Objective: This review synthesizes qualitative research about the experiences of parental caregivers enhancing their children's health after making the decision to not vaccinate their preschool children. This review aims to help health care providers understand the parental work involved in caring for under-vaccinated or unvaccinated children.

Introduction: Much of the current qualitative research literature about parents who are vaccine-hesitant or who decide not to vaccinate their children focuses on parental perceptions about the safety and efficacy of vaccines and decision-making.

Epigenetic therapies facilitate transcription of immunogenic repetitive elements that cull cancer cells through 'viral mimicry' responses. Paradoxically, cancer-initiating events also facilitate transcription of repetitive elements. Contributions of repetitive element transcription towards cancer initiation, and the mechanisms by which cancer cells evade lethal viral mimicry responses during tumor initiation remain poorly understood.

We aimed to understand how experiences with vaccine-related information and communication challenges during the COVID-19 pandemic impacted motivations and behaviors among Canadian adults regarding future vaccines. Semi-structured interviews were conducted with participants purposively selected to ensure diversity in age, sex at birth, self-identified gender, and region. Data were analyzed using thematic analysis; findings were mapped to the Information-Motivation-Behavioral Skills Model focusing on factors affecting vaccine hesitancy and uptake.

Work in many systems has shown large-scale changes in gene expression during aging. However, many studies employ just two, arbitrarily-chosen timepoints at which to measure expression, and can only observe an increase or a decrease in expression between "young" and "old" animals, failing to capture any dynamic, non-linear changes that occur throughout the aging process. We used RNA sequencing to measure expression in male head tissue at 15 timepoints through the lifespan of an inbred strain.
