Good work with all your summaries Steve, must've taken you a while!
The bike analogy is great, easily explains why the efficacy of the vaxs are dropping. I don't understand why they think boosters will work if it's still looking for the alpha variant, if it was a different product targeting delta then they'll make more sense for a booster.
I didn't get a chance to thoroughly read through the nurses testimony, can you tell me the site to go to please.
