The vaccination skepticism of the Germans and the concern about serious side effects after a corona vaccination is still great. But new studies are now giving the all-clear. Corona vaccinations therefore do not increase the risk of stroke. On the contrary, they should even protect infected people from it.
A few days ago, the European Medicines Agency approved the new vaccines from Biontech/Pfizer and Moderna that have been adapted to Omikron. According to Health Minister Karl Lauterbach, the vaccines will be available from next week. A recommendation from the Standing Vaccination Commission (Stiko) is still pending. She only recommends the second booster with the vaccines available to date to people over the age of 60 and people over the age of 5 who belong to a risk group.
As with any vaccination, the benefits and risks of corona vaccinations must be carefully weighed. Every vaccination has side effects. Even if experts emphasize that the corona vaccines are safe and side effects are minimal and serious health consequences from vaccination are rare.
However, the occurrence of some sinus vein thrombosis in the brain after vaccination with both Astrazeneca vector vaccines and also Johnson
A new study, which was only published in the journal Neurology at the end of August, now gives the all-clear. A research team led by the physician Maria-Ioanna Stefanou from the Kapodistrian University of Athens evaluated the data from 16 different studies. It recorded over 17,481 strokes from a total of over 780 million vaccinations. From this, Stefanou and her team calculated a rate of 4.7 strokes per 100,000 vaccinations.
The researchers conclude that the risk of stroke after vaccination is no higher than the general risk of stroke in the population. This applies to both vector and mRNA vaccines. The researchers were also able to find something else: The risk of stroke in vaccinated people is much lower than in Sars-CoV-2 infected people who are not vaccinated. Results that speak clearly for a vaccination.
Another study from France also seems to confirm this. It was also only published at the end of August by the French agency for the safety of medicines and healthcare products, ANSM, in the ” Annals of External Medicine “. It is based on the analysis of data from the French National Health Data System.
The study examined how often cardiovascular events such as heart attacks, pulmonary embolisms and strokes occurred in people between the ages of 18 and 75. In this regard, the evaluation was able to find over 70,000 events in 37 million vaccinated people. Overall, the study showed that there was no association between mRNA vaccines and the occurrence of major cardiovascular complications. For Astrazeneca and Johnson vector vaccines only

“At least for the mRNA vaccines, the data available do not show any safety signals in relation to an increased risk of stroke,” said Secretary General of the German Neurological Society Peter Berlit, assessing the results from France in a press release. The opposite is even the case. According to this, unvaccinated Sars-CoV-2 infected people have a higher risk of stroke – so the vaccination protects against it.
According to Berlit, this is also the result of a new Korean study that examined the data of over 230,000 infected people. Of these, over 60,000 were unvaccinated and over 168,000 fully vaccinated. Although the vaccinated were older and had more underlying diseases, severe Covid 19 courses were less common in this group. The risk of vaccinated people suffering a stroke was half that of the unvaccinated group.
