VTL travelers from the US to Singapore can use the digital vaccination record instead of the smart health card: CAAS.
Five more states, namely Arizona, Maryland, Mississippi, North Dakota and West Virginia, are “in the process of doing so,” as is the District of Columbia.
Connecticut, Massachusetts and Oklahoma have begun testing the system, Ms. Tan said.
In addition to the states, pharmacies and healthcare providers such as CVS Health, Rite Aid Pharmacy, UCHealth, and Walmart are also issuing SHCs.
Some external issuers do not administer the vaccine but do provide their users with a digital vaccination record, often for a fee.
Ms. Tan said CAAS is bringing in outside issuers who check and verify vaccination records submitted by their users, for example with state immunization records.
“We cannot accept digital certificates issued by third-party issuers that do not perform such controls,” he added.
“With the deployment of the SHC in more states and the addition of credible third-party issuers, we expect that the majority of US travelers will be able to produce a digitally verifiable vaccination certificate within the next one to two months.”
Travelers are advised to consult the Safe Travel Website for updates on the list of accepted digital vaccination certificates. Travelers who need more help can write to the Insurance Travel Office through their Consultation Form or call the Safe Travel Inquiries helpline at +65 6812 5555.
