Author Interviews, Flu - Influenza, Pediatrics, Pediatrics, Vaccine Studies / 15.06.2020 Interview with: Allison Kempe, MD, MPH Ergen Family Endowed Chair in Pediatric Outcomes Research Professor of Pediatrics, University of Colorado School of Medicine Director of ACCORDS (Adult and Child Consortium for Health Outcomes Research and Delivery Science) University of Colorado School of Medicine | Children’s Hospital Colorado What is the background for this study? Response: In 2019 the WHO designated vaccine hesitancy as one of the ten leading threats to global health. Although studies have assessed parental vaccine hesitancy in different localities and estimated vaccine refusals nationally, there is little recent US national data on the prevalence of hesitancy about routine childhood vaccines and national hesitancy rates for influenza vaccine have never been assessed. We used a hesitancy scale developed by the WHO to estimate levels of parental hesitancy for both routine childhood and childhood influenza vaccination  (more…)
Author Interviews, CDC, Global Health, Infections, Vaccine Studies / 11.01.2019 Interview with: Kevin Chatham-Stephens, MD, MPH, FAAP CDR U.S. Public Health Service What is the background for this study? Response: Typhoid fever is a life-threatening disease caused by Salmonella Typhi bacteria. It spreads when someone consumes food or water that has been contaminated with feces (poop) from someone carrying the bacteria. About 12–27 million cases of typhoid fever occur worldwide every year. About 350 culture-confirmed cases of typhoid fever in the United States are reported to CDC each year. Most of these cases occur among international travelers. Symptoms of typhoid fever often include high fever, weakness, stomach pain, cough, and loss of appetite. Some people have diarrhea or constipation. Typhoid fever can be prevented through vaccination and safe food and water practices. Typhoid fever is treated with antibiotics, although most infections diagnosed in the United States cannot be successfully treated with the class of antibiotics called fluoroquinolones. (more…)
Author Interviews, Flu - Influenza, Vaccine Studies / 27.04.2016 Interview with: Dr Anna C. Phillips PhD CPsychol AFBPsS Reader in Behavioural Medicine School of Sport, Exercise & Rehabilitation Sciences University of Birmingham Edgbaston Birmingham What is the background for this study? What are the main findings? Dr. Phillips: We know that various factors can affect the response to vaccination and that older adults have a poorer response than younger people, i.e. they produce fewer antibodies.  We also know that many immune messengers and important hormones have daily rhythms in their levels and wanted to test whether the antibody response to vaccination might also be affected by time of day.  We randomised surgeries to giving morning or afternoon vaccinations and tested before and one month after the vaccination for levels of antibodies. Two of the three flu strains (viruses) contained in the vaccine showed a higher antibody response in the morning than in the afternoon, up to 4 x higher to one of the strains (A/California) and 1.5 x higher to the B strain. None of the potential mechanisms we measured (immune messengers, hormones) seemed to be driving this effect. (more…)
Author Interviews, Pediatrics, Vaccine Studies / 24.10.2014 Interview with: Louise-Anne McNutt, PhD Associate Director, Institute for Health and the Environment University at Albany, State University of New YorkLouise-Anne McNutt, PhD Associate Director, Institute for Health and the Environment University at Albany, State University of New York Jessica Nadeau, PhD Epidemiologist, University at Albany, State University of New YorkJessica Nadeau, PhD Epidemiologist, University at Albany, State University of New York Medical Research: What are the main findings of the study? Response: The study found that about 25% of infants consistently deviated from the routine vaccine schedule recommended by the American Academy of Pediatrics (AAP).  Alterations included either consistently refusing a recommended vaccine or reducing the number of vaccines given at each visit. These deviations are generally associated with intent to use an alternative vaccination schedule. Infants who did not follow the AAP recommended schedule were more likely to be unprotected against vaccine preventable diseases for a longer period of time. Only 1 in10 infants vaccinated on an alternative schedule were up-to-date at 9 months of age. (more…)
