Pharmaceutical companies delivered Covid vaccines at unprecedented speed. Nearly five years on, a sweeping international study tracking almost 100 million people is pushing the global conversation into uncomfortable territory. Elevated blood pressure. Myocarditis. Unusual menstrual changes. And those are only the first signals. What researchers uncovered has unsettled physicians and left many patients searching for answers… Continues…
