Persistent questions on whether rare but serious blood clots among those getting the AstraZeneca jab against Covid-19 are more frequent than in the general population have undermined confidence in the beleaguered vaccine.

"In my opinion we can now say it, it is clear that there is an association with the vaccine".

A senior official in the agency said in an interview published on Tuesday that there seemed to be a connection, although it was unclear how this happened.

Scientists are exploring several possibilities that might explain the extremely rare brain blood clots that occurred in individuals in the days and weeks after receiving the AstraZeneca vaccine.

Mr Cavaleri said they are still trying to understand where exactly this link comes from.

But it has said that a causal link between clots and the vaccine is possible, and is expected to provide an updated assessment this week.

Ireland was one of those countries that suspended the rollout of the vaccine. Still, countries are counting on the shot to help them exit the pandemic, and millions of doses have been administered across the region.

"Among the vaccinated, there are more cases of cerebral thrombosis. among young people than we would expect".

Investigations are underway to determine if the rare syndrome is a side effect from the AstraZeneca vaccine or just a coincidence.

"The U.K. needs to be on high alert as it starts using the vaccine in younger people", Sam Fazeli, an analyst with Bloomberg Intelligence, wrote in a report.

"We were scheduled to have received over 3 million doses of the AstraZeneca vaccine from overseas by now, which have not arrived in Australia because of the problems with shipments that we've seen happening here and in other parts of the world", Acting Chief Medical Officer Michael Kidd told Sky News.

Twomey also blamed the slow rollout on a lack of co-ordination between the Australian national government and states, with the latter complaining about slower-than-expected distribution and a lack of certainty on vaccine supplies.

In Germany, there have been 31 suspected cases of CVST - 19 accompanied by a drop in blood platelets - with nine deaths, according to the Paul-Ehrlich Institute.
