A vaccine candidate that was rejected in Kenya could be made commercially available mid next year if trials elsewhere find it effective. British drugmaker AstraZeneca will manufacture millions of doses of this vaccine candidate in anticipation of it proving to be both safe and effective. The WHO data also discounts claims that Russia has successfully completed clinical trials of the world's first Covid-19 vaccine. The WHO indicates the Russian vaccine candidate as a Phase 1 trial, that still needs to undergo Phase 2 and Phase 3. According to the WHO, the earliest the world can expect any Covid-19 vaccine is mid-2021, but even that is not assured.
