Routine vaccines are usually effective, such as DPT (diphtheria pertussis tetanus) and MMR (measles mumps rubella). These are usually taken in one course during childhood, and sometimes with boosters once a decade in adulthood.
Seasonal influenza vaccines are often ineffective, due to antigenic drift as the hundreds of unique influenza virus strains constantly mutate. This is why there is a flu season in the first place, with new flu vaccines marketed annually, as researchers try to guess how to combat the new strains in a given year. Getting a flu shot is no guarantee of not getting the flu.
