To viruses and bacteria the human body is like a buffet table. If one virus is eliminated, another virus will evolve to take its place. Already we have acute flaccid paralysis, a disease with the symptoms of polio that is not caused by the polio virus. Although we can celebrate our successes, we shouldn't imagine we can eliminate all childhood diseases through vaccination programs. |
