Barriers to immunization among newcomers: A systematic review.

Area of Science:

• Public Health
• Vaccinology
• Qualitative Research

Background:

• Limited evidence exists on factors influencing vaccine decision-making among newcomer populations.
• Understanding these factors is crucial for developing effective public health strategies.

Purpose of the Study:

• To systematically review qualitative studies identifying barriers to vaccination among newcomers.
• To inform targeted interventions for improving vaccine uptake in this demographic.

Main Methods:

• Systematic search of major biomedical databases (MEDLINE, EMBASE, CINAHL, Cochrane Central).
• Inclusion of qualitative studies examining newcomer attitudes, beliefs, and perceptions regarding vaccination.
• Content analysis methodology applied to identify and code barriers.

Main Results:

• Four primary barrier categories identified: cultural factors, knowledge deficits, insufficient healthcare access, and vaccine hesitancy.
• Most common barriers include lack of knowledge about vaccines/diseases and safety concerns.
• Specific barriers to Human Papillomavirus (HPV) vaccine uptake involve cultural beliefs about sexuality and incomplete understanding of HPV's role in cervical cancer.

Conclusions:

• Vaccination strategies for newcomers must address identified barriers.
• Tailoring interventions to the unique context and opportunities within newcomer populations is essential for success.
• Improving vaccine literacy and addressing cultural nuances are critical for enhancing vaccine acceptance.
