Swine flu vaccine - effectiveness?

No flu vaccine is 100% effective each and every time you receive it. You will see varying percentages depending on which site you go to but I believe the average is 70% effectiveness which means that your novel H1N1 vaccine will probably work just fine for you. Swine flu vaccines are for pigs. People receive novel H1N1 flu vaccines. Contrary to what "fototag" stated, it takes 2 weeks after receiving a flu vaccine to aculate sufficient antibodies to achieve full immunity, not 2 days.
