Interestingly, there's no call for a booster on the J&J, which was trashed by the media earlier.

This is becoming a marketing windfall for vaccines that perform poorly. In educational technology parlance, this is what is referred to as rewarding poor performance.

I think you might have got the best one - only one shot - not known for extreme side-effects - greater durability - though i haven't seen studies one way or another on that i should add. Unfortunately it's not available here.

Meanwhile, things must be getting serious in the UK. Apart from break-through infections, there was a 'break-through' article in the BBC that has broken radio-silence to admit, for the first time, the possibility that vaccines might be failing.

It also points out the illogic of vaccinating children with partially effective vaccines when you would get a far better immune response if you just let them catch Covid - and build a natural resistance as they grow up.
