The new rules refer only to travelling within the European Union. However, the Commission recommends that EU countries also apply them on national levels, to provide “certainty for travellers and reduce disruptions.”
If you’re an EU resident, the Commission recommends that you receive a booster shot six months, at the latest, after being fully vaccinated. That being said, the certificate will be valid for three additional months as a grace period to ensure access to booster doses, hence why the certificate is valid for nine months, as opposed to six.
Following a booster shot, the validity of the vaccine passport will be extended. At the time of writing, there is no limit on the validity, as there is a lack of scientific evidence regarding the duration of protection from booster shots.
The EU Commission also introduced a new rule referencing the recording of the booster shot in vaccine passports. Booster shots following a two-dose vaccination should be recorded as 3/3 on the certificate. A single-dose vaccination followed by a booster, on the other hand, should ready 2/1.
The rule can be blocked by a qualified majority of EU governments, or a simple majority of European Parliament members. However, officials believe it has enough backing.
Thus far, 807,000,000 COVID vaccine certificates have been issued within the European Union.
