The program sounds good on paper. There is supposedly some certification requried to go maskless with a vaccinated staff and all customers, and also follow up audits, but it will be an overwhelming task to enforce.
I am due for an elective surgery and time will tell whether the medical system by that time will be overwhelmed because the same people who take anti-depressants, statins, blood pressure medications, and other medicines all with risk of adverse effects refuse a covid shot because they've read an article, heard a podcast, or talked with same minded friends. I think it is a cultural issue more than a scientific one.
We can go back and forth about masks and I have an opinion, but people just need to get vaccinated. Until that happens, the beatings will continue until the attitude improve. The second line of defense is restrictions on mask and social distancing whether you or I like it or not. I believe as one of the German health officials said, eventually everyone will either be vaccinated, cured, or dead. I would add, or combinations there of.
