CDC/CVX Vaccine Codes

The page with the expanded list of vaccine codes here Valueset-vaccine-code - FHIR v4.6.0, says the list includes all codes defined in but that URL returns an error ‘Internal Error - unknown id cvx (from crsid.asp) .’

Is that last URL meant to be an API that you can query? What I’m looking for is a way to keep my application updated with the latest vaccine codes (URL or file a daily background job can consume).
