Subject: Prospective PhD student: Co-Creation Dear Professor Grewal, My name is [your name], and I am a [your current degree or role] at [your institution]. I am applying for a PhD position starting in [term and year]. I read your paper "Human papillomavirus (HPV) vaccine coverage and associated sociodemographic factors among individuals eligible for publicly funded vaccine in Ontario, Canada from 2007 to 2023: A Canadian immunization research network study." (2026), and it connects closely to my own work on [your research topic]. [One or two sentences on what you did and what you learned.] I also saw your CIHR-funded project "Developing a community-based research agenda to address unmet needs in the context of Human Papillomavirus (HPV)" (2024), and I would be glad to contribute to work in that direction. Are you accepting new PhD students for [term and year]? I have attached my CV and transcripts, and I would be glad to talk at a time that suits you. Thank you for your time.
