We Need to Wear 2 Masks

Its hard enough to get people to wear one mask. Now medical experts are saying two masks will provide a higher level of protection against the new variants that have emerged. Since 95 masks are being reserved for medical personnel, there is the KN95 that is not medical grade but suppose to do the trip. How about it someone develops a mask that will serve the purpose required. Once vaccinated we will still be wearing mask. Statistically we need 70 to 80 percent to reach herd immunity, and currently 1 out of 4 people indicate that they will not get the vaccination.
