For providers · Vax

The immunization app inside your EHR

Schedules are more complex, doses are given in more places, and some vaccines can’t be billed in the office. Vax puts each patient’s open gaps in the chart and gives every one a next step before they leave.

  • Works with 11 EHRs today, with Epic in progress
  • Give it in the office, or book a nearby pharmacy and send the e‑prescription
  • Nothing to replace. Start with one clinic

We get your vaccine given

A recommendation becomes a dose only when someone sees the gap and can act on it. We work in every place that happens.

  • In the clinic: Vax, inside the EHR
  • At the pharmacy: appointments and e‑prescriptions sent from the visit
  • In schools: a year-round audit of every student’s record
  • In public health: clinic software, from one pop-up to mass vaccination

Every out-of-range result, followed to resolution

Panels keep expanding and follow-up runs longer. One record follows each baby from the first result to the final visit, alongside the lab system you already run.

  • Chosen by a leading state public health department
  • New conditions and workflows added by your own team, without IT support
  • AI-powered document scanning in place of manual data entry

Already running, every day

Why trust us

We were one of the teams in the field

We started in spring 2020 as volunteers running the data system behind community-wide testing in San Francisco’s Mission District and the coastal town of Bolinas. Today the platform is in daily use for immunization, testing, lab data, and case management, and it has carried statewide volume.

Our mission is to reduce the spread and severity of disease by making diagnostics, immunization, and preventive care simple and affordable to deliver at scale.
