Two Russian Covid-19 vaccines have been registered for use even prior to clinical trials were completed, but have not been extensively accepted outside of Russia.
The Phase 3 medical trial– the last– of the new vaccine, BNT162b2, started in late July and has actually enrolled 43,538 participants to date, 90 percent of whom have gotten a second dosage of the vaccine prospect since November 8.
