Clots and vaccines
March 15, 2021 by ferniglab
Blood clots, for instance, deep vein thromboses or pulmonary embolisms, are critical and we must always rightly be involved about these. With ~ 17 M doses of the AZ vaccine delivered into individuals, we’ve studies of 15 instances of deep vein thrombosis and 22 instances of pulmonary embolism. Deep vein thrombosis happens at charge of 0.1% (so 1 in 1000) throughout all age teams, growing with age. So each day meaning round 47 instances in a inhabitants of 17 million – the truth is it will likely be extra, as a result of these vaccinated will not be consultant of the inhabitants, however an older phase.
If we contemplate that vaccination has been taking place at a excessive charge for slightly over 2 months, then we count on at the very least 2,800 instances of deep vein thrombosis.
We are able to draw some restricted conclusions concerning clots, the AZ and different vaccines.
- The reporting mechanism could also be very, very poor, and solely a fraction of affected person outcomes are reported. That is in stark distinction to a scientific trial, the place ALL outcomes re reported – recall that one poor particular person on the Pfizer/BioNT trial was killed by a lightening strike, and within the AZ trial there have been 2 deaths within the vaccination group and 4 within the placebo group. These and different deaths have been unrelated to the vaccine.
Selective reporting results in fantasy.
- Reporting just isn’t so poor, so the correlation is that vaccination protects towards thrombosis. With out understanding the standard of reporting of hostile results and the probability {that a} good many clinicians will contemplate many situations in vaccinated sufferers to be unrelated to the vaccine, this intriguing chance stays a chance and no extra.
- “Clot”, at the very least for UK audio system of English has a second that means, akin to the US ‘blockhead’. It might be that the AZ vaccine prompts clots in authorities.
At current the more than likely causal relation is (3). It’s because we’ve ample proof unbiased of vaccination programmes that show an typically increased focus of clots in authorities and within the higher reaches of many greasy poles than one would count on have been altitude to correlate in a roundabout way with skill.
Observe: H/T @archer_rs who jogged my memory that the one vaccine that’s non-profit is the AZ vaccine. The historical past of medication teaches us that the revenue motive results in hiding actual and critical hostile occasions.
