JI upholds rigorous editorial policies to protect research integrity and ensure reliable immunization scholarship. All submissions are evaluated for scope fit, ethical compliance, and reporting quality.

Policies align with international publishing standards and emphasize transparency in study design, data reporting, and conflict disclosure.

• Compliance with COPE and institutional ethics standards
• Informed consent and patient privacy protections
• Disclosure of conflicts of interest and funding sources
• Adherence to applicable regulatory requirements

Authorship should reflect substantive intellectual contributions to study design, data analysis, or manuscript preparation. All authors must approve the final version and agree to accountability for the work.

Contributor roles should be stated clearly to reflect individual responsibilities across the research workflow.

JI uses a single blind peer review model. Reviewers evaluate methodological rigor, diagnostic clarity, and public health relevance.

• Confidential reviewer identities
• Structured editorial oversight
• Clear revision guidance

• STROBE for observational studies
• CONSORT for randomized trials
• PRISMA for systematic reviews
• CARE for case reports
• TREND for non randomized evaluations
