Who will be offered vaccination against covid-19?
People aged 50 years and over will be offered vaccination.
People aged under 50 who are at a higher risk of becoming severely ill from covid-19 will also be offered vaccination against covid-19.
It doesn’t say people under 50 who have had 2 or fewer shots.
The comment you responded to seems to be a partial if not total fabrication.
I don’t see indication of any sort of “roll over eligibility”.
And I don’t think the official recommendation would be 2 shots for everyone since the linked page clearly states it is no longer offered for under 18s, and Søren Brostrøm, director of the health authority, saying it was a mistake to give it to any under 18s, and if you read between the lines and look at the data it was probably a mistake to give it to any under 50s.
