None of the COVID-19 vaccines so far has completed the Phase III trial, which is mandatory for a vaccine to be rolled out in the market.
On August 11, the Russian government announced that they have first registered the COVID-19 vaccine in the world. The vaccine has Registered after less than two months of human testing (Phase I and Phase II). The final stage of clinical trials to test the vaccine's safety and efficacy will continue in collaboration with India. Many scientists raised questions about the vaccine's safety and effectiveness.
Later on September 16, the Russian Direct Investment Fund (RDIF) announced that Russia collaborated with Indian pharmaceuticals major Dr. Reddy's Laboratories to conduct Phase III clinical trials and distribute the COVID-19 vaccine named 'Sputnik V.'
According to the World Health Organisation regulation, a promising candidate's clinical trials are bound by strict regulations and take place across three phases to get approval for the use of a vaccine. Moreover, around the globe, many scientists are in the race to find the vaccine for COVID-19, and few vaccines are listed in the Phase III trials, but none have received WHO's approval.
So far, there is no vaccine ready to treat COVID-19 as the WHO has not approved any drug and has repeatedly said that all vaccine candidates should go through full stages of testing before being rolled out.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
