Background: In 2016, the World Health Organization recommended that a fractional dose of yellow fever (YF) vaccine could be used in persons 2 years of age or older in response to an emergency that resulted in a global shortage of available YF vaccine. However, this recommendation did not extend to the youngest age group licensed for YF vaccine because there were no published data on the use or safety of fractional dose YF vaccination in children aged 9-23 months. We conducted a single-blind randomized controlled trial, comparing the immunogenicity and safety of fractional one-fifth and one-half doses of Bio-Manguinhos 17DD YF vaccine with full dose in children aged 9-23 months old in Uganda.

Prompted by unusual epidemiologic trends among reported non-NT cases, we conducted a retrospective record review to see whether these data reflected true disease burden.
Methods: We analysed nationally reported non-NT cases during 2012-2017.
The shift of middle-class jobs to home settings, which occurred as a result of COVID-19 health measures that also closed schools and daycares, introduced dynamic changes to everyday life. We investigate these changes drawing on data from our study in which participants in Nova Scotia, Canada, who were working at home due to the pandemic, wrote journal entries in response to weekly prompts. Participants not only documented changes to their routines and challenges of managing work and parenting simultaneously and in the same physical space, but also reflected on their conflicted emotions about life during the pandemic and their vision for life as things return to "normal.

However, the practices and strengths associated with solicited journal entries have not been explored as frequently or comprehensively as more conventional qualitative research methods, such as interviews. During the COVID-19 pandemic we carried out two online studies employing solicited written journal entries and photos.

Methods: We conducted a retrospective, incremental, ingredients-based cost evaluation from the provider perspective.
Following successful school-based demonstration programs in 2014-2016, the human papillomavirus (HPV) vaccine was introduced nationwide in Senegal for 9-year-old girls in 2018, using a routine service delivery strategy at health facilities, schools, and other outreach sites. We reviewed the HPV vaccine introduction in Senegal to understand the successes, challenges, and lessons learned. Focusing on three key domains (program decision-making, planning, and implementation), we conducted ten semi-structured interviews during 2019-2020 with purposively selected national-level stakeholders (government, expert advisory committee, key technical and implementation partners) and comprehensive desk reviews of country documents on HPV vaccine introduction.

The aims of this study are to analyze recent trends in national vaccination coverage in the World Health Organization African Region andto assess how these trends differ by country income category.
Methods: We compared national vaccination coverage estimates for DTP3 and the first dose of measles-containing vaccine (MCV) obtained from the World Health Organization (WHO)/United Nations Children's Fund (UNICEF) joint estimates of national immunization coverage for all African Region countries.
Objective: To profile chronic health conditions of an injured worker sample before and after workplace injury and compare injured workers to a matched community sample.
Methods: Logistic regression analyses compared risk of certain chronic health conditions for permanently disabled injured workers in the pre- and post-injury periods to comparator subsamples from the Canadian Community Health Surveys 2003 and 2009/2010.
Results: There were notable health differences between the injured worker and comparator samples for the post-injury period.
In 1974, the World Health Organization (WHO) established the Expanded Program on Immunization* to provide protection against six vaccine-preventable diseases through routine infant immunization (1). Based on 2015 WHO and United Nations Children's Fund (UNICEF) estimates, global coverage with the third dose of diphtheria-tetanus-pertussis vaccine (DTP3), the first dose of measles-containing vaccine (MCV1) and the third dose of polio vaccine (Pol3) has remained stable (84%-86%) since 2010. From 2014 to 2015, estimated global coverage with the second MCV dose (MCV2) increased from 39% to 43% by the end of the second year of life and from 58% to 61% when older age groups were included.

Background: The rate of unmet health care needs is quite high for the general population in Canada; however, the rate is even higher for the subset of people with disabilities. To date, there is a gap in the research utilizing longitudinal data to measure the unmet health care needs of Canadians.
Objective/hypothesis: The purpose of this research is to compare the rate of unmet health care needs of people with disabilities to people without disabilities over 15 years.
Purpose: To examine the construct validity and inter-rater reliability of the Neurological Impairment Scale (NIS) and compare ratings by medical and multidisciplinary teams in a mixed neurorehabilitation sample. To assess its concurrent and predictive validity as a predictor of outcome and functional gains during inpatient rehabilitation.
Methods: The NIS was rated in a consecutive cohort of patients (n = 428) recruited from nine specialist neurorehabilitation units in London.
Purpose: A phase III trial (Cancer and Leukemia Group B CALGB-49907) was conducted to test whether older patients with early-stage breast cancer would have equivalent relapse-free and overall survival with capecitabine compared with standard chemotherapy. The quality of life (QoL) substudy tested whether capecitabine treatment would be associated with a better QoL than standard chemotherapy.
Patients And Methods: QoL was assessed in 350 patients randomly assigned to either standard chemotherapy (cyclophosphamide, methotrexate, and fluorouracil [CMF] or doxorubicin and cyclophosphamide [AC]; n = 182) or capecitabine (n = 168).
