In addition to the severity of the clots, the difference is that the side-effect is not expected and not mentioned in the patient information. Quote from the German PEI institute [1]: > It is true that for birth control pills thromboses, even with fatal outcome, are known as a very rare side effect. They are listed in the Summary of Product Characteristics (SmPC). The birth control pill is available only on prescription. Every woman must be informed of this risk by the prescribing physician. For the COVID-19 Vaccine AstraZeneca, there is currently a suspected very rare side effect of sinus vein thrombosis with accompanying platelet deficiency, sometimes fatal. It is not listed in the SmPC. The whole statement is quite informative: [1] https://www.pei.de/EN/service/faq/coronavirus/faq-coronavirus-node.html;jsessionid=B3DBF50FFC88430B52DF246820E23E88.intranet241?cms_tabcounter=3 https://www.pei.de/EN/service/faq/coronavirus/faq-coronaviru...
