https://www.covid-19vaccinetracker.org/we can see here that only 3 vaccines are authorized, the rest still have to go through phase 3. There are still many people in the world who are skeptical about the effectiveness of vaccines, I respect their fears but IMO is better at vaccines than lockdown again.
The WHO has authorized only 3 vaccines. But 7 others have been issued EUA (emergency use authorization by various countries). And yesterday, the reputed medical journal Lancet published peer-reviewed result of the Phase III trials of Sputnik V vaccine (being developed by the Gamaleya National Center of Epidemiology and Microbiology in Russia). They have announced that the vaccine has shown a net efficacy of 92% during the Phase III trials.
