Daphne the problem with 'flu is that it is not a single illness like diptheria it is a virus that mutates and changes over time. The vaccine is a "best guess" about which strains will be active in any year. There is no vaccine for a cold because over 250 variations of the cold virus are in circulation. So you may think your flu vaccine protects you but it may not. The argument about wiping it out like diptheria is unfounded. In fact there is some evidence that the virus is mutating more rapidly.
