Coverage averaged across a county can hide the pockets that sustain transmission. At Week 8 in PHLT 8072, the program appraisal example weighs a composite two-dose measles program on that basis.

What a finished PHLT 8072 Week 8 program appraisal looks like
The appraisal runs about four pages under five headings: program description, transmission target, coverage evidence, heterogeneity and verdict. Program description sets out the composite program's parts, routine two-dose vaccination through clinics, a school-entry requirement with exemptions, and catch-up clinics after outbreaks. The transmission target section states what the program must achieve in terms of the herd immunity threshold, explained as a concept with no value attached. Coverage evidence appears in a small table of invented figures by school, a high county average beside several schools far below it. The heterogeneity section argues that measles finds those schools, because contacts concentrate within them. The verdict rates the program as sound in design and uneven in reach, then names two changes aimed at the pockets: school-level coverage reporting and catch-up offered where exemptions cluster.
How a PHLT 8072 Week 8 example is structured
Target is stated before evidence, so coverage figures are always read against what they are meant to reach. The SIR model is named plainly in that section, susceptible, infectious and recovered, for the idea that vaccination moves people straight out of the susceptible compartment, and the herd immunity threshold is introduced as the share of immunity at which each case produces fewer than one more on average. Anderson and May are credited for the argument that uneven mixing changes that picture: when immunity and contact both cluster, a population average can clear the threshold while subgroups fall well short. That credit organizes the heterogeneity section. The school table sits between the model and the verdict, letting the argument meet invented numbers before any judgment. The verdict separates design from reach, since each calls for a different fix.
Three program parts
Routine two-dose vaccination, a school-entry requirement with exemptions and outbreak catch-up clinics are described in turn.
A threshold stated as a concept
The share of immunity needed to halt sustained spread is defined through the SIR model, with no value quoted.
Averages and pockets
A table of invented school figures sets a high county mean beside several schools far below it.
Why clustering defeats the mean
Contacts concentrate within schools, so susceptible children meet one another more often than the average implies.
Design sound, reach uneven
The verdict separates the two and names school-level reporting and targeted catch-up as responses to the pockets.
Where marks go in PHLT 8072 Week 8
Credit follows the gap between average and pocket. Appraisals that report county coverage and declare success have evaluated the program's paperwork, not its effect on transmission, and this appraisal leaves the average behind within a paragraph. Framing the threshold as a concept, without quoting a value, earns accuracy credit and avoids the commonest numerical slip. The Anderson and May paragraph draws the heaviest share, because it explains why clustered immunity defeats an adequate average. The school table earns its place by applying the argument to data, with every figure marked invented. Separating design from reach in the verdict collects the synthesis marks. Proposed changes earn a smaller share when each targets the pockets directly. Appraisals weaken by treating exemptions as the only cause, by ignoring infants too young to be immunized, or by proposing changes unlinked to transmission.

PHLT 8072 Week 8 questions, answered
What is the herd immunity threshold?
The proportion of a population that must be immune for each infection to produce, on average, fewer than one new infection, so that transmission declines. It rises with the agent's basic reproduction number, which is why measles demands a high threshold. The appraisal explains the concept and quotes no value. A custom appraisal can include a published estimate if your prompt requires one, cited to its source.
Why name the SIR model in a program appraisal?
It gives the simplest account of what vaccination does: moving people from susceptible to immune without passing through infection. That picture explains why coverage matters at all, and its limits, uniform mixing above all, explain why averages mislead. The appraisal uses the model in words, not equations. If your course expects a worked example, a custom sample adds one with invented, labeled inputs.
Are the school coverage figures real?
They were made up for the page and carry a label saying so. They exist to show how a sound county average can sit above schools with far lower coverage, which is the appraisal's point. No actual district, school or program is described. A custom appraisal working from your state's published school coverage reports would cite them directly, reporting year included.
