How is requiring more data than the USA, UK and 27 states of Europe not a roadblock?
There's a set of data that every vaccine needs to get approval by the MHRA, FDA and EMA, that's been provided, and they have decided it's not enough.
How do you know they require more data than others? You keep saying that but is there any implication that they do? I'm no expert but surely preexisting health conditions is a ridiculously normal thing to consider? Genuinely not trying to be awkward. Just confused by your assertion that the Swiss are putting up roadblocks based on...well, one very standard question.
Edit - given that the UK is the only one to approve it so far im not sure you can say the Swiss are being any different to other European countries. If that changes fair enough. Currently we're the outlier.
