On January 20, the Central Epidemic Command Center (CECC) announced that in response to the threat posed by the Omicron variant, starting January 21, 2022, people visiting some leisure and entertainment venues including singing and dance venues, discos, nightclubs, clubs, hostess bars, pubs, beauty parlors (tourist parlors and audio-video parlors), hostess teahouses, and saunas should show their record of receiving two doses of a COVID-19 vaccine 14 days ago before they enter such a venue. Such a record of vaccination can be a paper vaccination card, Digital COVID-19 Certificate, or digital record shown on the NHI Express App for verification.

For hospitals, residential long-term care facilities, and other venues that have required a COVID-19 vaccination record before entry, a record of vaccination required to enter those venues can also be a paper vaccination card, Digital COVID-19 Certificate, or digital record shown on the NHI Express App for verification.
