If the AZ vaccine is causing these rare blood clots (CSVT) that the German authorities are concerned about, you would expect dozens of cases in the UK data. But there are three.
Health professionals, is it possible other countries have just been better at diagnosing CSVT?
And a related question. If a link between the AZ vaccine and CSVT is shown, how bad would it need to be for approval to be rescinded?
A link between the contraceptive pill and CSVT looks well-established.
The major difference between the UK and the EU is politics and public trust. The UK has much more underlying trust in vaccines and there isn't a political party which is persuing any kind of anti-vax line. Unfortunately this is not true in the EU. There is a much higher prevalence of anti-vax sentiment.
In some respects being over cautious in order to dispell any fears is prudent. The problem is the way that this has been reported throughout the UK and EU is totally counter productive to this, and quite frankly nothing short of irresponsible. Media has gone for the sensationalist line rather than accurate and considered reporting which WILL scare people.
DH has already seen people he knos saying they won't get their second dose now and even he - who is very pro-vaccine - has admitted to feeling anxious about getting vaccinated now. (He will He's not daft. His comment was more if thats how he was feeling plenty of others will be swayed not to have it at all).
The question above about 'how many cases, is too many cases?' is the real one to follow. Not whether the vaccine causes more blood clots (and there is evidence which may suggest that in fact the converse maybe true anyway.
It is worth remembering that WHO say AZ is safe and it should be continued to be used and the European Medicine Agency are saying it is safe and it should be continued to be used. It is NOT just the UK agencies and government.
The action is coming from individual governments (ie political) rather than regulators and health advisory bodies (ie science led). And anyone with any kind of doubt creeping in should keep an eye on this dynamic over and above what is said on the news and in the media - who is saying and doing what and why.
I am fully expecting the PM to very publically have his vaccine in the next fortnight or so, and if he does, I will be amazed if it is anything but AZ.
