  Several European countries have suspended the inoculation of the AstraZeneca
vaccine out of suspicion of causing deep vein thrombosis. In this letter we
report some Fermi estimates performed using a stochastic model aimed at making
a risk-benefit analysis of the interruption of the delivery of the AstraZeneca
vaccine in France and Italy. Our results clearly show that excess deaths due to
the interruption of the vaccination campaign injections largely overrun those
due to thrombosis even in worst case scenarios of frequency and gravity of the
vaccine side effects.
