When you consider the medical impact Covid has had on the world in terms of infections, deaths, long-term health effects (still unlikely to know anywhere like the full extent of this).
Then think about the effects on the economy, jobs, livlihoods, people’s businesses.
Then consider the mental health effects that it has caused. People losing loved ones, pressures of lockdown, unemployment etc.
The impact on schooling and education on our children.
This is being felt all over the world. In almost every country. I think the concept of vaccine passports is a good thing if countries can protect themselves when we get out of this mess. Why expose your country to the risk of this again because someone doesn’t want to take a vaccine? Every country will have their own populations who refuse the vaccine and you run the risk of these people all getting ill / spreading the virus again if it gets back into your borders.
People have a choice - nobody needs to travel anywhere for a holiday.
