What is the main consequence of an antivaccination campaign?

The main consequence of an antivaccination campaign is higher rates of disease outbreaks. When individuals opt out of vaccinations, it diminishes the overall immunity within a population, leading to a reduction in herd immunity. Herd immunity is crucial for protecting those who cannot be vaccinated, such as individuals with certain health conditions or allergies, as well as young children who may not have completed their immunization schedule.

As vaccination rates drop, preventable diseases can spread more easily, resulting in outbreaks. Historical examples, such as the resurgence of measles in areas with declining vaccination rates, underscore the relationship between vaccination coverage and disease prevalence. Thus, the prevalence of preventable diseases tends to increase significantly following antivaccination campaigns, posing serious public health risks.
