How to Apply for Senior Vaccination Researcher
at GiveWell
🏢 About GiveWell
GiveWell is a nonprofit that uses rigorous evidence and cost-effectiveness analysis to find the most impactful giving opportunities in global health and development. Unlike many organizations, they are transparent about their reasoning and openly share their research, making them a unique and trusted voice in effective altruism. Working here means your research directly influences where millions of charitable dollars are allocated, potentially saving or improving thousands of lives.
About This Role
As a Senior Vaccination Researcher, you will lead GiveWell's efforts to identify and fund the most cost-effective vaccination programs globally. You will own the entire grantmaking process—from setting research agendas to evaluating evidence and modeling cost-effectiveness—and your recommendations will direct millions of dollars to high-impact interventions. This role combines deep analytical work with real-world decision-making, offering the chance to shape global health policy and mentor the next generation of researchers.
💡 A Day in the Life
A typical day might start with reviewing new trial data on a vaccine candidate and updating a cost-effectiveness model to reflect the latest evidence. You might then meet with a junior researcher to discuss their progress on a grant investigation, followed by a call with a partner organization to clarify implementation details. After lunch, you could draft a recommendation memo for an upcoming grant decision, balancing quantitative outputs with qualitative judgment on feasibility and equity.
🚀 Application Tools
🎯 Who GiveWell Is Looking For
- Expert in evidence review and cost-effectiveness modeling, with a track record of using quantitative analysis to inform funding decisions in global health.
- Deep knowledge of vaccination research, including familiarity with vaccine efficacy, delivery logistics, and epidemiological data in low-resource settings.
- Strong judgment and ability to synthesize complex, often conflicting evidence to make clear, well-reasoned recommendations under uncertainty.
- Proven mentoring and communication skills, able to guide junior researchers and present findings persuasively to both internal teams and external partners like funders and policymakers.
📝 Tips for Applying to GiveWell
Tailor your resume and cover letter to highlight specific experience with cost-effectiveness models (e.g., DALYs averted per dollar) and evidence review (e.g., systematic reviews, meta-analyses) in global health or vaccination.
Showcase your ability to make judgment calls under uncertainty—mention a time you had to weigh conflicting data or incomplete evidence to reach a funding recommendation.
Demonstrate familiarity with GiveWell's research methodology by referencing their published reports or cost-effectiveness analyses (e.g., their work on malaria chemoprevention or deworming).
Emphasize any experience with vaccination programs in low- and middle-income countries, especially if you've worked with partners like Gavi, WHO, or ministries of health.
Include examples of mentoring or leading research teams, as the role involves developing junior researchers and fostering a collaborative environment.
✉️ What to Emphasize in Your Cover Letter
["Your alignment with GiveWell's mission to find and fund the most cost-effective giving opportunities, and your passion for using evidence to maximize impact per dollar.", 'Specific examples of your expertise in cost-effectiveness modeling and evidence review, ideally applied to vaccination or global health interventions.', 'Your ability to take ownership of complex research projects from start to finish, including setting priorities, conducting analyses, and making actionable recommendations.', 'Your experience communicating technical findings to diverse audiences, including non-experts, funders, and policymakers, and your commitment to transparency.']
Generate Cover Letter →🔍 Research Before Applying
To stand out, make sure you've researched:
- → Read GiveWell's recent vaccination-related grant recommendations (e.g., on measles campaigns or HPV vaccination) to understand their decision-making framework.
- → Study their cost-effectiveness model templates and how they estimate the impact of interventions (e.g., lives saved, DALYs averted).
- → Review their 'Our Criteria' page to understand how they define cost-effectiveness and what evidence standards they require.
- → Familiarize yourself with key debates in global health vaccination (e.g., the role of Gavi, vaccine hesitancy, or new vaccine introductions) to show informed perspective.
💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
- Overemphasizing personal passion for vaccines without demonstrating rigorous analytical skills—GiveWell values evidence over advocacy.
- Being vague about your experience with cost-effectiveness modeling; provide concrete examples and metrics (e.g., 'I built a model that compared 10 interventions and identified a program with $50 per DALY averted').
- Ignoring the mentoring aspect of the role—failing to mention how you've developed others or collaborated on research can signal a lack of fit for a senior position.
