I think they’ve seen a lot of data, the question is have they seen enough data? It’s far too simplistic to say these drugs have been tested enough and far too easy to take a polarised view which says anyone not taking a vaccine is an anti vaxer.
I would prefer to state a view that under normal circumstances these drugs would have several years of investigation before coming to market but these are not normal circumstances. The question then becomes one of whether the risks of taking the vaccine both at an individual and macro level outweigh the risks of not taking them? My view is that it is a risk well worth taking.
Fast forward 30 years and post a scenario where there may be side or long term effects, without speculating exactly what they are. Is the world going to remember the decisions that were taken and the reasons for those decisions or is it just going to sue the crap out of each other?
