Religious barriers to measles vaccination

Area of Science:

• Public Health
• Epidemiology
• Vaccinology

Background:

• Measles activity significantly increased in the United States in 2014, reaching levels not seen since the virus's elimination in 2000.
• Measles infections predominantly occur in unvaccinated populations.
• Vaccine refusal is often influenced by religious and philosophical objections.

Purpose of the Study:

• To examine the reasons behind vaccine refusal contributing to the resurgence of measles.
• To understand the specific objections cited by communities and individuals choosing not to vaccinate.

Main Methods:

• Analysis of reported measles cases and vaccination status.
• Review of documented reasons for vaccine refusal in the United States.
• Identification of primary religious and philosophical objections to vaccination.

Main Results:

• The 2014 measles increase was linked to unvaccinated individuals.
• Primary objections include religious concerns regarding aborted human fetal tissue in rubella vaccine components and animal-derived gelatin.
• Non-faith-based concerns about vaccine safety and efficacy also contribute to refusal.

Conclusions:

• Addressing vaccine hesitancy requires understanding and responding to specific religious and philosophical objections.
• Public health strategies must consider the diverse reasons for vaccine refusal to combat measles outbreaks effectively.
