CV 19 Vaccination Certification?

I would imagine that as long as one has had an approved vaccine, that would suffice anywhere you wanted to go. I can envisage a certificate/signed doctors letter system (both physical and electronic) in place for insurance and travel purposes. 

Vaccination from the free but have to pay doctor for  certificate. 

Yes.  I expect the exchange of money will be required at some point .

As we've ventured further afield over the past 10 years or so, we've required any number of extra vaccinations which we get from the travel section of our local surgery. Each has been documented in a "travel passport" so I would have thought it possible to do similar for Covid. Undoubtedly, though, HMG will be looking at ways of turning it into a revenue raising exercise! 

“Undoubtedly, though, HMG will be looking at ways of turning it into a revenue raising exercise!”

Personally, I don’t have a problem with that, given that this country now has a mountain of debt. I’m sure we’ll see lots more in the future.

I travelled extensively and had so many vaccinations that my vaccine passport ran out of space. I recall that certain countries required proof of vaccination  (e.g. Yellow Fever) but not in the West and I can’t see that proof of a COVID vaccine would be required in Europe. Apart from anything else, the vaccines have limited effectiveness and are no absolute guarantee of protection.

Fortunately there are several if not many candidate CV19 vaccines.  All are slightly different and it would appear that at least one may be effective at preventing the those infected passing it on.  That is a wonderful bonus but could be a double edged sword if some countries start requiring visitors to have it to protect their population.

To my knowledge, the vaccines that have been developed so far have, up to now, only been shown to be effective in protecting the person who has been vaccinated. There is, as yet, no data to would indicate that the vaccine prevents anyone from passing the virus on to someone else. Whether a certificate may be necessary will depend on the outcome of further investigations in that direction.

The Novavaz vaccine is showing promise in that some early trials have indicated it may prevent onward transmission of the virus.  Still a long way to go though.

I would be very surprised if a certificate becomes mandatory. If you look globally I think it is only Yellow Fever in a limited number of countries that requires a certificate as a condition of entry.
