Travel after COVID vaccination

[piccalilliplease]

Anyone wondering how the COVID vaccine will effect travel in 2021?
I'm imagining it might be like a Yellow Fever vaccine, that a certificate is an entry requirement. If that's the case then private clinics will be desperately trying to buy stock.
But if we don't know how long immunity from the shot lasts then maybe there's little value in it.

A lot of countries at the moment require a certificate that visitors are not infected - not available on the NHS & I believe c.£200 privately.

I do hope that when the vaccine is rolled out, certificates of vaccination are provided f.o.c.

I wonder if that a vaccination certificate could be supplied instead of a negative swab result.
I haven't read anything about certificates so far.

They do, and even then dependant on destination it is possible the test may not allow you to hop off the aircraft/boat and go roaming around the countryside.

Even though you've been tested in the UK some countries then test you again on or just after arrival, and place restrictions on your movements (e.g; confined to hotel or other accommodation) for some time after arrival..

A universally recognised vaccine is very much needed.
