According to one website I read (The Local IT), the Italian Health Minister said you will only need ONE of the following to travel to Italy as of March 1:
1) Vaccine Card
2) Proof of Recovery
3) Negative Test Result
Has not been made official yet - but being reported on-line...
One additional item to note - you still need to have a vaccine card (meeting the current parameters for timing of shots) to go into museums, restaurants, bars, etc. So traveling unvaccinated will really limit access once in country.
