My sister lives in Italy. She had her first dose of AZ and has now been told she has to sign a contest form if she wishes to go ahead with her second dose of AZ.
The consent form lists the risks of the second dose and asks her to sign that she agrees that she is going against the government’s advice (Gov advise to have Pfizer as the second dose)
Her preference was to stay with the same dose and now she’s really put off with having to sign a consent form so hasn’t had a second dose at all..!!
I don’t understand why she has to consent to accept the risks of a second AZ but not to have a different vaccine altogether. 
She did say a lot of people her age feel the same way, so surely a lot of young Italians will not be fully vaccinated if faced with this.
