Millions and millions of people die of different reasons not related to covid every year and no one bats an eyelid. Sure, if some people want to stay home waiting for 110% of the world population to receive 10 vaccines against covid they are free to do so but just don't expect everyone else to put their lives on hold indefinitely. Children won't need mass vaccinations as far as I can tell based on various experts, or at least it certainly won't happen anyway for various reasons, not for many years at least. It is not the fear of disease that is keeping people off traveling but the restrictions and inconvenience. Without them I would live my life as normally as ever and I see many many people feel the same.
