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.
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.
The ministry added that the decision reflects the still high circulation of the virus and the effectiveness that booster shots had shown in preventing Covid-related deaths and, more generally, symptoms that would require hospitalisation.
