Okay.. experimental vaccines? There are about 30 different COVID-19 vaccines around the world, with all kinds of different technology. There are inactivated vaccines, live-attenuated vaccines, viral vector vaccines, you name it. And then there are also nucleic acid vaccines, which deliver instructions to our cells, either as DNA or as mRNA. These aren't new, and they have been researched way before COVID-19. It's just that these vaccines save costs and time, which makes them good option for this pandemic. Do note that in less rich and developed countries, more of the other types of vaccines are being used. It's actually a luxury that we can have this type of vaccine and personally I am quite sure that this is the future of most vaccines anyway.
