Smallpox vaccination certificate.

How it's used
Refers specifically to the historical paper certificate issued after receiving a smallpox vaccine. It is now largely a term used by older generations or in historical contexts, as smallpox has been eradicated and routine vaccination stopped decades ago. The term carries a sense of nostalgia for a time when such documentation was a standard requirement for international travel.

to present the smallpox vaccination certificate
Common mistake
Do not confuse this with modern vaccination records, which are usually referred to as 疫苗接種記錄. Using 痘紙 for a current COVID-19 or flu vaccine certificate will sound very strange to native speakers.
