The Department of Foreign Affairs says it is aware of the situation.
Im trying to figure out the case mentioned further down in the article
One passenger, who has a DCC but whose girlfriend does not, told The Journal that her HSE vaccination cert was not accepted when the couple landed in Malta. This is despite her HSE certificate being checked before she boarded the flight in Dublin.
In the comments people suggest she tried to pass off the hse vax card as proof rather than a DCC which she did not have.
Sounds like to me a few chancers here who did not pre prepare properly and this is the result, regardless of what they thing the gov said or not. If you are travelling abroad in these times you really have to be well prepared and all the i's dotted before you go. Playing the victim card in my view is not an option
