But you get MMR once, not once a year. And tetanus supposedly every 5 years (or is it 10?), but in practice for most people only when they get a puncture wound or bite.
The point is that if 'flu makes you ill off work for 10 days, and 10% of the population gets it per year, then the vaccine only has to make you ill off work for on average of 1 day before it's not economically viable.
And the whole point of vaccinating high risk groups is that if you do that, very few people will die of 'flu anyway. Inflicting a day or two of 'flu symptoms on the rest of the population every year may well not be worth the lives saved. In my view it's up to the population to decide whether they want to take their chances, because in the case of 'flu we don't need to care about population immunity.
