Risk and Reward

"Fears over cancer vaccine as schoolgirl dies"
http://www.cnn.com/2009/WORLD/europe/09/29/hpv.vaccine.explainer/index.html

After a 14 year old dies just hours after receiving the much talked-about HPV vaccine, England has halted all vaccinations in the program that has become mandatory since the recent development of the cancer preventative procedure. Although the autopsy confirming cause of death has yet to be performed and released, the sobering occurrence raises important issues. Though this seems to be a very rare case in the nationwide program, one has to wonder, is preventing cervical cancer worth risking death at a young age? How are these vaccines developed and tested to begin with? What are the hidden side effects that we may not be aware of, and will there be unforseen long term impact? Exactly how effective will this vaccine be 30 years from now? Personally, I have already received this vaccine and was completely fine, but will this be the case years from now? Hopefully these issues will be addressed in the near future.
