MILAN—Italy’s health ministry has recommended that people with a severely compromised immune system receive a fourth mRNA vaccine shot against COVID-19, provided that at least 120 days have passed from their previous booster, it said on Sunday.

The special commissioner appointed by the government for the COVID-19 emergency will set the date for the recommendation to come into force based on the needs of the vaccine campaign, the ministry said.
