BC COVID-19 Vaccine Passport

BC's COVID-19 vaccine passport is encoded as a JSON web token following the SMART Health Card open spec.

I made a little write up about how to decode the data.

Vax codes

You can inspect the http://snomed.info/sct coding key to see which type of vaccines were recorded:

• 28581000087106 – PFIZER-BIONTECH COVID-19 messenger ribonucleic acid 30 micrograms per 0.3 milliliter suspension for dilution for injection Pfizer Canada ULC-BioNTech Manufacturing GmbH (real clinical drug)
