For foreign travel I can see vacine passports happening but how many UK businesses would actually want this?
They would be turning away potential business (especially true if you cater for the young) there would be the extra costs of hiring staff on the doors to check vacine passports and the praticality of enforcing it? It may be affordable and suitable for the big supermarkets but not so much for the local bookshop etc.
I would like to say none, but given how enthusiastic some local businesses here were about checking temperatures on entry I'm not so sure. Some businesses seem to like Covid theatre and are happy to go far beyond whatever government rules and guidelines are in place.
In reality I cannot see it happening domestically. In the short term, not enough people will have been vaccinated so it would mean shops turning away most of their customers. I doubt many hospitality businesses would survive if their customer base was limited to over 60s, health care workers and those vulnerable to Covid.
Meanwhile this would be incredibly unfair to the younger people who, by and large, have followed restrictions for the last 12 months to protect the above groups rather than to protect themselves. It is right that the vaccines are distributed based on risk, but it is wrong that those who are deemed lower risk face more restrictions.
So in the short term I am convinced that such a policy domestically would be impossible to implement.
In the longer term, hopefully it will not be necessary - the vulnerable will be protected, the vaccines should significantly reduce the rates of infection and we will have to live with the cases that remain. Nobody has ever suggested checking for flu vaccines before allowing entry to venues - Covid should be no different.
For international travel it's a bit different because it's not down to the UK Government, it's the overseas government. So I can see we may need to introduce some form of document to enable British Citizens to travel to countries where it is required. Even then though, I think it will be a bit like quarantine, where countries will apply different rules based on the infection rates in the country that the traveller has arrived from.
