I would advise everyone to exhaust all other possible avenues before faking a vax card. Try for a religious exemption, try for a medical exemption, ignore your employer until they get in your face about the vax, and only then go the route of a vax card. Keep your paperwork and records. If they try to fire you over a fraudulent vax card, you can take them to court with documentation of your requested exceptions and prove that your employer was coercing you into a medical treatment against your will, and then you can explain how that unjust duress caused you to seek a fake vax card.
