Ousseny Zerbo, PhD, is a Research Scientist in the Vaccine Study Center at Kaiser Permanente Northern California Division of Research. His research interest is in maternal vaccination during pregnancy and early childhood health outcomes, vaccine uptake, safety and effectiveness. He is the principal investigator on two NIH-funded projects to investigate the effectiveness of influenza vaccination, COVID-19 vaccination during pregnancy, and infant risk of influenza and COVID-19. He also studies risk factors associated with autism spectrum disorders.

Prior to joining the Vaccine Study Center, he completed post-doctoral training in the Autism Research Program at the Division of Research. He received his PhD in epidemiology from the University of California Davis and his bachelor's degree in biological science and teaching credential from the University of Ouagadougou, Burkina Faso, West Africa.

COVID-19 Vaccine Effectiveness in Pregnant Women and their Infants

The overall goals are to: Determine COVID-19 vaccine effectiveness in pregnant women for preventing laboratory-confirmed COVID-19 and hospitalization for COVID-19 using real-world clinical data; Determine effectiveness of maternal COVID-19 vaccination during pregnancy for infants 0-12 months for outcomes of laboratory-confirmed COVID-19, and hospitalization for COVID-19, and determine whether effectiveness varies by trimester of vaccination; Estimate COVID-19 vaccination rates among pregnant women and identify sociodemographic, geographic clusters and other factors associated with being unvaccinated.

Analysis to evaluate the effectiveness of a serogroup B outer membrane vesicle meningococcal vaccine against gonorrhea

The goal of this study is to use electronic medical records from 2016 to 2020 to evaluate the protective effect of MenB-4C vaccine against gonococcal infections among 16- to 23-year-old persons.
Investigator: Zerbo, Ousseny

Effect of Maternal Influenza Vaccination during Pregnancy on Risk of Infant Influenza

This project has three major aims: 1) to examine whether influenza vaccination during pregnancy prevents influenza and other respiratory infections in infants aged 0 to 12 months, with a sub-aim to examine the effect of vaccine timing during pregnancy on these outcomes; 2) to evaluate the effect of maternal influenza vaccination during pregnancy on the effectiveness of influenza vaccine administered to infants; and 3) to examine whether influenza non-vaccination during pregnancy clusters geographically, and determine if those clusters are associated with influenza and influenza-like illnesses during pregnancy.
