Stem cells had greater effect than differentiated tumor cells in eliciting antitumor immunity in vivo. Antibodies and T cells targeted cancer stem cells in laboratory models. Data could provide a rationale for a new type of immune therapy.

Women who have been infected by two different strains of HIV from two different sexual partners – a condition known as HIV superinfection – have more potent antibody responses that block the replication of the virus compared to women who’ve only been infected once.

Researchers are closing in on a needle-free vaccine for respiratory syncytial virus (RSV), a major cause of respiratory illness in children under two years of age.

Tobacco plants responsible for millions of smoking deaths each year could become a public savior by transforming into living factories for making vaccines.

Researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus.

Scientists have developed a vaccine that has protected nonhuman primates against multiple exposures to simian immunodeficiency virus (SIV) given in three clusters over more than three years. SIV is the nonhuman primate version of HIV.

Recent research found that microneedle vaccine patches are more effective at delivering protection against influenza virus in mice than subcutaneous or intramuscular inoculation. A new, detailed analysis of the early immune responses helps explain why the skin is such fertile ground for vaccination with these tiny, virtually painless microneedles.

Researchers have made the discovery of a vaccine that will potentially help combat hepatitis C.

Scientists have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were 'so to say' vaccinated with their own cells. The immune system of the testees was better than before in attacking and suppressing the virus, the scientists have reported.

Experts now recommend that pre-teen boys get vaccinated against HPV, that 16-year-olds receive a meningitis booster shot, and that almost all children receive a flu shot annually.

The vaccines of the future against infections, influenza and cancer can be administered using an electrical pulse and a specially-produced DNA code, new research suggests. The DNA code programs the body’s own cells to produce a super-fast missile defense against the disease, researchers say.

Scientists have developed a new vaccine to treat cancer at the pre-clinical level. They developed a new approach for treating the disease based on manipulating the immune response to malignant tumors.
