National Influenza Vaccination Week 2014: Interview with HHS Region 3 Administrator Paxman

Dalton G. Paxman, PhD, FCPP For National Influenza Vaccination Week, I had the pleasure of interviewing Dalton G. Paxman, PhD, FCPP, Regional Health Administrator for the mid-Atlantic region, where he oversees public health initiatives for the Office of the Assistant Secretary for Health (OASH), U.S. Department of Health and Human Services (HHS). Dr. Paxman is a Fellow here at The College of Physicians of Philadelphia. Influenza season has begun – has there been much influenza nationally yet? What kind of activity are we seeing in HHS Region 3? Flu activity is beginning to increase in parts of the United States and CDC is getting reports of flu illnesses, flu hospitalizations, and flu deaths. Influenza A (H3N2) viruses are most common so far. H3N2 predominant seasons are associated with more severe illness and mortality, especially in older people and young children, than during H1N1- or B-predominant seasons. If H3N2 viruses continue to predominate, this season could be severe. More

National Influenza Immunization Week 2014

Photo courtesy CDC It's National Influenza Immunization Week, an observance sponsored every year by the CDC to highlight the national immunization influenza vaccination recommendations. For the past several years, all US individuals in the United States over 6 months of age have been recommended by the Advisory Committee on Immunization Practices to get the influenza vaccine. This influenza season has already been eventful, not only in terms of morbidity and mortality, with five pediatric deaths reported, but also in terms of questions about influenza vaccination effectiveness. First, earlier this fall CDC announced a puzzling finding: in certain groups of children during the 2013-14 flu season, the live attenuated influenza vaccine was less effective against the circulating H1N1 virus than the inactivated vaccine. This finding was unexpected because the live vaccine has in other seasons provided superior protection than the inactivated vaccine.  More

Influenza Vaccine Clinic Here at the College

Our Director of Communications gets his flu shot Here at The College of Physicians of Philadelphia we have about 44 full- and part-time staff people. When a cold or the flu is going around, 10% to 20% of staff can be at home sick. That makes staffing a challenge, particularly because we have to have enough personnel here to sell tickets to the Mütter Museum and staff the museum store. In winter 2013, I polled the employees here and found that only 43% had gotten the flu vaccine in the 2012-13 season. To try to boost our uptake of the vaccine, in fall 2013 I organized a flu vaccine awareness campaign. The result was that about 70% of staffers got the vaccine for the 2013-14 season. This year we decided to reduce all the barriers to vaccination (the trip to the doctor or the pharmacy, needing one's insurance card, inertia), and we brought a pharmacist here to give the trivalent inactivated influenza vaccine to any staffers or contractors who wanted it. As an incentive, and like last year, we gave a $10 Trader Joe's gift card to anyone who got the vaccine. More

From ID Week: Adult Immunization Barriers and Promoters

How is the immune system similar to your marathon time? As we age, our immune response decreases at the same slope that our marathon race times increase. Presenters laid out this and some of the other problems of immunizing adults in the Symposium on Adult Immunizations, an early session at the Infectious Diseases Society 2014 conference at the Philadelphia Convention Center. Kenneth Schmader, MD, noted that though adults age differently – some adults at age 75 may be running marathons while others may be frail – all are subject to immune system senescence, and all are vulnerable to rapid functional declines that may result from an acute stressor, whether it’s a fall or a debilitating case pneumococcal pneumonia.

Flu Vaccine: How Did We Do?

Flu Vaccine Field Trip Last year I informally surveyed my co-workers here at The College of Physicians of Philadelphia to find out how many, in this organization whose mission is in part to “advance the cause of health,” had taken the influenza vaccine that season. Out of the 30 people I polled, 43% had. Though this was about on par with national flu vaccine uptake, I was still disappointed with the low number. And so this year, with my supervisor's encouragement, I decided to do something. In early October I spoke briefly at an all-staff meeting to talk about benefits, risks, and myths of influenza vaccination. More than that, though, I promised a $10 Trader Joe’s gift card to everyone who’d get vaccinated and show me the proof. More

NIVW is a national observance that was established to highlight the importance of continuing influenza vaccination, as well as fostering greater use of flu vaccine after the holiday season into January and beyond. Dr. Paxman is a Fellow here at The College of Physicians of Philadelphia. His biographical information is below. Many thanks to Dr. Paxman and to Mahak Nayyar, MPA, FCPP, Deputy Regional Health Administrator, for her coordination. More

Universal flu vaccine for health workers?

Influenza ward, 1918/19, US Army, Langres, France. NLM. Today’s blog post is by History of Vaccines advisor Thomas Fekete, MD, FCPP. Dr. Fekete is infectious diseases section chief at Temple University School of Medicine. This piece follows my post from Tuesday, which looks at mandatory influenza vaccination policies and implementation at Childrens Hospital of Philadelphia and other area health systems. In the community, influenza can be transmitted at home, at school, at work or in other public venues. During the influenza pandemic of 1918-1919, large public events in cities like Philadelphia were followed by enormous waves of influenza illness and death. More

Healthcare Worker Influenza Immunization: Mandates, Benefits, Consequences

Asian Flu Vaccine, 1958 As influenza season approaches, many hospitals and health systems are asking their staff to take the influenza vaccine. Some merely suggest or recommend it, but others mandate it. Consequences for noncompliance range from having to wear a mask during patient care encounters during the influenza season to termination of employment. The reasoning behind requiring health care worker (HCW) influenza immunization relates to possible effects on outcomes related to the hospital environment and patient care, such as preventing spread of influenza to patients, worker absenteeism during busy influenza season, and modeling preventive health behaviors to patients.

Notes from Vaccine Update Webinar with Paul Offit, MD

On March 13, the Children’s Hospital of Philadelphia Vaccine Education Center sponsored a vaccine update webinar with Paul A. Offit, MD, as the speaker and moderator. Dr. Offit discussed vaccine-related items in the news as well as decisions taken at recent Advisory Committee on Immunization Practices (ACIP) meetings in Atlanta. First on the agenda was a discussion of pertussis vaccine, particularly as it relates to a February 7 letter to the New England Journal of Medicine in which researchers (Queenan, Cassidy, & Evangelista) called attention to new strains of Bordatella pertussis that the group had observed at St. Christopher’s Hospital in Philadelphia. Specifically, these strains were classified as pertactin-negative. Pertactin is a protein that is normally a component of B. pertussis, and it is one several antigenic proteins in acellular pertussis vaccines. The letter questioned whether the acellular vaccine was generating pressure on B. pertussis, thus leading to the emergence of these pertactin-negative strains. More
