Step-by-step explanation:
The approach described by the CDC (Centers for Disease Control and Prevention) in recommending that everyone 6 years and older should receive an updated Pfizer-BioNTech or Moderna COVID-19 vaccine, regardless of their previous vaccination status, reflects a **"universal vaccination"** or **"population-based"** approach to public health.
In a universal vaccination approach, the goal is to provide vaccination to an entire population or a large segment of it, without considering individual risk factors or prior vaccination history. This approach is often used when dealing with infectious diseases like COVID-19, where achieving widespread immunity is crucial in preventing the spread of the virus and reducing the impact of the disease on the population.
The idea behind this recommendation is to maximize vaccination coverage to create a strong barrier of immunity within the community, which can help control the spread of the virus, protect vulnerable individuals, and reduce the overall burden of severe illness, hospitalization, and death. It simplifies the vaccination process by making it accessible to a broader population and reduces the need for complex eligibility criteria.
This universal vaccination approach is often employed in the context of a public health crisis to achieve widespread immunity quickly and effectively.
