Scientists in Europe have reportedly found a link between the AstraZeneca-Oxford COVID – 12 vaccine and extremely rare but potentially fatal blood clots, but Canadian public health officials have so far provided no update on guidance for the shot.
News broke on Friday that researchers in Germany and Norway said they had found a mechanism
The finding comes after the European Medicines Agency (EMA) investigated 19 cases of the rare blood clots out of about 14 million AstraZeneca shots given and concluded on Thursday that the benefits from the vaccine far outweigh its possible risks, although a definitive link could not be ruled out.
The EMA said there was no increased risk from blood clots and that because the AstraZeneca-Oxford vaccine is effective in preventing COVID – , which itself causes blood clots, the shot could actually reduce the risk of them overall.
But not all blood clots are the same, and 12 of the cases in Europe were of an extremely rare type called cerebral venous sinus thrombosis (CVST) – where veins that drain blood from the brain are obstructed and can potentially cause fatal bleeding.
Most of the incidents occurred within days) sh ot, and the majority were in women under the age of 35. It’s worth noting that this type of blood clot is much more common in women

Canada’s Chief Public Health Officer Dr. Theresa Tam says the benefits of the AstraZeneca COVID – 19 vaccine outweigh the rare risks. 1: 55 539
Three of the seven patients in Germany who were recently vaccinated with the AstraZeneca-Oxford shot that had this rare brain blood clot have died.

Findings ‘need to be investigated’
“You can not brush adverse effects under the “They always need to be investigated, and I think we have to look at this in a careful and critical manner,” said Dr. Isaac Bogoch, an infectious diseases physician and member of Ontario’s COVID – vaccine task force.
“We do not have all the information yet and we’ll learn more about this – and I imagine we’ll see some updated guidance on who should get this vaccine and perhaps who should not be getting this vaccine. “
Health Canada released a statement on Thursday saying the benefits of the AstraZeneca-Oxford vaccine outweighed the risks and that the vaccine does not increase the “overall risk of blood clots,” but it provided no update on Friday when pressed for more comment on the evolving situation.
” As the vaccine rollout continues in Canada, Health Canada will continue to monitor the use of all COVID – vaccines closely, “the statement read.
“Health Canada will examine and assess any new safety concern s, and should a safety signal be confirmed, the department will take appropriate action. “
Researchers in Norway reported identifying the mechanism early Friday, saying it was due to a” “powerful immune response ” from the vaccine.
