Largest Covid vaccine study ever finds shots are linked to small increased risk of neurological, blood and heart disorders - but they are still extremely rare
Daily MailCovid vaccines have been linked to small increases in heart, blood, and neurological disorders, according to the largest global study of its kind. There was also a 1.3 to 1.4 times greater risk of having a seizure following the first and second doses of the Moderna vaccine, as well as the fourth dose of the Pfizer vaccine. Researchers in Israel spotted 2.7 extra cases of myocarditis per 100,000 people who were injected with the Pfizer vaccine, but this shot up to 11 additional cases for every 100,000 individuals who caught the virus The graph shows the number of extra cases of each adverse effect per 100,000 people after a Pfizer injection and a Covid infection Landmark study finds sudden cardiac deaths in sport fell over time UK cardiologists say the findings from the 'landmark' Swiss and US study should reassure people about the safety of the mRNA Covid vaccines and the risk of myocarditis. The researchers added a major caveat to this finding: ‘Chances of having a neurological event following acute SARS-CoV-2 infection were up to 617-fold higher than following COVID vaccination, suggesting that the benefits of vaccination substantially outweigh the risks.’ After a first dose of the AstraZeneca vaccine, there was a 3.2-times-greater than expected risk of Cerebral Venous Sinus Thrombosis. Also after the first dose of the AstraZeneca vaccine, there was a 1.07 times higher risk of thrombocytopenia, a condition characterized by a lower-than-normal number of platelets in the blood.
