If there is no vaccine we'll live with it. As said there are lots of diseases, especially flu variants, where there is no effective vaccine and we survive. Well lot's of us do - remember something like 15000 died in the UK in early'10's from flu and there was no big fuss. CV19 is more transmittable than normal flu but a lot less than something like measles. It kills a small percentage of people who catch it - and it's clear these are mainly a) people with existing problems b) the aged
An Italian doctor said a month ago "this disease - it largely kills people today who would have died next month; it kills people next month who would have died next year"
Its not nice but it's not the end of the world - anyone under 30 has more chance of being killed in a accident I think
