IS Daniela Schirru, 52-year-old architect from Prato, the first woman in Italy to have completed the vaccination scheme against Covid with a different serum from that used for the first dose. His “heterologous vaccination” began with AstraZeneca and completed with Pfitzer, at the Aulla clinic in Lunigiana, province of Massa-Carrara in Tuscany.
“We needed a first guinea pig,” he explained to The nation immediately after inoculation. “I feel good. And now I’m going home. I thank the team of professionals of the Aulla clinic for their professionalism, competence and attention.
Qualities that I had already detected for the first vaccination ».
Daniela Schirru was not afraid. “No,” he confirms. “I felt like a guinea pig. But it was necessary“. After the vaccination, she was kept under observation for longer than the ordinary protocol, and “now every two weeks, for three months, she will be subjected to specific checks. His vaccination with two different drugs has a scientific value ”, explained doctor Lucio Barani. “You have been asked to be available for any future studies by the medical team.”
On the heterologous vaccination, adopted after the AstraZeneca vaccine was stopped for the under-60s (who will carry out the booster with a different serum, with mRNA), the Minister of Health, Roberto Speranza, is positive: “Heterologous vaccination is already used by major countries such as Germany for several weeks, but also in other areas of the world, and the results are encouraging, ”he explained in a meeting with journalists. “There are some studies that testify that the immune response is even better than that with two doses of the same vaccine.” Sergio Abrignani, immunologist of the University of Milan and member of the Technical Scientific Committee (Cts), is of the same opinion, according to which heterologous vaccination “it is not an experiment. We know they are extremely safe vaccines. For all the works published abroad with the combination of the two vaccines, we know that they are safe and indeed improve the immune response ».
