Why did CDC director say masks are more of a guarantee against COVID-19 than a vaccine?
The director of the Centers For Disease Control and Prevention caught many people off guard when he said masks are more of a guarantee in the fight against the coronavirus (COVID-19) than a vaccine would be. โI might even go so far as to say that this face mask is more guaranteed to protect me against COVID-19 than when I take a COVID-19 vaccine,โ Dr. Robert Redfield said. He was referring to the fact that experts donโt expect the COVID-19 vaccine to be 100% effective. Experts, including Redfield and Dr. Anthony Fauci, hope the vaccine will be at least 70% effective. โThe immunogenicity may be 70%, and if I donโt get an immune response, the vaccine is not going to protect me,โ Redfield said.
