The U.S. Food and Drug Administration's vaccine advisory panel on Thursday voted unanimously to recommend that the agency phase out original versions of COVID vaccines for use in the unvaccinated, in favor of updated bivalent booster shots.

Committee members also weighed a proposal to streamline the dosing schedule for COVID vaccines by turning them into annual shots that would likely be ...

In a finding that suggests the updated bivalent COVID booster shots are worth getting, new government data shows they cut the chances of infection with the new XBB variant by nearly half.

While those ages 49 and under saw a 48% reduction in risk, the shots were slightly less effective in older individuals -- about 40% in adults ages 50 to 64 and 43% in those 65 and up. Effectiveness was s...

The U.S. Food and Drug Administration on Monday asked its vaccine advisory panel to weigh a proposal to turn COVID vaccines into an annual shot for most Americans.

The committee will weigh the proposal at its Jan. 26 meeting.

Such a move would simplify future vaccination efforts, a critical point given the fact that efforts to get people to get COVID booster shots have fallen far sh...

The new coronavirus continues to dodge, duck, dip and dive, mutating again and again to find its way past people’s immune defenses.

The latest COVID variant to gain a foothold in America is called XBB.1.5, which has rapidly started to crowd out other competing variants.

XBB.1.5 is the first recombinant COVID variant expected to become dominant in the United States, according to th...

In yet another setback for the future of HIV prevention, the only HIV vaccine in a late-stage trial has failed, study leaders announced Wednesday.

Launched in 2019 as a partnership between the U.S. government and the pharmaceutical giant Janssen, the Mosaico trial was being conducted in eight European nations and the Americas, including the United States. Researchers had enrolled nearly 3...

A new study shows that many women diagnosed with and dying from cervical cancer are older than 65 -- a group for whom routine screening is usually not recommended.

Cervical cancer screening has been credited with a sharp drop in deaths from the disease in the decades since it was introduced in the United States. But current guidelines state that once a woman reaches 65, if she has been re...

Vaccinations among kindergarteners declined for the second year in a row, leaving hundreds of thousands of young children vulnerable to dangerous infectious diseases, U.S. health officials reported Thursday.

    Despite routine use of a childhood vaccine, the United States still sees outbreaks of mumps. Now, a new study reinforces the belief that it's due to waning immunity post-vaccination.

    Mumps is a viral infection best known for causing puffy cheeks, a swollen jaw, fever and general misery. While it's usually relatively mild, mumps occasionally causes serious complications like brain inflamma...

    COVID-19 patients could soon have a new antiviral pill they can take to guard against severe disease.

    The treatment, called VV116, worked as well as Paxlovid in people who were at high risk of severe disease in a phase 3 trial in China.

    The trial was a “great success,” study co-author Ren Zhao, a professor at Shanghai Jiao Tong University School of Medicine, said in a

    Young cancer survivors face a heightened risk from human papillomavirus (HPV), a virus known to raise the risk of cervical cancer. So why are they getting the HPV vaccine in low numbers?

    To find out, researchers analyzed data from a clinical trial of the HPV vaccine among cancer survivors who were ages 9 to 26 and were one to five years from the completion of their cancer treatment.

  • COVID-19 vaccination is more effective than natural immunity when it comes to keeping you out of the hospital, a major, real-world study has found.

    People of all age groups benefited significantly more when they got the jab than if they acquired immunity through a COVID infection, researchers report.

    Rates of hospitalization and death for any reason -- not just COVID -- were 37% low...

    Researchers report they have created a vaccine to fight fentanyl addiction, in a potential breakthrough in the opioid epidemic.

    The shot would block the ability of fentanyl to enter the brain and cause the “high” that users crave. It could be used to prevent relapses in people trying to quit opioids, once it gets through clinical trials, the scientists said.

    It's a troubling equation: Many Americans with the highest rates of hospitalization for influenza have the lowest uptake of the annual flu vaccine.

    That's why the U.S. Centers for Disease Control and Prevention is stepping up outreach to minority communities, including Black, Hispanic and American Indian/Alaska Native (AI/AN) groups, and working to reduce barriers to vaccination.

    ...

    While a large number of Hispanic Americans have received at least one dose of a COVID-19 vaccine at this point, a new study suggests barriers may still stand in the way for those who might want to get shots.

    Researchers identified four key barriers to vaccination: a...
