The endpoint of the Roadmap is, among many other things, to introduce a "common vaccination card/passport" for all EU citizens.
This proposal will be appearing before the commission in 2022, with a "feasibility study" set to run from 2019 through 2021 (meaning, as of now, it's about halfway through).
To underline the point:
The "vaccination roadmap" is not an improvised response to the Covid19 pandemic, but rather an ongoing plan with roots going back to 2018, when the EU released a survey of the public's attitude toward vaccines titled "2018 State of Vaccine Confidence".On the back of this research, the EU then commissioned a technical report titled "Designing and implementing an immunisation information system", on - among other things - the plausibility of an EU-wide vaccination monitoring system.
