Examining the Relationship between Race, Ethnicity, and Sociodemographic Factors and Coverage of Three Vaccines: COVID-19, MMR, and HPV
The incidence of vaccine-preventable diseases is on the rise in the United States and globally. This is due to multiple factors including a recent surge in vaccine hesitancy, which the WHO has named a top ten global health threat, and persistent barriers to accessing vaccination. These factors have …

Assessing the Sensitivity of the Canadian Adverse Event Following Immunization Surveillance System ( CAEFISS)
<p><strong>Background</strong>: Vaccines are important to public health, but because of the way they are manufactured, their mechanism of action, and their indicated population, careful monitoring of their adverse events is necessary. Canada has a national surveillance system that collects reports …

Monitoring immune dynamics following infection and vaccination using B cell receptor sequencing
… Vaccination against measles virus with the MMR vaccine has been a major factor in reducing direct and secondary childhood morbidity and mortality. The maintenance of sufficient global vaccine coverage, however, has been challenging due to the refusal of vaccination, mainly in religious …

Towards Rheumatic Heart Disease vaccine development: Defining host immune responses to Group A Streptococcal infection in Cape Town
Group A streptococcus (GAS) vaccines, as a primary prevention strategy, have the potential to prevent the spread of the bacteria, thus limiting post-sequelae diseases such as acute rheumatic fever (ARF) and rheumatic heart disease (RHD). Due to the limited supply of penicillin, adherence issues and …
