Cressida Ross Reposting your question here as it was mistakenly submitted under the "Announcements" group:

I have 2 students in Italy from 24/1/22 to 4/3/22. One is double vaccinated the other boosted. Both of their last vaccinations were last summer so according to the rules of 6 months after vaccination the Super Green Pass will expire at the end of February. Currently there is no offer of a 4th vaccine and the Student from the US cannot be boosted in the US before she leaves. What happens with these situations?
