The investigation into potential side effects related to the AstraZeneca-Oxford COVID-19 vaccine continued to reverberate across the globe, with several more European countries suspending its use, and others such as Australia saying they have no plans to stop immunization.The European Medicines Agency (EMA) and an expert group at the World Health Organization (WHO) are reviewing data and weighing the evidence this week on thromboembolic events in people who were vaccinated, and their conclusions are expected later this week.
