We assessed the effectiveness of shingles vaccine in preventing incident shingles among Alberta residents aged 50 years or older over the period 2009 – 2015, using administrative health data.The cohort comprised of Albertans from the Alberta Health Care Insurance Plan Registry (AHCIP) as of June 30, 2009 and aged 50 years or older. Those who received shingles vaccine were identified from the provincial...
In Canada, private purchase of human papilloma virus (HPV) vaccines has been possible since 2006. In Alberta, Canada, a publicly funded quadrivalent HPV vaccine program began in the 2008/2009 school year. There have been concerns about adverse events, including venous thromboembolism (VTE) associated with HPV vaccines. We describe the frequencies of adverse events following HPV vaccination among Alberta...
Children are key drivers of influenza transmission. Vaccinating school age children decreases influenza in the community.To pilot-test the methods for a future trial to compare the direct and indirect benefits of inactivated influenza vaccine (IIV) vs. live attenuated influenza vaccine (LAIV) in preventing influenza infection.During the 2013–14 influenza vaccination campaign, we piloted an open-label...
Streptococcus pneumoniae infections have periodically caused significant morbidity and outbreaks among military personnel, especially trainees. This study evaluated the effectiveness of the 23-valent polysaccharide pneumococcal vaccine (PPV23) in reducing pneumonia in healthy military trainees.From 2000–2003, 152723 military trainees from 5 US training camps were enrolled in a double-blind, placebo-controlled...
School-based influenza immunization can effectively address accessibility barriers, but injected inactivated influenza vaccines (IIV) may not be acceptable to some children and parents in school settings.To better understand the feasibility of offering intranasal live attenuated influenza vaccines (LAIV) through schools, we assessed uptake, stakeholder acceptability, and cost of school-based delivery...
Purpose: A universal publicly funded chickenpox vaccination program was implemented in Alberta in 2002. We examine the epidemiology of medically attended shingles in Alberta from 1994 to 2010.Methods: Incident shingles cases (earliest health service utilizations for ICD-9 053 or ICD-10-CA B02) and their co-morbid conditions for the 12 months prior to shingles diagnosis were identified from the records...
Adenovirus (ADV) types 4 (ADV-4) and 7 (ADV-7) are presently the major cause of febrile acute respiratory disease (ARD) in U.S. military recruits. We conducted a multi-center, randomized, double-blind, placebo-controlled phase 3 study of the new vaccine to assess its safety and efficacy. Healthy adults at two basic training sites were randomly assigned to receive either vaccine (two enteric-coated...
Influenza vaccine trials typically report vaccine efficacy for infection-confirmed symptomatic illness. Data on indirect vaccine efficacy for susceptibility, the degree of vaccine protection to susceptibles, or indirect vaccine efficacy for illness given infection, are sparse. Using inactivated influenza vaccine randomized trial data, we calculated indirect vaccine efficacy for susceptibility of 20%...
A systematic literature review identified 44 RCTs testing interventions to increase influenza vaccination rates among seniors ≥60. Case–control and cohort studies were excluded after review because of problems identifying secular trends and unknown confounders. Because of heterogeneity and unique interventions tested by a single or a few RCTs few studies could be pooled in meta-analysis. Using the...
The high burden of respiratory infections in military populations is well documented throughout history. The primary pathogen responsible for morbidity among US recruits in training was shown to be adenovirus. Highly efficacious oral vaccines were used for 25 years, but vaccine production ceased in 1996, and available stores were depleted by early 1999. Surveillance for acute febrile respiratory illness...
Effectiveness of the 2003–2004 influenza vaccine was evaluated at five military basic training centers throughout the United States. Data from surveillance conducted in December and January 2003–2004 in this highly vaccinated population were evaluated. During this period, 10.6% (37/350) of specimens were positive for influenza A. A 14-day period after vaccination was considered the period prior to...
Concerns have been raised about the beliefs and behaviours of chiropractors related to immunization; however, none have systematically examined the relationships between beliefs and behaviours.We examine the immunization-related behaviours and beliefs of chiropractors in Alberta, Canada, and explore the relationship of beliefs to immunization-related behaviours with patients.Data were collected in...
