Vaccination card in WA, U.S. for a person fully vaccinated abroad [duplicate]

My mother arrived today in WA, U.S. from Uzbekistan on an immigrant visa. She already had had 3 doses of Covid-19 vaccine (manufactured in China) in Uzbekistan before she got her U.S. visa. She had her Form I-693 completed (as a prerequisite for her immigrant visa interview at the U.S. Embassy). Also, she has foreign paperwork issued in Uzbekistan documenting her vaccination status. Here in King County, WA, many businesses require a person to present a CDC vaccination card to enter. How can she get a vaccination card or an equivalent acceptable in WA?
