If you develop a clot following the vaccine, wouldn't that mean there's a high chance you would have been one of the unlucky ones anyway with COVID?

I know it's tricky to test, but given that the vaccine causes your body to produce the COVID spike protein, and COVID itself is known to cause similar clotting, doesn't this mean that the people who developed clots following the vaccine would have been much more likely to develop clots as a result of COVID anyway?

I think that’s a credible theory but I’m in no way qualified to pick it apart.

I have wondered this too

I don't think so.

I haven't heard of any clotting cases associated with covid that are caused by an autoimmune response that produces antibodies to platelet factor 4, I think the vaccine clots are produced by a very different mechanism to the clots associated with covid.

Also it seems to only occur with the adenovirus vector vaccines - AZ and J&J. Which suggests it's related to either the adenovirus or the combination of the adenovirus and spike protein. If it was just a response to the spike protein then I'd expect to see it with the mRNA vaccines too.

I don't think anyone knows why you develop the clots yet. Someone may come along and say different though

@Utini interesting!

There has been some noise about blood clots caused by Pfizer, but I'm struggling to find any information from a reputable source (seems to be mainly anti-vax websites and the Fail).

@JesusInTheCabbageVan yes I'd seen similar, but I've not seen anything reputable that shows clots occuring with Pfizer at anything more than the normal background rate.

I also don't think they're seeing any of these unusual cases with simultaneous clotting and low platelets, that appear to be autoimmune and are occurring with AZ.

I guess they're keeping a close eye on it and investigating any possible links with other vaccines, hence the speculation in the Mail!

Actually my GP advised me about the Pfizer clots so I’d take that as a credible source. I have APS so it was in conjunction with discussions about a suitable vaccine (before AZ was taken off the table for APS/under 40s)

But the main issue isn't about clots, it's about having the choice to chose a vaccine that doesn't cause these clots.

Regardless, I’d probably risk any vaccine vs covid risk.

I agree that we should have the right to choose what treatment we receive.

Absolutely, but if we all delay until we have a completely bomb-proof vaccine, we'll be waiting years and far more of us will die of COVID in that time than would have died from the vaccine.

Note that this article is from June 2020. Now whether this can be related to vaccine clotting is a different issue, but it would be wrong to overlook the risk of clots from the disease.

I doubt it.

It’s the same line of thinking as “if I had no side effects from the jab, does that mean I’d have handled covid pretty well!” when there’s no correlation.
