It found the vaccine reduced the chance of getting laboratory confirmed influenza from 23 cases out of 1,000 to 9 cases out of 1,000.
While this seems to be a reduction of more than 50%, that seems less optimistic expressed in absolute terms.
The infection rate in adults drops from 2% per year to 1%. You could say that’s halved, but it effectively only drops by 1%. So this means that out of every 100 healthy adults vaccinated, 99 get no benefit against laboratory confirmed influenza.
