Have you had your first dose of the AstraZeneca vaccine?
If you have already had one dose of AstraZeneca and you did not experience severe side effects, you should receive a second dose of AstraZeneca. The rare blood clotting condition, TTS, is rarer still in second doses of the AstraZeneca vaccine.
It is still important that every person who receives a COVID-19 vaccine receive the full two-dose course of the same vaccine to provide the best immune response. Be assured at http://www.health.gov.au/COVID-19-vaccines
