I just checked the website for covid vaccine requirements:
As of April 21, 2023, a single dose of Moderna COVID-19 Vaccine, Bivalent meets the vaccine requirement of these Technical Instructions for applicants 6 years old or older and a single dose of Pfizer-BioNTech COVID-19 Vaccine, Bivalent meets the requirements for applicants 5 years old or older. Although the monovalent Moderna and Pfizer-BioNTech COVID-19 vaccines are no longer authorized for use in the United States, these vaccines are still approved under these Technical Instructions because they are listed for emergency use by the World Health Organization and continue to require 2 or 3 doses (depending on age) to complete the requirement. Instructions for other vaccine formulations have not changed.
