I have massive reserve for Russian vaccine. China sinovac vaccine efficiency is validated by third party in big country like Brazil with high level cases of covid-19. So the vaccine result can be internationally trusted. It has already approved by Brazil and many countries. It is the most trusted vaccine after Pfizer and Modena.There are more options. The Russian vaccine, for example.
Other than that, Iran already has a vaccine that is undergoing human trials at the moment. The third group of volunteers were vaccinated today. We also have 7 other potential vaccines in line that 3 of them will undergo human trials soon.
