Covid, Burioni: “Excellent, good and bad news”

“Great, good and bad news”. Professor Roberto Burioni, with a series of tweets, provides information on some studies related to vaccines and covid. “Great news. The vaccines (Pfizer and AstraZeneca) retain a remarkable efficacy against symptomatic delta variant infection ”, writes the virologist referring to what is published in the New England Journal of Medicine. Other “excellent news”, from the same publication, comes on the third dose of the vaccine: “A third dose effective in inducing a robust potentially protective immune response in transplant recipients”. The “good news” refers to the study that the Moderna vaccine is “effective and safe in adolescents (12-17 years)”. The “bad news” is linked to a study conducted in Sweden. “Covid-19, even when it passes without apparent consequences, predisposes to a heart attack. Get vaccinated “.
