didn't get the memo...(see link)...and apparently you didn't either....find another false trope to peddle.
As for COVID vaccines and immigrants...go to the CDC website...ALL immigrants are required to have been vaccinated in their home countries (if available) before entry, or submit to a health screening where if they are age-eligible, and not qualified for a waiver, they WILL be vaccinated...
Once again, you fail to do your homework and make an erroneous post based on what you "Think" is correct....not a good strategy.
