And this is the problem for us, and why there will be no foreign travel (or holidays) for quite some time. It is fine for the UK to ramp up the vaccines and have 80% vaccinated by the end of the summer, but if the rest of the world is lagging behind, we don't want travelers bringing more covid back. The vaccine stops the illness, it doesn't stop you picking up and transferring the virus to others. What we don't want is someone bringing in a new variant that is vaccine resistant, or a new variant developing here. The more virus in the country, the more chance of it mutating.
