As the H5N1 avian flu continues to spread among dairy cows in the United States, nearly 5 million doses of flu vaccine are now being prepared for possible use in humans.

Since the outbreak in livestock began this spring, bird flu has been confirmed in three humans who worked on dairy farms in Texas and Michigan and health experts are concerned the virus could mutate to the point where it ...

Humanity's best protection against bird flu will be the development of effective vaccines, a new study says.

The H5N1 avian flu has been raging through cattle and poultry in the United States, increasing fears that the virus will make the leap into humans and potentially cause another pandemic.

An experimental mRNA vaccine against the H5N1 avian flu is highly effective in preventing severe illness and death in lab animals, researchers report.

The vaccine could help fight the H5N1 bird flu outbreaks now spreading in wild birds, poultry and cows in the United States, researchers said.

Development and uptake of the human papilloma virus (HPV) vaccine has been crucial in reducing rates of virus-linked cervical cancers in women.

Now, the accumulated data suggests the vaccine is saving men from fatal cancers, too.

Overall, men who got the vaccine [typically as boys]...

Powerful COVID vaccines could be setting people's immune systems up to successfully fight off not just future COVID variants, but other types of coronaviruses as well, a new study shows.

People repeatedly vaccinated for COVID -- the initial shots, followed by boosters and updated vaccines -- generate...

Babies born by C-section are unlikely to receive protection from a single dose of measles vaccine, a new study finds.

A single measles jab is up to 2.6 times more likely to be completely ineffective in C-section babies, compared to those born vaginally. Their immu...

Scientists are busy working on a vaccine that might fight strains of the COVID virus SARS-CoV-2 that haven't even emerged yet.

The effort from a British team at the University of Cambridge is already showing promise in mouse studies. Of course, mouse studies don't always pan out in humans, but study first author Rory Hills is optim...

Getting the HPV shot in adolescence can spare kids a lifetime of risk for cervical and other cancers related to the virus, but only half of American kids are up-to-date on these shots.

Now, a new review suggests that if schools mandate HPV shots as an entry requirement for students, immunization rates rise.

"A majority of studies evaluating HPV vaccine school-entry requirements fou...

Kids who don't like vaccination shots might soon have an alternative in a painless skin patch, researchers say.

More than 90% of 190 Gambian infants were protected from measles and all were protected from rubella after receiving a single vaccine dose through the ...

Live bird flu virus has not been found in any of the first batch of retail milk samples tested, federal health officials said Friday.

Amid an ongoing outbreak of bird flu in U.S. dairy cows, the early findings should reassure the public that the milk sold in stores remains safe, officials added.
