"At the moment, three more vaccines are being registered," Murashko told reporters.
The minister added that these were both, domestic and foreign developments, the production of which would be carried out in Russia.
Earlier in the day, Russian President Vladimir Putin said in an interview with the Rossiya 24 broadcaster that a second Russia's vaccine against COVID-19 will be ready in September.
He expressed hope that the new drug will be as effective as the first vaccine, which was registered in Russia on 11 August.
On Tuesday, the Gamaleya Research Centre, which developed the vaccine jointly with the Russian Defence Ministry, received permission to conduct post-registration clinical trials of the coronavirus drug.
