on male reproductive health.
The Gamaleya research center, which developed Sputnik V, said in December that there was no evidence linking the vaccine to infertility in either men or women.
