Mask vs. Vaccine – Which is More Effective?

Currently, mask vs. vaccine is an easy answer. Masks are 100% more effective than something that is not available. Eventually, mask plus vaccine may be the best answer.

According to the evidence, the the masks decrease the amount of virus that is able to be detected on the other side of the mask, regardless of whether the mask is being worn by an infectious person trying to avoid infecting others or the mask is being worn by a healthy person trying to avoid becoming infected.

The dose of virus does seem to matter in transmission of disease.

This does not mean that vaccines will not help, assuming that a safe and effective vaccine is eventually available. The stated cut off level to be applied for approval of a vaccine is currently at least 50% effective. Masks are already more than 50% effective.

“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%,” Redfield said in testimony before a Senate appropriations committee. “And if I don’t get an immune response, the vaccine is not going to protect me. This face mask will.”[1]

That statement was later contradicted by President Trump, but that statement was not contradicted by any credible scientist and was not contradicted by any credible physician. Oddly, the article title suggests that Dr. Redfield walked back his statement, although the article never states that. This may be because the headline is often not written by the person writing the article, but by an editor, looking to get more clicks.

Masks work.

Vaccines are not available and probably will not be available until sometime next year.

If we want the economy to recover, we need to be aggressive about wearing masks to protect others and to protect ourselves.

This is from a paper written in 2009 about influenza, which is transmitted the same way SARS-CoV 2 is transmitted. These were people with influenza, wearing masks, and coughing. The results with an N95 mask and a surgical mask show that both decreased the amount of virus, that would be spread by a cough, to the undetectable level.[2]

Masks do not protect your eyes, so you should consider wearing eye protection. Masks also do not protect your hands, so wash your hands. Typhoid Mary might not have killed anyone if she had washed her hands.
