Well good for them. Vaccines might work but until there is open discussion of the harm they can do and the mechanism for this harm and some nuance around who is at most risk and what we can do to mitigate that risk, telling people that vaccines work will not convince many more people to roll up their sleeves. The messaging is missing the mark, because it requires discussion, not chants of 'vaccines work'.
I've no doubt that vaccines work, but given the harm they've done around me it's a hard no from me.
