The idea is that the vaccines will train T cells to spot cancer, while the antibody will make sure the T cells remain activated long enough to do their dirty work.
Researchers believe these new antibodies promote the production of a mysterious class of immune system cells called regulatory T cells that act as peacekeepers to ensure the rest of the immune system's soldiers remain under control.
Like most physicians, Bolli was taught that heart cells don't regenerate, and that any cells which die from loss of oxygen during a heart attack are lost forever.
And the more money we're putting in, they're starting to come up with drugs that only kill the cancer cells and don't kill healthy cells, or that can be tailored to a particular kind of cancer that's matched up because of new genetic information.

Just what causes T cells to malfunction in people with psoriasis isn't entirely clear, although researchers think genetic and environmental factors both play a role.
They include compounds that block bad genes responsible for spreading cancer into the bones, chemicals that prompt prostate cancer cells to destroy themselves and vaccines that train the body's killer T cells to seek and destroy tumor cells.
But Mitalipov says his process with the human cells isn't designed to generate a human clone, but rather just to create the embryonic stem cells.
Mice given the modified cells produced more than six times the number of "killer T" cells, which are immune cells produced to neutralise a target.
But creating a cloned embryo requires human egg cells, and egg cells aren't cheap.
The laborious process entails isolating a patient's T cells and inserting a new gene.
The T cells, Lieberburg says, seem to be the culprits behind the brain inflammation.
After removing a growth in her thyroid gland, doctors concluded that cancer cells weren't present.
In a cruel twist, the body's disease-fighting T cells attack healthy skin cells, misidentifying them as foreign.
It will be tricky engineering T cells to survive inside the body long enough to destroy the cancer.
But it also spurred the body to send out T cells, predatory immune cells that hunt down infection.
He is one of a handful of researchers attempting to reprogram a patient's own T cells to attack cancer.
Normally, T cells travel throughout the body to detect and fight off foreign substances, such as viruses or bacteria.
When they hooked up with CD-2, the decoys prevented the real LFA-3 from binding to and activating the T cells.
In 1987 Biogen and Harvard University scientists were experimenting with a receptor called CD-2, situated on the surface of T cells.
Someday he envisions cancer centers storing giant banks of premade T cells to match the patients' bone marrow and tumor types.
One reason for the limited response rate may be that some patients' T cells do a poor job of recognizing melanoma.
Ultimately, researchers will likely want to combine it with one of the vaccines being developed to stimulate production of killer T cells.
But during an illness, or when the immune system goes haywire in autoimmune diseases such as diabetes, the attacking T cells take over.
The modified T cells are grown outside the body for several weeks until billions of them are ready and are then injected back into the patient.
The biggest is why the new technique is able to make T cells unresponsive to just the specific tissues that are initially transplanted.
In addition, other types of cancer can interfere with the activation of "killer T cells" - immune cells which arrive to destroy tumour cells.
If you have psoriasis, however, the T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection.
Their experiments on mice showed the virus impaired the ability of a specific part of the immune system, called regulatory T cells, to calm inflammation.
After removing a growth, doctors concluded that cancer cells weren't present.
"We thought maybe we should look at T cells, " says Alice Gottlieb, a psoriasis expert and director of clinical research at UMDNJ-Robert Wood Johnson Medical School.
