Clots and vaccines | Ferniglab Weblog

Blood clots, for instance, deep vein thromboses or pulmonary embolisms, are critical and we should always rightly be involved about these. With ~ 17 M doses of the AZ vaccine delivered into individuals, we have now experiences of 15 circumstances of deep vein thrombosis and 22 circumstances of pulmonary embolism. Deep vein thrombosis happens at charge of 0.1% (so 1 in 1000) throughout all age teams, rising with age. So day by day which means round 47 circumstances in a inhabitants of 17 million – in truth will probably be extra, as a result of these vaccinated are usually not consultant of the inhabitants, however an older section.

If we take into account that vaccination has been taking place at a excessive charge for just a little over 2 months, then we anticipate a minimum of 2,800 circumstances of deep vein thrombosis.

We are able to draw some restricted conclusions concerning clots, the AZ and different vaccines.

1. 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.

2. Reporting just isn’t so poor, so the correlation is that vaccination protects towards thrombosis. With out understanding the standard of reporting of opposed results and the probability {that a} good many clinicians will take into account many situations in vaccinated sufferers to be unrelated to the vaccine, this intriguing chance stays a chance and no extra.
3. “Clot”, a minimum of for UK audio system of English has a second which means, akin to the US ‘blockhead’. It could be that the AZ vaccine prompts clots in authorities.

At current the more than likely causal relation is (3). It’s because we have now ample proof unbiased of vaccination programmes that show an usually larger focus of clots in authorities and within the higher reaches of many greasy poles than one would anticipate have been altitude to correlate indirectly with capacity.

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 opposed occasions.
