The globe is racing for COVID-19 vaccine trails. In principle, it takes more than 8 years for a vaccine to go through all the pre-clinical and clinical trials before implementation. But there are now about 10 vaccine candidates that have started Phase 3 clinical trials - the final step to prove its effectiveness and safety before seeking regulatory approval.

According to CCTV News on September 22, local time 21, the World Health Organization Director-General Tedros Adhanom Ghebreyesus said at a regular press conference that there were nearly 200 COVID-19 vaccines in clinical or pre-clinical trials worldwide, but not all of them will be developed successfully.
WHO is working on the COVID-19 Vaccine Implementation Plan, which is expected to deliver 2 billion doses of COVID-19 vaccine by the end of 2021. The goal is to ensure simultaneous access to COVID-19 vaccine in all countries, with priority given to high-risk groups such as health workers and the elderly.
Mr Tedros said the more candidates there were, the better the chance of a safe and effective vaccine. This was not about charity, he said, but in the best interests of each country. The quickest way to end the COVID-19 pandemic and accelerate global economic recovery was to ensure that people in all countries can be vaccinated against the coronavirus, not all people in some countries.
Dr Soumya Swaminathan, WHO chief scientist, said that China's COVID-19 vaccine research and development program was very active, and there are several vaccine candidates in the advanced stage of clinical trials. The WHO was interested in China's COVID-19 vaccine and had been closely watching it, and some vaccines had been shown to be effective in clinical trials at this stage.
