Best Answer

The vaccine puts dead flu cells into your body. Because the cells are very weak, you immune system can completely kill that virus. After you immune system kills the virus, antibodies are still left over in your blood stream. So, if you are exposed to the flu, the already made antibodies can kill the flu virus before it spreads and gets too serious for your immune system to overcome.

No, a flu vaccine triggers our bodies to make our own antibodies. The vaccine includes dead or weakened viruses that can't make us sick, but they will cause the immune response that creates the correct antibodies.

Why would you have to get the H1N1 shot?

Hey there fellow user! Firstly, it is called the flu shot which contains the 3-4 flu virus strains predicted by scientists every year all over the world. And of course, the H1N1 2009 pandemic strain will always be in that cocktail. There are MANY flu virus strains that are currently circulating, and the vaccine sometimes prevents you from getting sick. On the other hand, you might manage to get a little sick from the other strains which are not present in the vaccine to give you immunity. Predictions can sometimes go wrong so that's how the flu vaccine can occasionally fail. On the bright side, you are resistant to those strains you got vaccinated against which is not a waste at all so don't skip them! But, you must take precautions like handwashing, wearing a mask when sick or if someone who you know is sick, and cleaning surfaces touched by a sick person during flu season. And if you are sick, stay at home till you fully recover so you don't make others sick. This may seem pretty long, but I hope you are happy with this response! 😄
