Women getting vaccinated against the cancer-causing human papillomavirus (HPV) now need two or three shots, but an African clinical trial suggests a single dose is just as effective.

The finding could speed up the immunization process in developing countries with high levels of HPV-related cancers and protect many more women more quickly.

"These findings are a gamechanger that may s...

Protection can gradually fade after a second dose of the COVID-19 vaccine by Pfizer-BioNTech, which suggests that a booster shot might be necessary, researchers report.

They analyzed data from more than 80,000 adults in Israel, average age 44, who had no previous evidence of infection and who had received a PCR test at least three weeks after their second shot of the two-dose Pfizer vacc...

Republican lawmakers in several states are pushing vaccine mandate exemptions for workers who have so-called natural immunity due to a previous COVID-19 infection.

That's despite evidence that vaccination can reduce the risk of COVID-19 even for those with a history of infection, and the fact that there's no easy way to assess the protection provided by prior infection, CBS News ...

People will probably need regular booster shots for COVID-19 over the next few years to keep their immune systems on guard against a potentially deadly infection, an infectious disease expert says.

COVID mutations and high transmission rates in some parts of the country mean that even the vaccinated remain at risk for a breakthrough infection, said Dr. Jonathan Abraham, assistant professo...

COVID-19 booster shots trigger much stronger and longer protection than full vaccination with two doses of the Pfizer or Moderna vaccines, according to a small study.

It also found that the response to a booster is even greater in fully vaccinated people who have had infections.

"Because these antibody levels are so robust, the booster could potentially give us protection for a long...

Though airborne exposure causes most cases of COVID-19, the virus lurks on objects near the beds of infected nursing home patients, according to a new study.

    In the first wave, patients were...

    The COVID-19 pandemic has offered some lessons on respiratory disease transmission, and now a new review suggests that hospitals could use those insights to create even smarter infection-control policies.

    The review, published Nov. 9 in the Annals of Internal Medicine, suggests that some longstanding infection-control tactics at hospitals are "outdated."

    And certain changes, like gr...

    At a veterinary clinic in the United Kingdom, the staff noticed a sudden and atypical increase in cats and dogs who were experiencing myocarditis, an inflammation of the heart muscle.

    Was it a coincidence that these animals were showing up severely ill from a condition that has been linked to COVID-19 just as the highly contagious Alpha variant was circulating?

    Apparently not.

    Moms who had COVID-19 when they gave birth may help stimulate their infant's burgeoning immunity against the virus by breastfeeding, a small study hints.

    It's well known that breast milk contains certain maternal antibodies that can help protect infants from infections as their own immune systems develop.

    Studies indicate that's true of SARS-CoV-2, as well: Breast milk from moms who...

    The discovery that up to 80% of white-tailed deer in Iowa may be infected with COVID-19 has scientists worried that the animals could become a reservoir for variants that could come back to haunt humans.
