My family Doctor recommends me to take a flu shot vaccine every year to prevent getting the flu but I still end up with the flu eventually. Twice a year I fall sick in spite of taking the flu shot. But if I don't take the flu shot it could have been worse for me I guess.
What I understand it the way this flu shot works is that the vaccines contains a small trace amount of the actually dead flu virus. So when that vaccine is injected into our body, our body starts producing Anti-Bodies to fight the invading dead virus. Although the virus is dead but the body recognise it as alive and starts the production of antibodies. Then when the actual virus attacks our body during the winter months, our bodies will have enough antibodies to fight the actual virus. What I don't understand is that why I still fall sick in spite of me taking the yearly flu shot vaccines.
