Two doses of the polio vaccine are 90+ percent effective. Two doses of the Moderna/Pfizer COVID-19 vaccine are 95+ percent effective against any illness at all and 100 percent effective against severe illness. If the polio vaccine is your goal, it's been surpassed.

- stevenicr 6y agothanks for the clarification - I had not known polio was only at 90% - since it has been all but eradicated (?) I had assumed it was 100. I worry many others assume similar - as going back to an office with all at 80-90% I would do, but I may skip the shared bathrooms if I was really worried about it.
