The European Medicines Agency has reported that it's aware of 25 cases of rare blood clots from people who have had the Pfizer mRNA vaccine, and 5 cases from people who have had the Moderna vaccine.
The numbers were revealed during a press briefing into blood clotting issues related to the Johnson and Johnson vaccine.
It's the first time such a number has been reported by a medical regulator, and may suggest very rare clotting events may not be confined only to AstraZeneca and Johnson and Johnson.
The co-chair of Australia's vaccination advisory group Professor Allen Cheng has told Coronacast that there is still a lot of uncertainty, especially if reported cases have been fully investigated.
So on today's Coronacast, what has the EMA said and is it real?
