Antibody testing is not currently recommended check someone’s immunity

[GoodTaste]

Should I get an antibody test after the vaccine to make sure it’s working?
Antibody testing is not currently recommended check someone’s immunity to COVID-19 following either the Pfizer-BioNTech or Moderna vaccines. The COVID-19 antibody test used at MSK detects the immune response after being infected by COVID-19. It does not measure immunity that results from the vaccine. That’s why it should not be routinely ordered to assess vaccine response.

The word "check" appears to be a verb. If so, is "to" (to check) necessary there? Is the phrase "Antibody testing is not currently recommended check someone’s immunity" grammatical?

I agree with you - the "to" is missing.

As a noun you'd need to say something like as a check of- it's a typo.
