This highlights another problem with the vaccination program and use of vaccination for anything other than it's public health value. There is a general assumption that all people vaccinated are same and all vaccines are equivalent. The Novavax is not even available in USA outside clinical trials. There are other such vaccines which have been administered to hundreds of millions of vaccinated people worldwide. All these vaccines have varying levels of effectiveness. Even in USA currently there are three vaccines and it is unlikely they are equivalent.

To use vaccination as a substitute for testing in international travel will require a definition of what vaccination means. There would probably then have to be 1) an approved list of vaccines and/or 2) another test that proves that the vaccination actually resulted in immunity in that person (such as a vaccine specific antibody test). As the CDC reported this week few thousands of the millions vaccinated people are still suffering from COVID, so being vaccinated certainly doesn't eliminate the risk to the degree one can assume all vaccinated people are covid negative. It is also not yet established whether or not, and also how easily, a vaccinated person can transmit COVID-19.
