China is one of the front-runners in the global race to develop a COVID-19 vaccine. Around eight different vaccines are said to be under clinical trials but none have so far been approved for the market. Russia registered its first vaccine candidate Sputnik V developed by Moscow's Gamaleya Institute in August. But China claimed that it has been administering its domestically-developed COVID-19 vaccines to a broad range of people including medical workers the armed forces and employees of companies who are working overseas since July 22. Now the country has approved its first nasal spray COVID-19 vaccine for clinical trials.
