I stumbled across the following when I was looking for something else:

BRUSSELS, Jan 15 (Reuters) - The European Commission is working on a vaccine certificate, dubbed “Vaxproof”, that could help restore cross-border travel, EU officials said, but the plan is dividing EU nations.
The issue has been discussed for months but has led to no compromise because of fears over vaccine hesitancy and privacy.
The EU executive Commission is working on a system for mutual recognition in all 27 EU countries of a certificate proving the holder has been vaccinated against the new coronavirus and therefore needs to undergo no tests on arrival to another country, according to two EU officials briefed on the matter.
The article goes on to discuss the proposal in the context of high levels of vaccine hesitancy in Europe, and how this may be perceived as edging towards coercion for the hesitant.
I have no reason at all to doubt Reuters as a source, but if you google vaxproof you don’t get many hits, and I couldn’t find any for the EU Commission.
