A custom-made anti-tumor vaccine added to standard immunotherapy was twice as likely to shrink liver cancer as when a patient received immunotherapy alone, a new study shows.

The vaccine could help liver cancer patients live longer, as fewer than one in 10 survive five years after their diagnosis, the researchers noted.

In fact, about 8% of patients who received the new vaccine had ...

A pancreatic cancer vaccine has continued to protect a small group of patients from their cancer coming back, three years after receiving the jab, a new study says.

A new oral vaccine could prove a potential alternative to antibiotics for people with recurring urinary tract infections, a new study says.

More than half of patients with recurring UTIs (54%) wound up infection-free for nine years after receiving the oral spray vaccine, with no notable side effects, researchers report.

“Before having the vaccine, all our participants suffered fro...

Vaccine protection against mpox fades quickly in the human immune system, even in people who've received the full two-dose regimen, a new real-world study shows.

Antibody levels fell to low or near zero within the first few months of getting the vaccine, unless the person had previously received a smallpox vaccine, scientists reported Saturday at the European Congress of Clinical...

The COVID-19 virus can linger in the blood and tissue of patients for more than a year after they've shaken their initial infection, new findings show.

Researchers found pieces of SARS-CoV-2, the virus behind COVID, lingering in the blood for up to 14 months and in tissue samples for more than two ye...

There's more evidence bolstering the health effects of both breastfeeding and the COVID booster shot: Vaccinated, breastfeeding moms appear to pass COVID-fighting antibodies to their infants.

That's important, since babies under the age of 6 months aren't eligible for the COVID vaccine.

New research finds the 2022 mpox outbreak among gay and bisexual men began to slow down after just a few months -- even though just 8% of high-risk people had received the mpox vaccine.

That suggests that it was changes in gay and bisexual men's sexual behaviors, not the vaccine, that caused the outbreak to subside, researchers concluded.

"Once the mpox epidemic was recognized, beha...
