How about in order to go and see needy clients who had asked for help from the charity for which I volunteer? Some of these were classed as vulnerable and, in order to meet insurance requirements, we were instructed that we should be vaccinated otherwise, like many health workers, we would not be allowed to give assistance. I am now 76 years old and still help those in need, if I drop dead tomorrow ---so be it -----but I shall miss my holiday. >;)
