MedicalResearch.com Interview with Eric S. Weintraub, M.P.H. Epidemiologist at Centers for Disease Control and Prevention MedicalResearch.com: What are the main findings of the study? Mr. Weintraub: While current rotavirus vaccines were not associated with intussusception in large pre-licensure trials, recent post-licensure data (from international settings) suggest the possibility of a low risk of intussusception occurrence after receipt of monovalent rotavirus vaccination (RV1).  We examined the risk of intussusception following RV1 vaccination in a U.S. population.  In this study of more than 200,000 doses of RV1, a slight increased risk of intussusception was observed after vaccination, which should be considered in light of the benefits of preventing rotavirus associated illness.

Ghassan Dbaibo, M.D., FAAP Professor and Vice-Chair for Research and Faculty Development Department of Pediatrics and Adolescent Medicine Head, Division of Pediatric Infectious Diseases Director, Center for Infectious Diseases Research Professor, Department of Biochemistry and Molecular Genetics American University of Beirut Beirut, LebanonMedicalResearch.com Interview with: Ghassan Dbaibo, M.D., FAAP Professor and Vice-Chair for Research and Faculty Development Department of Pediatrics and Adolescent Medicine Head, Division of Pediatric Infectious Diseases Director, Center for Infectious Diseases Research Professor, Department of Biochemistry and Molecular Genetics American University of Beirut Beirut, Lebanon MedicalResearch.com: What are the main findings of the study? Dr. Dbaibo:
  • 55% efficacy (95% CI 39–67%) for prevention of all influenza
  • These results are comparable with other estimates of efficacy and effectiveness for trivalent inactivated flu vaccines in this age group
  •  73% efficacy (97.5% CI 47–86%) for prevention of moderate-to-severe influenza
  • By preventing moderate-to-severe influenza, vaccination prevented the most clinically consequential outcomes of infection, reducing hospitalisations by 75% and medical visits by 69%.
  • Seroprotection rates of more than 95% for each of the four influenza strains in the vaccine
  • An acceptable safety and reactogenicity profile (more…)

Dr Belén Pedrique Epidemiologist Drugs for Neglected Diseases initiative DNDi, 15 Chemin Louis Dunant 1202 Geneva, Switzerland MedicalResearch.com Interview with : Dr Belén Pedrique Epidemiologist Drugs for Neglected Diseases initiative DNDi, 15 Chemin Louis Dunant 1202 Geneva, Switzerland MedicalResearch.com : What are the main findings of the study? Dr. Pedrique: Of the 850 new drugs and vaccines approved for all diseases in 2000-2011, 4% (37) were for neglected diseases, defined broadly as those prevalent primarily in poor countries: malaria, tuberculosis, 17 neglected tropical diseases (NTDs) as defined by the World Health Organization (WHO), 11 diarrheal diseases, and 19 other diseases of poverty, excluding HIV/AIDS. Globally these neglected diseases represent an 11% health burden, based on a recent assessment of 2010 disability-adjusted life-years (DALYs). Most newly developed therapeutic products were repurposed versions of existing drugs. Of the 336 brand-new drugs (new chemical entities, or NCEs) approved for all diseases in 2000-2011, only four, or 1%, were for neglected diseases; three were for malaria, and one for diarrheal disease. None were for any of the 17 WHO-listed NTDs Of 148,445 phase I-III clinical trials registered as of Dec 31, 2011, only 1% (2,016) were for neglected diseases. (more…)

MedicalResearch.com Interview with: Dr. Ali Rowhani-Rahbar PhD, MD, MPH Kaiser Permanente Vaccine Study Center, Oakland, California University of Washington Department of Epidemiology Health Sciences Seattle, WA 98195Dr. Ali Rowhani-Rahbar PhD, MD, MPH Kaiser Permanente Vaccine Study Center, Oakland, California University of Washington Department of Epidemiology Health Sciences Seattle, WA 98195   MedicalResearch.com: What are the main findings of your study? Answer: We found that the magnitude of increased risk of fever and seizures following immunization with the first dose of measles-containing vaccines during the second year of life depends on age.  Specifically, the risk of seizures attributable to the vaccine during the 7 to 10 days following vaccination was significantly greater among children 16-23 months of age (9.5 excess cases per 10,000 doses) than among children 12-15 months of age (4.0 excess cases per 10,000 doses).

Answer: This is a Swedish/Danish population-based study comparing serious disease outcomes in girls immunized with the quadrivalent HPV vaccine against the unvaccinated population. The main finding of this study was that none of the 53 outcomes included in the study were more common in the vaccinated population compared to the non-vaccinated population. (more…)

MedicalResearch.com: What are the main findings of the study? Answer: From this trial, the inactivated alum-adjuvant EV71 vaccine showed a good protection for both the EV71-associated HFMD and EV71-associated disease. The vaccine gave 90% protection against clinical EV71-associated HFMD and 80.4% against EV71-associated disease (including neurological complications) for at least 12 months. The safety profile and immunogenicity of this vaccine is proved to be clinical acceptable. We also proposed a titre (1:32) of neutralization antibody as surrogate of protection against EV71-associated disease.
