The formula is expected to be delivered on Monday, said Russia's Health Minister Mikhail Murashko. "The first small batches have already been shipped," Murashko said, explaining that the government is testing the supply chain to ensure a robust delivery system across the country's 85 regions. As well as testing the efficacy and safety of the vaccine itself, the government believes it is paramount to ensure the efficient distribution to citizens, especially to those at high risk. 

Russia's homegrown Covid-19 formula is currently in the third and final stage of clinical trials, in which 40,000 Muscovites will take part. While three-quarters will receive the jab, another quarter will be given a placebo. On Wednesday, Moscow's Deputy Mayor Anastasia Rakova announced that testing had begun, and over 35,000 residents had applied.
