Vaccination Programs and Herd Immunity is a part of the VCE Biology area of study ‘How do Cells Communicate?’ and subtopic ‘Immunity’. Vaccination programs are determined by governing bodies to ensure that communities are protected against easily transmittable diseases. Herd immunity is when a large portion of the community has immunity against a disease, which then prevents spread of the disease to non-immune people. This prevents catastrophic outbreaks.
How do Vaccines Help with Herd Immunity?
Watch this video to learn about the relationship between a widely vaccinated community and herd immunity.
