An anecdote in the other direction: I know people that were working in the hospital, treating COVID-19 infected people, before vaccines. Protection was a N95 mask (well-fitted and tight), a gown and gloves. They worked for months without an outbreak, until a bunch of them got infected. The source of that infection was probably in a meeting with a patient (for things unrelated to COVID) in a closed room when they were wearing non-N95 masks. None of them had strong symptoms other than a few days feeling awful. > Maybe Pfizer should go back to the drawing board. Maybe we should look at the data and see that the vaccines are still pretty effective. Think about the difference in restrictions and people behavior between now and before the vaccines: they have pretty much enabled normal life again and made COVID a much less worrying disease, even with high case numbers again.
