It's great that you are considering a trip to Ireland! ☘️
Since yesterday March 6, you can visit the Republic of Ireland without the need for proof of vaccination, recovery or a negative PCR test. You can find more information on the government website
still requires a pre-departure and post arrival test if you are not fully vaccinated.
I'd suggest you keep an eye on official sources to make sure the information is up to date.
I hope this helps. 😊
