## Idea

Vaccine eligibility reminder card
Helps family caregivers check vaccine eligibility and receive reminders when official guidance changes.

## Product concept

Users enter a family member’s age range, underlying conditions, previous vaccination history, and state. The page generates a checklist covering whether they can get vaccinated now, what to ask a doctor, and where to schedule an appointment. It sends alerts only when CDC or FDA guidance changes. The focus is not to make a decision for a doctor, but to organize eligibility rules, risk notes, and vaccine options scattered across official websites into a checklist for a visit.

## Why now (backed by facts)

CDC information continues to change, and the FDA has approved a new Novavax indication, so ordinary people need to recheck age, risk, and available vaccination options. These changes make caregivers repeatedly search official websites and pharmacy pages.

## Direction (model inference, not independently verified)

Target user: Everyday US family caregivers arranging vaccinations for parents, partners, or family members with chronic conditions

Minimal entry point: Start with a single-page app covering only COVID-19 vaccine eligibility under CDC and FDA guidance. Users do not register; they complete a form to receive a local result and an alert link. Exclude inventory checks, appointment payments, medical-record uploads, and medical advice. Put the original source beside every conclusion.

The strongest case against: The strongest case against this is that willingness to pay for eligibility checks is questionable. The evidence looks more like an information need among consumers confused by policy changes, not proof that they will leave CDC, pharmacy, or doctor channels to buy an independent tool. If medical information is wrong, the trust and liability costs are also high.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Create indexable question-and-answer pages for “Novavax indication,” “COVID-19 vaccine eligibility,” and “Can someone with a chronic condition get vaccinated?” Place a free eligibility checklist in caregiver forums, chronic disease communities, and pages commonly searched before pharmacy appointments. The product’s sharing point is sending it to a family member or doctor for confirmation.

## Competitors & gaps (model inference)

- CDC: CDC must maintain a public information function. It generally does not save an individual family’s status or proactively alert them after updates across visits.
- Vaccines.gov: Vaccines.gov is mainly an entry point for finding vaccination locations. It does not explain how eligibility changes combine with a user’s personal risk conditions.
- CVS Pharmacy: A pharmacy appointment page supports its own fulfillment process. Its structure is not suited to neutral explanations of eligibility across multiple vaccines with side-by-side official source references.

## How it makes money (model inference)

Caregivers pay to save the eligibility card as a family record, receive alerts when official guidance changes, or export it for physician review; chronic disease communities and clinics may also pay for branded patient information pages.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
