Im sure you all have read on Google News Heath that a couple of HIV vaccine trials have been stopped because it didnt look like the vaccines were offering any protection. I was interested in their operational definition of 'not working', as even a slight decrease in HIV infection rates in the vaccinated group vs placebo could mean there is something in the mix that is on the right track.
But this vaccine didnt work. It really didnt work.
Vaccine-- 24 infections out of 741Nothing.
Placebo-- 21 infections in 762
Vaccine + boosters-- 19 infections in 672
Placebo + 'boosters'-- 11 infections in 691
Not even close to being on the right track.
