Vaccination card for scale.
If you choose to go this route, remember these will probably be printed on card stock, rather than printer paper. It would be best to obtain first-hand recon when these are released as to actual color, size and "feel" -thickness.
Before filling one out, research your area as to who is providing the vacs, the address of the actual vacs location (physical stick), rather than just the associated hospital/clinic, as there may be a temporary location used for mass vacs. Also, review who (actual Doc/Nurse/PA) is giving the vacs.
If you know someone who takes the vacs, try to get a look at their card for reference.
Communication is the key to success.
