WASHINGTON—The Food and Drug Administration released guidance Tuesday outlining its conditions for approving a Covid-19 vaccine, including a requirement that any vaccine be at least 50% more effective than a placebo in preventing the disease.
The FDA said that no vaccine would be approved unless a vaccine company had “clearly demonstrated” proof of a vaccine’s safety and effectiveness through a clinical study, according to the guidance.
The Trump admin's next debacle! A vaccine that does nothing, or worst. They could have contributed to the effort to assure success. Trump has squandered all the power of the office that could have made a difference. Trump must go!
LOL. Only 50% effectiveness. Here's something that's % effective: a good immune system!
Low bar. What’s 50% more than zero? Clinical and analytical background noise is the answer.
Only 50%?!?! A vaccine is supposed to be 90% effective or better
What’s 50% more than 0?
Don’t count on me to use any of the “fast track” anti-SARS-CoV-2 vaccine being developed with $$$ in mind rather than saving people. Only when Israel & France come with a vaccine developed the right-way and proven effective and safe, will I use it. In mean time, lockdown for me
Flu vaccine is only 50% at best. So It should be at least that.
should 60% 50 is borderline 🧤😷
Testing a vaccine!! ajwahls
What’s 50% of zero?
Yeah, whatever, I don't trust anything not a single thing coming out of this administration. They're just treasonous grifters fleecing America right before our eyes and laughing all the way to the bank with the taxpayer's money. Criminals GOP.
