Up until around November 17 of 2021, the vaccination status of foreign residents in Taiwan wasn’t listed on their NHI app or in their card details. Some information was clearly available, given that so many foreign residents were able to get vaccinations and follow-up vaccinations on the online appointment platform, but what do you do if the information shown on your card is in conflict with the info displayed online or on the NHI app?

UPDATE (March 10, 2022): If you got your vaccinations before you updated your NHI card to match your new ARC number format, the vaccination record on your online records and in the NHI app won’t be carried over and you’ll also have to go through the process detailed below.

This happened to me, in that the Heping Branch of Taipei City Hospitals still haven’t uploaded info from my first vaccine in May, meaning that my second vaccination is listed as my first:

As the qualifying criteria for a booster dose is 5 months passing since your second dose, I thought I’d given the hospital a reasonable enough window in which to update the details if they were going to. So I called the 1922 hotline, and they told me to go to my local district health and welfare office (區衛生所), these are called district health and care centers (區健康照顧中心) or district health service centers (區健康服務中心) in Taipei City. The one for Zhongzheng District is here.

Take your yellow vaccination card and your NHI card to your local branch, and they’ll take your details at reception and ask you to fill out a form.

Essentially, the helpful lady at the counter told me that they will contact the hospital to request that they update their records and then they’ll contact me when it’s done.

UPDATE:
The records were updated the following day:

It’s probably best to update your online status, so that when it comes time for your booster, the system will know when you become eligible (5 months after your second dose).
