Adverse Events

ADVERSE EVENTS

Adverse events are extremely rare and include anaphylaxis (severe allergic reaction) and fainting. 

A vast majority of adverse events occur within 30 minutes after vaccination. For this reason, you will need to remain in our clinic for observation for up to 30 minutes after each dose of the vaccine, in case of an adverse event, and to receive rapid medical care if needed. If you experience severe symptoms such as difficulty breathing, wheezing, a fast heartbeat, or collapsing, after you have left our clinic, call 000.

Furthermore, there is a link between the AstraZeneca vaccine and an extremely rare blood clotting syndrome (thrombosis with thrombocytopenia). If you develop a severe or persistent headache, blurred vision, shortness of breath, chest pain, leg swelling, persistent abdominal pain unusual skin bruising and/or pinpoint round spots beyond the site of injection, in 4 to 20 days after vaccination, seek immediate medical attention. Be sure to tell your treating doctor that you have recently received the vaccine. If a clotting disorder is confirmed, urgent hospital care is required.
