CDC director says 'masks are more guaranteed to protect you from COVID-19' than a vaccine

'I might say this face mask is more guaranteed to protect me against covid than when I take a vaccine' Dr Robert Redfield said before a Senate committee. Wearing a face mask has been shown to cut a person's risks of contracting COVID-19 by up to 65% and coverings reduce the spread of infectious particles. It remains unclear how much protection a coronavirus vaccine will offer. FDA regulators set the minimum efficacy for a shot they would approve at 50%. Some people may not have an immune response to a future vaccine - and there is not yet substantial data on shots because they are not yet in use. It comes as a CDC 'playbook' said federal agencies plan to distribute a COVID-19 vaccine broadly and for free to Americans by January.
