Yeah, the AtraZeneca vaccine suspension reeks of politics more than science. The EU doesn't want to be seen to have been dependent on the UK.
To have 30 people develop some symptom out of 17 million means that if anything the vaccine reduced the rate rather than increased it as you'd expect far more people to just develop it anyway out of that many.
Personally, I like the look of the J&J vaccine simply because you only have to make one trip. Here in Canada it's completely fucked up and they are trying to cover their ineptitude by claiming that you don't need the 2nd dose of the 2-dose vaccines anyway, to stretch things out. Doesn't seem to be "follow the science" to not follow the damn label.
Ultimately, they all reduce the probability that you will contract Covid and also reduce the symptoms of it if you do. So there is still value to social distancing and mask wearing even if you are vaccinated in order to reduce spread, especially while not everyone will have had the vaccine - it would be unfair for those who have benefitted from early vaccination to also then possibly put others at greater risk.
