Chief public health officer Dr. Theresa Tam commented Friday on the news that Health Canada had found the benefits of AstraZeneca’s COVID-19 vaccine “continue to outweigh the risks” after investigating reports of blood clots in several countries. She said rare adverse reactions are expected when vaccines are deployed on a global scale and they “must be taken seriously and investigated thoroughly.”
