They can't make a cure-all but try to address the real nasty stuff that will kill an old person and/or really screw up an infant.....that sort of thing. They take their best SWAG and go with it. Sometimes the virus' we get are a little different than what the vaccine was targeted for and so we still get sick. We look at it as "sick is sick" and the shots are a waste of time.
Influenza outbreaks tend to follow generalized, world-wide patterns. Predictions are made- based on what is observed, many, many months ahead of our flu season. Vaccine production begins very early so that there is enough time to make an adequate supply.
My brother, a pediatrician, said today that while last year was mild, this year is terrible and is expected to become a full-fledged medical epidemic, possibly setting a record. Thankfully, the flues this year are milder and not very lethal than in years past.
There are presently three predominant influenza strains in circulation. This year's vaccine covered all three. The fourth predicted strain has not shown up. One can get sick from all three strains at the same time or in succession.
It is up to each individual whether the risk of the vaccine is worth taking when compared to the risk associated with the particular strains of influenza anticipated.
