Researchers at Harvard Medical School (HMS) have found that a method they developed for vaccinating organisms against harmful foreign cells and viruses could one day help lead to a cancer vaccine.
There's reason to believe that the principle could bear real fruit. About 20 of the 100 or so strains of HPV have been linked to cervical cancer, but 70% of cervical tumors are caused by just two strains--HPV-16 and HPV-18. Koutsky and her colleagues focused on...
So far, the most common side effect of the prototype vaccine has been a little bit of muscle pain at the injection site. The inoculum was designed so that it cannot cause an HPV infection, even accidentally. It contains only proteins from the virus' outer shell and no genetic material...
Merck is moving forward with plans to test a more refined vaccine that may be available in five years. (Other groups are pursuing similar strategies.) Such a vaccine would protect against the two main cancer-causing strains of HPV as well as HPV-6 and HPV-11, which are not...
Researchers have yet to determine how long the anti-HPV protection of any vaccine would last and how many lesions it would prevent. It's already clear that the Merck vaccine would not be of much help to women who have previously been exposed to HPV. For any mass-inoculation...
