I wanted a holiday in Spain in 1978, if I didn't have a yellow fever vaccine, I couldn't go on holiday. It didn't matter which government was in power, I didn't question the reasons why I required the vaccine. How times have changed, people now say it's their Human Rights to do as they please and ignore government advice. If people need to fly abroad then it's right they should have proof of having a Covid vaccine, I am sure the country they were flying to would think so as well.
