But, from what I have just read, of those 40% vaccinated the vaccine will only be effective for an
average of 45% when taking all age groups into account. It will be most effective for the young (65% average apparently) and least effective for the elderly (16% was quoted in the paper I read). Those figures, which I was never aware of previously, don't comfort me. I guess ignorance (on my part) was bliss.
