Assuming you aren’t living like a hermit.
The UK is averaging 22,000 infections assuming this stays the same. There is 67 days until end of year. This is 1.4million infections.
Given that it is likely cases will grow. It is likely many millions will be infected.
Say infections stay the same and a vaccine isn’t available until 1st of March. This is 3 million.
This is all assuming cases don’t rise. Which they will and is not taking account of asymptomatic infection.
We might as well except the inevitable that we will likely contract covid and get on with our lives.
