It isn't a vaccine... market it however they want, its just a suppressant. Better to just catch the original virus, build immunity naturally and not deal with unknown long term side effects.
1.) If you define "vaccine" as
using dead or weakened viruses to get the recipient's immune system to produce antibodies against the target virus, then none of the vaccines currently approved or in final test stages for use in the US are vaccines. OTOH, if you define "vaccine" as as substance that causes the recipient's immune system to produce antibodies against the target virus, then all of the vaccines currently approved or in final test stages for the US are vaccines.
a. What's the point of the hair-splitting word game? A vaccine by any other name produces the antibodies and consequent immunity.
b. Ask Chile and Brazil how Sinovac's traditional weakened virus vaccine is working out for them!
2.) Re what I bolded, BTDTGTTS.
After two weeks in bed in the hospital and two months (so far) working to rebuild my strength and endurance, I'd take any of the vaccines currently approved for use in the US. I survived and wasn't on a respirator, but I can ask a friend's wife about that latter experience; people who experienced the former are unavailable for comment, this side of eternity. Make your choices as to the risk you're willing to assume, but don't deceptively tell others that the significant risks entailed in getting Covid are negligible.
