A semi-lengthy update on the Astra Zeneca vaccine.
If you don't read this through, take this message home: despite the clot risk, for the vast majority of people the vaccine is SAFE and EFFECTIVE and should not be avoided.
Now for the details:
The link between Astra Zeneca vaccine and clots has been established as causal. This means the science points to evidence that the vaccine IS causing the clots. The rate this is/has happened is at 1 in 100 000. https://www.nejm.org/doi/full/10.1056/NEJMoa2104840?query=featured_home
What does this mean for you and receiving the vaccine?
The baseline risk for ANY clot is 1 in 1000. With the AZ vaccine it is 1 in 100 000
The AZ risk is not related to previous clot, medications or medical conditions.
The benefits of the AZ vaccine need to be weighed against this risk, which I'm about to show you.
Three graphs posted in the comments below showing the clot risk (right side) vs. ICU admissions prevented every 16 weeks by the vaccine (left side). The risk of the left side is based on your region: low risk for COVID up to high risk for COVID.
What region are you in and what's your risk? See the fourth and fifth pictures. Look at the column case rates per 100 000. Low risk for the first group of graphs is defined as 20 per 100 000. Moderate risk at 60 per 100 000 and high risk at 200 per 100 000.
Grey Bruce is between low and moderate risk at this time which means for people over 30, the benefits of the AZ vaccine FAR outweigh the risks. For low risk people under 30, the balance might shift away from AZ.
In a high risk region, for all patients the benefits outweigh the risks.
