Australia's expert advisory group on vaccines has recommended the COVID-19 vaccine be deferred for people who have a history of specific rare blood clotting disorders.

The Australian Technical Advisory Group on Immunisation says for the time being it recommends that vaccination with any COVID-19 vaccine should be deferred for people who have a history of two very rare and specific conditions.

This is the first time a warning has been given for COVID-19 vaccines in Australia, and the recommendation applies to both Pfizer and AstraZeneca vaccines, although the current concerns have been focussed on the latter.

So on today's Coronacast, why has the expert panel decided to make this move now? And for the very small number of people affected, what should they keep an eye out for if receiving a vaccine?
