Safety of the AstraZeneca Vaccination

For the vast majority of our population the benefits of the AstraZeneca Covid-19 vaccine outweigh any risks and you should still book your COVID-19 vaccine when asked to do so.  

Recently, there have been reports of a very rare condition involving blood clots and unusual bleeding after vaccination. Although this condition remains extremely rare there appears to be a higher risk in people shortly after the first dose of the AstraZeneca (AZ) vaccine. Around 4 people develop this condition for every million doses of AZ vaccine doses given. This is seen slightly more often in younger people and tends to occur between 4 days and 2 weeks following vaccination. This is being carefully reviewed but the risk factors for this condition are not yet clear. 

This condition can also occur naturally, and clotting problems are a common complication of COVID-19 infection. An increased risk has not yet been seen after other COVID-19 vaccines but is being carefully monitored.  

If you have already had your first dose of AZ vaccine without suffering a blood clot as a side effect you should have your second.  

For the vast majority of our population the benefits of the AstraZeneca Covid-19 vaccine outweigh any risks and you should still book your COVID-19 vaccine when asked to do so.
