Frequently asked questions

What is included in VS0 (Free)?
VS0 is VacStak's open-access general vaccine decision support storefront. It includes a basic vaccine ROI calculator, disease cost estimator, and herd immunity threshold tool — no login required. It's the entry point to the VacStak platform for any producer, vet, or researcher.
Does Enterprise really include AgrStak?
Yes — VacStak Enterprise gives you full access to AgrStak's 431+ agricultural calculators across 30+ storefronts, including crop production, soil health, carbon economics, grain science, and more. One login, two platforms, one Enterprise price. The same works in reverse — AgrStak Enterprise includes VacStak.
What is the epidemiology engine?
VacStak's epidemiology engine runs SIR and SEIR disease spread simulations, calculates herd immunity thresholds from real R₀ values, models outbreak probability under current vaccination coverage, and translates immunological targets into per-head financial decisions. It's available on Pro and Enterprise plans.
Can I cancel anytime?
Yes — all VacStak plans are month-to-month with no lock-in. You can upgrade, downgrade, or cancel at any time from your account dashboard. Your calculation history is preserved for 90 days after cancellation.
Is there a B2B or white-label option?
Yes — animal health companies, veterinary practices, and extension services can license VacStak calculators for embedding in their own platforms. Contact us at harry@vacstak.com to discuss custom pricing and API access.
When is VacStak launching?
VacStak is targeting a 2026 launch. VS0 is available now, with VS1–VS5 rolling out through 2025–2026. Sign up to be notified when your species storefront goes live.
