BARRIE, ONT. -- As more age groups in Ontario are eligible to receive AstraZeneca’s COVID-19 vaccine, an Ontario doctor is reminding the public severe reactions to the dose are rare and some side effects are common.

Earlier this week, the provincial government lowered the age eligibility to receive the AstraZeneca in an effort to get more people vaccinated against COVID-19 with at least one dose, noting that severe symptoms are “‘incredibly rare,” such as blood clots.

"You're 250 times more likely to get a blood clot from flying across the ocean than you are to get it from the AstraZeneca vaccine," said Dr. Sohail Gandhi, the former Ontario Medical Association's president.

Although unlikely, Dr. Gandhi said if you feel unwell four days after the shot, there are a few symptoms to look for, such as severe headaches, neurologic symptoms like having trouble speaking or seeing, and having difficulty using your arms and legs.

He noted if you experience these symptoms seek medical attention.

Dr. Gandhi mentioned five to 10 per cent of people could experience symptoms after receiving any vaccine within the first two days.

Select pharmacies and primary care providers across Simcoe County and Muskoka are currently offering the AstraZeneca vaccine to residents 40 and older.
