Study of Covid vaccinations supports their safety

A global study on Covid vaccines has identified small increases in heart, blood, and neurological disorders among recipients. Pfizer, Moderna, and AstraZeneca shots were linked to higher risks of certain conditions, including nerve-wasting and brain-swelling disorders. Despite this, the absolute risk remains low, with only 2,000 cases among 13 billion doses administered. Notable findings include a threefold increase in myocarditis and a higher risk of Guillain-Barre syndrome. Concerns over neurological events following vaccination were outweighed by the significantly higher risk associated with SARS-CoV-2 infection. Additionally, AstraZeneca shots were associated with an increased risk of two types of thrombosis. While the study shows potential risks, it underlines the benefits of vaccinations in preventing Covid-related deaths.
