Cancer Vaccine Trial Raises Hopes for Treatment Beyond Melanoma
Scientists tested a vaccine called intismeran against melanoma, a type of skin cancer.
The trial was reported as successful on August 19.
Reports said the vaccine helped stop the cancer from returning.
This caused excitement about a possible new way to treat cancer.
Moderna’s shares reportedly more than doubled after the news.
Merck was also mentioned in headlines about the development.
However, it is not yet clear whether the vaccine will work for many other cancers.
The result may be an important breakthrough, but it could also be limited to melanoma.
