Your articles on the possible prevention or treatment of infection in the covid-19 pandemic have been interesting, but none have mentioned whether it is worth investigating the protective effects of applying any of the numerous veterinary vaccines against other coronavirus diseases to people.
We now require very substantial quantities of vaccine as soon as possible in order for them to be effective at the population level. If any of these veterinary products can be effectively adapted, we might be able to greatly reduce the vaccine deployment time, compared with developing one from scratch.
