“When Barbara Holland, professor of mathematics at
the University of Tasmania, was making the decision to have an AZ jab now
rather than wait for Pfizer, she deployed her number-crunching prowess.
Using UK data, she calculated that “I’d have about
a 1/60,000 chance of dying of Covid-19 in the next 90 days; balance that
against a 1/900,000 chance of a fatal blood clot, working off a 1/30,000 chance
of a clot x 1/30 chance of it being fatal.”
