John Skerritt, Therapeutic Goods Administration: Of the total 60 (adverse cases) reported in last cut off date, we actually hadn't had all that many in their 50s and suddenly we were seeing this worrying trend.

We do a weekly assessment of cases of any adverse events and what was remarkable in the cases received between June 11 and June 17 ... we had seven out of 12 new cases occurring in their fifties.

More nonsense. There's nothing sudden about the news that AZ causes blood clots - in any age group. That info has been there since AZ was first rolled out in Europe many months ago whereupon most countries suspended/banned it.

Yes, the TGA 'suddenly decided to see' the data, and belatedly cover their arses by upping the age limit, but it's silly to argue that blood clots are a 'remarkable' new phenomenon.

The thing is, now Australia is in a situation where around 300 000 people in their 50's have had the first shot of AZ - what should they do now?

There's talk of 'mix n match' with Pfizer, but that's more untested craziness.

The TGA is still encouraging 50-60's to get their second AZ dose due to their "risk- benefit equation". How many of the above are going to be on the wrong side of that equation?

As mentioned, it's hard to find trustworthy figures on vaccine deaths, but Korea is reporting about 1 in 7000 amongst those over 75.
