spidermike007 Posted January 13, 2021 Share Posted January 13, 2021 OK. Now we have yet another vaccine we can avoid, in favor of the ones which are more effective. Why am I not surprised a Chinese vaccine would be less effective? Link to comment Share on other sites More sharing options...
PPMMUU Posted January 13, 2021 Share Posted January 13, 2021 50.4% effective means those who got the vaccine will have 50.4% less chance of contracting COVID-19 than those who did not get the vaccine. Doesn't mean that those who got the vaccine will have 50.4% chance of contracting COVID-19. Link to comment Share on other sites More sharing options...
internationalism Posted January 14, 2021 Share Posted January 14, 2021 about this vax: "Butantan Institute also said the vaccine is 78 percent effective in preventing mild cases that needed treatment, and 100 percent effective in staving off moderate to serious cases – an important part of the story that didn’t make it to many articles translated and published by Thai media.

Nowhere else. And a claim that the vaccine is 100% effective in warding off moderate to serious cases is just not believable. Come up with a better source.
