Dr. Robert Redfield
The US-based Centers for Disease Control and Prevention (CDC) has said face masks may provide better protection against COVID-19 than a vaccine.
CDC Director Dr. Robert Redfield made the statement during Wednesday's Senate Appropriations sub-committee hearing.
"I might even go so far as to say that this face mask is more guaranteed to protect me against COVID than when I take a COVID vaccine because the immunogenicity may be 70 per cent, and if I don't get an immune response, the vaccine won't protect me, this mask will," he declared.
He went on to urge Americans, particularly those 18 to 25 years old, to be vigilant and take responsibility "because we haven't got the acceptance to personal responsibility that we need for all Americans to embrace this face mask."
