Examining Vaccine Effectiveness of Flublok Relative to Standard Dose Inactivated Influenza Vaccine Among Kaiser Permanente Northern California Members Aged 18-64 Years

This study employs a cluster randomization design to examine the vaccine effectiveness of Flublok relative to that of other flu vaccines used at Kaiser Permanente Northern California over two influenza seasons (2018 to 2019 and 2019 to 2020), in Kaiser Permanente Northern California members aged 18 to 64 years (comparator vaccines will not include high-dose or live vaccines). The primary age group of interest is 50- to 64-year-olds. Primary outcomes may include: 1) an influenza diagnosis confirmed by polymerase chain reaction (PCR) test as positive for influenza (A or B), 2) hospitalization with a PCR-confirmed influenza diagnosis regardless of the principal discharge diagnosis, and 3) hospitalization for pneumonia in December through March (regardless of whether there is a PCR test). Secondary outcomes may include other flu-related events, such as cardiovascular events (e.g., myocardial infarction or stroke) and other respiratory outcomes.

Shingrix Lead Site Evaluating the Effectiveness of Recombinant Zoster Vaccine

The purpose of this project is, first, to estimate the proportion of the population under study receiving one and two doses of recombinant zoster vaccine (RZV). Second, among live zoster vaccine (ZVL)-naive persons, this study aims to: 1) estimate the vaccine effectiveness of one dose of RZV, 2) estimate the vaccine effectiveness of two doses of RZV in 50- to 64-year-olds and those aged 65 and above, and 3) calculate the incremental vaccine effectiveness of a complete series (two-dose vaccine effectiveness versus one-dose vaccine effectiveness). Lastly, this study aims to estimate the vaccine effectiveness of one-dose RZV and of two-dose RZV among persons who previously received ZVL, as well as among immunocompromised persons.

A Continuation of Assessment of the Impact of Prevnar 13 on Invasive Pneumococcal Disease Caused by Vaccine Serotypes of Streptococcus pneumoniae After Introduction Into Routine Pediatric and Adult Use for the Period of May 2015 - April 2020

This project will estimate Prevnar 13 (PCV13) vaccine effectiveness against invasive pneumococcal disease using a test-negative design in the Kaiser Permanente Northern California adult population from September 1, 2014, through December 31, 2017. Positive cases will be defined as patients with invasive pneumococcal disease where serotype 3 is identified. Test-negative controls will be defined as patients with invasive pneumococcal disease where a non-PCV serotype is identified. As a sensitivity analysis, the vaccine effectiveness of Prevnar 13 against invasive pneumococcal disease caused by serotype 3 will also be compared with the vaccine effectiveness of 23-valent pneumococcal polysaccharide vaccine (PPV23) serotypes against invasive pneumococcal disease. In addition, invasive pneumococcal disease cases will be compared with the entire Kaiser Permanente Northern California adult population with similar characteristics matched on age, race, sex, and calendar time to better understand vaccination rates among different serotypes.

Continuation of Group B Streptococcus Epidemiology Study (Phase II)

Kaiser Permanente Northern California has recently collaborated with Pfizer in identifying invasive and noninvasive group B streptococcus (GBS) disease burden in adults during a seven-year time period spanning 2007 to 2014. In Phase 1 of this research collaboration, comorbid medical conditions in subjects with GBS disease were identified. In Phase 2 of this research collaboration, the burden of invasive and/or noninvasive GBS disease among subjects with the most commonly identified medical conditions identified in Phase 1 will be evaluated. These data will inform potential future study populations for the evaluation of a GBS vaccine in adults. The objective is to identify populations at highest risk for GBS disease (invasive and noninvasive) based on the pre-specified medical conditions and age groups from the Phase 1 analyses. Prediction models for patient risks of GBS will be developed, and with the models, each risk factor and combination of risk factors will be evaluated.

Identifying Target Populations for an Investigational C. difficile Vaccine

C. difficile-associated disease's (CDAD) clinical importance and its increasing incidence have resulted in C. difficile being a target for vaccine development. However, questions regarding which population may most benefit from receipt of a C. difficile vaccine remain. While CDAD is known to be associated with hospitalization, limited information exists regarding the burden of disease in specific populations such as those with underlying medical conditions. Further, the burden disease among those in long term care facilities and those in the outpatient setting is not well understood. The overall goal of this study is to identify potential at-risk groups which could be targeted to receive an investigational preventative C. difficile vaccine as part of a Phase 3 clinical trial.

Autoimmune disease risk following quadrivalent HPV vaccine/Prevention and Public Health Funds (PPHF)

Quadrivalent human papillomavirus vaccine (HPV4) is recommended for males and females 9-26 years of age. Pre-licensure trials for HPV4 did not find an imbalance of autoimmune diseases between study arms, however, associations between rare adverse events and the vaccine in these trials were difficult to detect due to limited sample sizes. Many autoimmune diseases manifest during the young adult years; it is important to assess if there is an increased risk of incident autoimmune disease following HPV4, which is recommended just before adolescence.
