Dated edits to this page's evidence: studies added or removed from a claim, claims added or withdrawn, and new explanations tagged here. Rewordings are not listed.
- Concept page published
Vaccination research here covers uptake, coverage, and interventions that change who gets immunized — not only vaccine biology.
Public-health students need evidence on hesitancy, access, and programme design as much as immunology.
Evidence
What the evidence shows
Drawn from 10 studies in this library. Each finding starts with a plain-language takeaway, then the denser detail. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope with a short note on each study’s contribution. Challenged positions are labeled — they are not findings.
Multiple studies in this library examine vaccination with empirical patient or population outcomes rather than opinion alone.

Seasonal coverage was about 20.6–20.8% overall and about 55% among at-risk people. Pandemic coverage was 11.1% overall; older adults had high seasonal but low pandemic uptake.
Among 15,087 respondents, acceptance was 79.6% for ≥90% efficacy, 60.6% for ≥70%, and 41.2% for 50%. Most respondents were general public; about one-quarter were students or clinicians.
Overall, 79.8% were somewhat or very likely to vaccinate when available and recommended. Respondents skewed female, white, and highly educated, mean age about 52.
Overall VE ~48% against incident zoster; 62% against PHN at 30 days and 59% at 90 days; uptake was only 3.9% and lower in Black and low-income groups.
Open questions
Tensions and limits
Some items are genuine disagreements on the same question. Others mark different assays, populations, or outcomes — limits on how far one study travels — not a forced fight between papers.
Effect sizes and settings differ across vaccination studies — digital vs clinic, trial vs observational — so results should not be pooled casually.

Common misconceptions
Vaccination findings always generalise to every clinic.
These studies are context-bound; designs, populations, and endpoints limit transfer.
Exam-style questions
Short-answer questions that ask you to explain or compare, not recall.
What is Vaccination and why do health students study it?
Vaccination research here covers uptake, coverage, and interventions that change who gets immunized — not only vaccine biology. Public-health students need evidence on hesitancy, access, and programme design as much as immunology.
Name one limit of the evidence base for Vaccination in this library.
Single-setting trials, observational designs, or digital-only samples limit causal and external claims.
The studies
10 studies in this library bear on Vaccination, ordered by citations. The first 8 are shown.
- What predicts COVID-19 vaccine willingness
About two-thirds of surveyed adults were ready to vaccinate; perceived risk, news sources, and partisanship shaped willingness.
- Parents and school HPV uptake
In BC’s free school HPV program, about 65% of surveyed parents reported first-dose receipt—lower than concurrent hepatitis B and meningitis C consent rates.
- Shingles vaccine cut zoster by about half
In older US adults, herpes zoster vaccination showed ~48% effectiveness against incident zoster and ~59–62% against post-herpetic neuralgia.
- COVID vaccine acceptance in Libya
Willingness to take a COVID-19 vaccine rose with assumed efficacy—about 80% if efficacy was ≥90%, but only about 41% if 50%.
- As chickenpox shots rose, what happened to shingles?
In Massachusetts, higher childhood varicella vaccine coverage tracked with less varicella but more reported herpes zoster—causality still uncertain.
- TPB best predicted COVID vaccine hesitancy
Among Bangladeshi adults, COVID-19 vaccine hesitancy was common (41.1%), and the Theory of Planned Behavior explained more variance than HBM or 5C models.
- Who decides about adolescent vaccines—and what blocks uptake?
Adolescents, parents, and clinicians shared overlapping and conflicting views on adolescent vaccination barriers and how to improve decisions.
- COVID-19 vaccine intention in BC
About 80% of surveyed British Columbians said they were somewhat or very likely to take a recommended COVID-19 vaccine.

- Seasonal vs pandemic flu vaccine coverage
In France, seasonal influenza coverage stayed near 21% while pandemic H1N1 coverage was only about 11%.
- What predicts full childhood immunization in Senegal
Only 62.8% of Senegalese children 12–23 months were fully immunized; maternal education, wealth, and antenatal care strongly predicted coverage.
