Regarding "Going out? Here's where proof of vaccination is required in the St. Louis area" (Sept. 9): I suggest that more organizations and venues require proof of vaccination or a negative coronavirus test before entry.
Currently, many music venues in St. Louis have initiated this policy. Perhaps this would also be a great policy for entrance into all major sporting events, museums, cinemas, casinos and any other venues where unvaccinated people, by their choice, are endangering all the others around them.
