B.C., Canada, and many regions around the world have robust systems to monitor vaccine side effects, commonly referred to as adverse events following immunization. This includes the COVID-19 vaccines currently being offered.
While the side effects we are seeing in B.C. and Canada largely correspond to those identified in the vaccine trials, rare cases of serious blood clots have been reported in individuals after they received the AstraZeneca or COVISHIELD vaccine.
However, the risk of serious blood clots with the second dose is about 1 in 600,000. This is a rare event and the risk is lower with the second dose than with the first dose, which is about 1 in 50,000.
People in B.C. who received the AstraZeneca or COVISHILED vaccine will have the option to get a second dose of one of these vaccines or to get an mRNA vaccine for a second dose.

Talk with your primary care provider, pharmacist, or call 8-1-1 (HealthLink BC) if you have any questions prior to booking an appointment for your second dose.
