Thanks to Nathan Hammond you can monitor COVID-19 Vaccine locations open up in Hong Kong. He released a monitoring tool as a GitHub gist. I set it up on my Mac. Had to use

brew install watch

To install the watch command line tool. I also customized the to point to the correct path of the cvc.js file. Then I got the list of vaccine centers in json and customized the to include the ids of my nearest vaccine centers.

Finally I also customized the cvc.js file to filter by a later date. For me it is 2021-04-01 because I was trying to find a jab sooner.

Thanks Nathan for releasing the script.
