To be honest even the 10 day UK quarantine with day 2&8 testing rules out all but essential trips, since most of us can't get more than 2 weeks off work, and the PCR tests add another £200 per person to the cost of the trip.
Hopefully there will be some sort of vaccination passport scheme coming later in the summer - yes I know that vaccination is not proven to eliminate transmission, but current evidence indicates that it greatly reduces transmission. At some point governments will have to allow vaccinated people to travel more freely, or else we could have many more years of greatly depressed international travel. (Yes I know that would be good for the environment, but some of us have family abroad, some of whom are elderly).
