I see nothing there about cancer - it is someone's research and theores.
I'm sorry to hear about the young lady.
Vaccines for cervical cancer are being used for prevention.

Vaccines, in clinical trials are investigational.

"Cancer vaccines have been researched for a number of years. Some studies
in laboratory animals (such as mice) have shown promising results, in
which vaccines have successfully stimulated the immune system. Research
has not always been so successful in humans. Recently studies have shown
more encouraging results however.

The reasons why previous studies have been unsuccessful are not fully
understood. A number of theories have been suggested however, which
include:

   * many people with cancer have reduced immunity and so their immune
systems are not able to react to the vaccines
   * some tumours produce proteins and chemicals that prevent the immune
system from attacking them effectively, even when it has been stimulated
by the vaccine
   * not all tumour cells are the same and some cells may be different to
those in the vaccine. Those different cells will be resistant to, and
unaffected by, the vaccine."

If she only has a few months, look to palliation and quality of life for
her, please.
