With about 14 million new infections a year, human papillomavirus (HPV) is the most prevalent sexually-transmitted virus in the United States.
HPV has long been linked to cervical cancer. Certain strains of the virus cause an estimated 12,000 cases of cervical cancer annually among women in the U.S. Now, rising rates of HPV-linked mouth and throat cancers – known as oropharyngeal cancers – are receiving increased attention, as are efforts to get Americans up to age 45 vaccinated to reduce the spread of HPV-related diseases.

Ongoing trade tensions between the U.S. and China are having an impact on the global economy and potentially U.S. biosecurity.
Late in the summer of 2018, New York Times reporter Emily Baumgaertner authored a story breaking the news that China had stopped providing samples of a flu virus – named H7N9 – with U.S. health authorities. The H7N9 bird flu [the influenza virus is named with H’s and N’s based on their protein makeup] has been circulating in China since 2013 and has spread through poultry farms. Continue reading
This year’s severe flu season has increased the spotlight on the development of a “universal” influenza vaccine – a vaccine that would be effective against most strains of the flu.
But that vaccine has been elusive.
In 2011, Francis Collins, director of the National Institutes of Health, told USA Today that he was “guardedly optimistic” a universal flu vaccine would be within reach in five years after scientists identified pieces of the virus that consistently appeared in seasonal and pandemic flu viruses.

When was the last time you thought about shingles? Not the ones you put on your roof, but the itchy, burning, painful rash that affects about a million older adults each year. For some people, shingles can be downright dangerous. So why aren’t more older adults getting vaccinated?
As Paula Span wrote in this New York Times article, “People once vigilant about vaccinating their children are not nearly as careful about protecting themselves as they age, even though diseases like influenza, pneumonia and shingles (aka herpes zoster) are particularly dangerous for older people.” Continue reading
On MSNBC.com, University of Pennsylvania bioethics professor Arthur Caplan takes a tough stand on flu vaccines for health professionals, imploring them to stop “whining” and “moaning.” “Doctors, nurses, respiratory therapists, nurses’ aides, and anyone else who has regular contact with patients ought to be required to get a flu shot or find another line of work,” Caplan writes. According to Caplan, a 100 percent workers’ vaccination rate can cut patient flu deaths and worker sick days by about 40 percent, and thus health workers who claim mandated flu shots are an infringement of their rights are forgetting a key ethical tenet of their profession, that they put the interests of the patient above their own.
It’s the idea of rights infringement that really sets Caplan off:
Excuse me? What rights might those be? The right to infect your patient and kill them? The right to create havoc in the health care workforce if swine flu hits hard? The right to ignore all the evidence of safety and efficacy of vaccines thus continuing to promulgate an irrational fear on the part of the public of the best protection babies, pregnant women, the elderly and the frail have against the flu? Those rights?
Caplan’s a fellow and former associate director of the Hastings Center, a nonpartisan bioethics think tank.
A just-released survey conducted by the American Society of Health-System Pharmacists finds that health workers are asking pharmacists the same questions (PDF) that patients are asking:
- Is the H1N1 vaccine safe? (Patients: 52%, Hospital Employees: 54%)
- Do I need to get the H1N1 vaccine? (Patients: 33%, Hospital Employees: 43%)
- Will there be enough H1N1 vaccine to around? (Patients: 27%, Hospital Employees: 27%)
The ASHP also says that “While pharmacists are authorized to administer vaccinations to adults [in most states], the survey also finds that most hospitals are not planning to utilize pharmacists for this service. ” The organization – made up of 35,000 members who include pharmacists, pharmacy technicians and pharmacy students – is encouraging hospitals and health systems to use pharmacists to administer vaccines to increase vaccination rates. The survey also looks at other H1N1 influenza preparedness issues as well.
If all goes well, a vaccine against the H1N1 flu virus could be available for widespread use by October.
The Centers for Disease Control and Prevention shipped samples of the swine flu virus to companies working on the vaccine a few days ago, Reuters reports.
Several companies, including AstraZeneca’s MedImmune unit, have begun working on the vaccine. Pilot batches could be ready in a few weeks for testing in people over the summer. Those trials would help determine the right dose and whether an adjuvant is need to get the right response. The feds have committed $1 billion to aid vaccine development.
An adjuvant, or immune-system booster, might also be used to stretch the supply of vaccine so that the batches produced could protect more people, a CDC official told Reuters.
Separately, China released a group of school children from Maryland who had been held in quarantine since arriving in the country on a trip a week ago. Meanwhile, Chinese authorities reported the first case of swine flu transmitted from one person to another inside the country.
