Here's something that's a bit annoying. If you try to do a bit of self help and read up on Coeliac related subjects, most of the web search engines point to the Coeliac UK web site. Fair enough; it's the one the NHS point you too as they show you the door after a gastroenterologist has confirmed you're coeliac. At first sights, CUK appear to have lots of high quality information, but when you try delving into it you either get directed around in circles through 'Your Questions Answered' lists or you finally find an article by an expert that tells you its a complicated subject and nobody really knows the answer because not enough research or studies have been carried out. The really annoying part though, is that nobody seems to think its important to put a date on anything any more.
The knowledge on how Covid -19 and Coeliac disease are related, and advice to Coeliacs regarding vaccination and self-protection , appears to be differ depending on what you read, but an article or a statement could be a year old or bang up to date. No way of telling unless the article has a date on it.
