nanna8 its important to be accurate with this whole thing and no countries have "called a halt". They have paused rollout while investigations are made.
No-one is dismissing any claims. No-one is saying its anyone's over active imaginations. There is however a lot of concern over the usual press approach which is making people think the vaccine is bad for them.
If countries decide to pause rollout because they think it is better to see some evidence before they go on, well good luck to them. Some European countries decided not to give the Oxford vaccine to over 65s. But have now started, of course. Netherlands have cancelled 43,000 appointments because of this. If I was in the Netherlands, I'd be spitting fire, actually.
I think you mentioned Thailand upthread? Well, they've started again. They've spent three days reassuring themselves that the data shows no adverse affects, which is what everybody thought would happen anyway. See attached, from the BBC site this morning.
