What is a primary goal of vaccination?

The primary goal of vaccination is to establish herd immunity within the community. Herd immunity occurs when a significant portion of a population becomes immune to a disease, either through vaccination or previous infections. This immunity helps to protect those who cannot be vaccinated, such as individuals with certain medical conditions or allergies, by reducing the overall amount of the virus or bacteria that can spread within the community. By increasing vaccination rates, fewer individuals are available to transmit the disease, thereby lowering the chance of outbreaks and protecting vulnerable populations.

While other options may address various aspects related to vaccination, they do not align with the main public health objective. Generating profit for pharmaceutical companies or promoting specific brands of vaccines focuses on commercial interests rather than public health. Increasing hospital admissions is contrary to the purpose of vaccination, which is to prevent illness and reduce the need for medical interventions. Thus, the emphasis on establishing herd immunity highlights the collective benefit of vaccinations across a community.
