Secondo uno studio rilevato dall’Università di Oxford, in collaborazione con l’Office for National Statistics, una dose di vaccino AstraZeneca o Pfizer riduce il rischio di contagio da coronavirus di quasi due terzi. Analizzando i risultati dei test del Covid di oltre 350.000 persone nel Regno Unito tra dicembre e aprile.
Non si intravede la luce in fondo al tunnel: il covid sembra non volersi arrestare. In base all’ultimo studio condotto dall’Università di Oxford, infatti, si tenterà di contagiare nuovamente un gruppo giovani che hanno già avuto il Covid-19. Esponendoli al virus per la seconda volta, gli scienziati cercheranno di capire come reagisce il sistema immunitario.
Astrazeneca’s vaccine trials in children have been suspended pending analysis by Oxford University, which is testing possible links between the drug and thrombosis in adults.
Professor Andrew Pollard explained that researchers at Oxford University had decided to suspend the trials pending further information. The trials started in February and involved children between 6 and 17 years old. About 300 volunteers had come forward.
“Although there are no safety concerns in the paediatric trial, we are awaiting further information from Mhra (the UK Medicines Authority, ed) on the rare cases of thrombosis and thrombocytopenia that have been reported in adults, before administering any further vaccines“, Professor Pollard explained.
The preliminary timetable for the European Medicines Agency’s press conference on the new Pharmacovigilance Risk Committee (Prac) assessment of AstraZeneca’s vaccine in relation to rare events of cerebral thrombosis is set for 4pm today, the Ema said in a statement.
