Based on a recommendation from the Paul Ehrlich Institute (PEI) on March 15, 2021, the German Federal Government suspended COVID-19 vaccinations with AstraZeneca as a precautionary measure. Further investigations were necessary. The European Medicines Agency (EMA) examined whether and how the new findings would affect the vaccine's approval. Following intensive consultations regarding the serious thrombotic events that had occurred in Germany and Europe, the Paul Ehrlich Institute (PEI) recommended the temporary suspension of vaccinations with the AstraZeneca COVID-19 vaccine. As of Monday, March 15, 2021, further cases had been reported in Germany since March 11, 2021. Analyzing the new data, experts at the Paul Ehrlich Institute observed a striking cluster of a specific form of very rare cerebral venous thrombosis (sinus vein thrombosis) in conjunction with a deficiency of blood platelets (thrombocytopenia) and bleeding in close temporal proximity to vaccinations with the AstraZeneca COVID-19 vaccine. The data were further analyzed and evaluated by the European Medicines Agency (EMA). Until the EMA's assessment is complete, vaccinations with the AstraZeneca COVID-19 vaccine have been suspended in Germany. This decision applies to both primary and booster vaccinations. The Paul Ehrlich Institute advised that individuals who have received the AstraZeneca COVID-19 vaccine and experience increasing discomfort more than four days after vaccination, for example, with severe and persistent headaches or pinpoint skin hemorrhages, should seek immediate medical attention.

Prof. Dr. Hartmut Göbel: “The onset of headaches, usually lasting four days or more, in conjunction with neurological symptoms such as dizziness, visual disturbances, tinnitus, and eye muscle paralysis, as well as varying degrees of altered consciousness, is the key symptom constellation for cerebral venous thrombosis. These headaches differ significantly from typical headaches following a COVID-19 vaccination. The latter occur in approximately 50% of cases within 17 hours of vaccination and last an average of 18 hours. Altered consciousness is not a common accompanying symptom.”

The European Medicines Agency (EMA) reviewed the situation and recommended on March 18, 2021, that vaccinations with the AstraZeneca vaccine continue. The federal and state health ministers decided on March 18, 2021, to resume vaccinations with the AstraZeneca vaccine starting March 19, 2021. This decision was based on the fact that the benefits of the vaccine in combating the still widespread threat of COVID-19 continue to outweigh the risk of side effects. A warning was added to the product information.

A Dear Healthcare Professional Letter dated March 24, 2021, explains: “Vaccinated individuals should be advised to seek immediate medical attention if they develop symptoms such as shortness of breath, chest pain, leg swelling, or persistent abdominal pain after vaccination. Furthermore, anyone experiencing neurological symptoms after vaccination, such as severe or persistent headaches or blurred vision, or who develops bruising (petechiae) on the skin outside the injection site a few days later, should seek immediate medical attention.”

In this context, the question arises as to why, in Germany, vaccination with the AstraZeneca vaccine was restricted to people under 65, contrary to its approval by the EMA (European Medicines Agency), citing insufficient efficacy data in older people. that young women in the healthcare system , such as nurses and doctors, have been given priority for treatment with this vaccine. The benefit of an additional warning about complications in the package insert, when no alternatives are offered, remains unclear. This would be understandable if no other options existed. However, such options were available, including vaccines from BioNTech/Pfizer. According to current findings, young women belong to the high-risk group for the described complications. Consequently, on March 29, 2021, the Euskirchen district decided with immediate effect to no longer vaccinate women under 55 with the AstraZeneca vaccine. Following the death of a 49-year-old nurse, Rostock University Hospital announced on March 26, 2021, that it is suspending AstraZeneca vaccinations for people with high blood pressure, obesity, and women taking birth control pills. Similarly, the Canadian expert panel for the COVID-19 vaccination campaign currently recommends suspending the AstraZeneca vaccine for people under 55. According to a report from March 30, 2021, the state-owned Charité and Vivantes hospitals in Berlin are also suspending AstraZeneca vaccinations for women under 55. Following Berlin's announcement, the city of Munich also announced on August 30, 2021, that it will no longer administer AstraZeneca to anyone under 60 until further notice. On March 30, 2021, the directors of five university hospitals in North Rhine-Westphalia also advocated for a temporary halt to vaccinations of younger women with the AstraZeneca vaccine. And also on March 30, 2021, the Standing Committee on Vaccination (STIKO) announced: “Based on the currently available, albeit still limited, evidence and taking into account the current pandemic situation, STIKO recommends using the AstraZeneca COVID-19 vaccine for people over 60 years of age. Its use below this age remains possible at the discretion of a physician and with individual risk acceptance after careful consultation. STIKO will issue a statement regarding the second vaccine dose for younger people who have already received a first dose of the AstraZeneca COVID-19 vaccine by the end of April.”
