Swine Flu Vaccine

For my world news article I read U.S. to share swine flu vaccine globally by Associated Press. It talks about how we are going to share the vaccine of swine flu, also called H1N1 virus, worldwide. If they go through with this then I think it would be a great accomplishment for not only the United states but for other countries. The World. the United States says that they are working with other countries, Austrailia, Brazil, France, Italy, New Zeland, Norway, Switzerland and the United Kingdom, and sharing different vaccines. that is the part that struck me. Why does the world have multiple vaccines? What if one of them doesn't work? Why cant the world just have one super vaccine? I think that they should make it a law or something that you have to go to the doctor about once a month to check if you have swine flu until the epidemic is cured. School and other major things are getting shut down because of it. At Hospitals if you don't get a flu shot by a certain time then you have to wear a mask. At church one day, we couldn't even make physical contact because a kid at 6the church's school was infected. If we find a cure for this then there would be no more school shut downs. t would be a huge success.
