Vaccine data CER analysis
Students will analyze vaccine and antibody data and write a CER about immunity.
Written CER analyzing a vaccine antibody graph: claim about how vaccines build immunity, two specific data-point evidence entries, reasoning connecting memory B cells to protection, and one limitation.

- Claim, Evidence, Reasoning — make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure — the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.

💡 Big idea: Antibody-level graphs are the quantitative evidence that vaccines generate durable immune memory.
- 0-10Distribute and orient the vaccine antibody graph; label key features (peaks, doses, time axis)
- 10-25Guided annotation: mark primary response, secondary response, memory cell involvement
- 25-45Draft CER: claim about vaccine immunity, two data-point evidence entries, reasoning naming memory cells
- 45-58Add limitations section: at least one real limitation explained briefly
- 58-70Peer review: check that reasoning explicitly names memory cells and a mechanism
- 70-80Revise and submit CER
- • A vaccine trial produces exactly this kind of graph: antibody levels over time after one or two doses.
- • Today you will read that graph as a scientist and translate it into a CER.
- • Connecting the peak antibody level to memory-cell generation is the mechanistic reasoning that earns full marks.
- • You will also note a real limitation so your argument is scientifically honest.
- 1Examine a graph of antibody levels after vaccination.
- 2Make a claim about how vaccines build immunity.
- 3Cite two data points as evidence.
- 4Add reasoning connecting memory cells to protection.
- 5Note one limitation of the data.
- • CER includes claim, evidence, and reasoning.
- • Reasoning correctly explains immune memory.
- • A post-vaccination antibody graph typically shows a primary peak followed by a higher, faster secondary peak after a booster or re-exposure.
- • Memory B cells are the cellular basis of long-term vaccine protection.
- • Limitations of antibody data include waning immunity over time and individual variation in response.

Day 4 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete the vaccine or antibody data-analysis prompt in Lesson 3.2 Body Guards on myPLTW; finish it before peer review of your immunity CER.
Mark the analysis task complete in myPLTW after submitting your vaccine-data CER.
Modeling task is done; today the analysis task should show complete and your CER should be submitted.
