Astra Zeneca - 3rd dose or booster - risk of blood clots - any studies?

[marigoldflower]

Hello All,

My DH will probably be advised to have the AZ booster rather than Pfizer of Moderna. He had the first two AZ doses with minimal symptoms so he is ok with this.

Does anyone know if there have been any studies or can link to articles to whether the risk of blood clots is still present with a third AZ vaccine? i.e. if you have had no blood clots with the first two doses, then it's more likely that you will have no serious side effects with the third?

I remember reading that some had blood clots 14 days after the second dose (so presumably you are running the same risk every time you get a shot, or is the risk somehow lessened?)

I was wondering as the whole topic sort of 'resurfaced' this week as scientists apparently found what triggers this side effect (which I know is rare) and I was wondering.

I wish things didn't move so fast and there was more time to take everything in!

@soredust I have a documented medical history that meant I could only have Az originally, that hasn’t changed and is why I had it as a booster

As stated by others it’s only given for very specific reasons, DH had Pfizer as his booster and both teen DC had Pfizer as their first two vaccines and will have what is offered for their booster (both category 6) because they don’t have such a severe allergy history

The mix of both really is the best option if you can have it, I only posted so that people in my situation will know that they can still have AZ if it is deemed medically necessary

I had to have AZ as booster because I am allergic to Potassium Chloride which is in both Pfizer and Moderna. It did mean I had a bit of a schlep to find a vaccine centre who had AZ as a booster (5 hour round trip). No side effects so far (3 weeks later).
