"The effectiveness of the vaccine is made up of its immunological effectiveness and preventative effectiveness", the TASS news agency reported, citing Rospotrebnadzor.
The vaccine distribution plan was presented during President Andres Manuel Lopez Obrador's daily morning news conference as he seeks to promote the government's commitment to speedy delivery of four vaccines.
The vaccine's use was initially approved by the Health Ministry on December 23, a day before the first batch of 300,000 doses arrived in the country from Moscow.
Dmitriev also took aim at what he called "information attacks" against the vaccine, pointing to previous media reports that Hungary wasn't intending to actually use the shot.
Prime Minister Viktor Orban has complained that Hungary was not receiving enough vaccine doses through the EU.
Merkel said Germany's Paul Ehrlich research institute could help guide Russian Federation through the European Union approval process. Hyderabad-based Dr Reddy's is conducting trials of the vaccine in India and went into phase 3 trials earlier in January.
The application for approval was submitted to the European Medicines Agency (EMA) by the Russian Direct Investment Fund, which has supplied part of the financing for the vaccine and is marketing it overseas.
"The price of Sputnik V is less than United States dollars 10 per shot, making it affordable around the world".
The vaccine's speedy approval was highly controversial.
Scientists have raised concern about the speed at which Moscow has launched its vaccine, giving the regulatory go-ahead for the shot at home and launching mass vaccinations before full trials to test its safety and efficacy had been completed.
Russian Federation has commended the decision of the UAE Ministry of Health and Prevention (MoHAP) to approve and register Russia's Sputnik V COVID-19 vaccine for emergency use.
The data, based on Phase I and II trials, were released before the start of a larger Phase III trial which would normally involve thousands of participants and a placebo group as a comparison.
