Hi Maria,
This is a common misconception that postvaccination antibodies are helpful, but actually they are not. For measles, mumps, rubella or varicella, development of a positive IgG after vaccination
does not always indicate full protection, and conversely a negative post-vaccination IgG is not an indication of non-response. If you happen to draw one on someone who has good documentation of completed vaccination, and it returns negative, you ignore it.
Unlike hepatitis B, with MMRV there is no indication to provide additional doses until someone “converts” and you don’t label them a “nonresponder.” In the event of an exposure, consider everyone with good documentation of being appropriately vaccinated to
have evidence of immunity. (Note that if there is an ongoing community or facility outbreak, especially of mumps, public health authorities might recommend a 3rd MMR for everyone with 2 prior doses.)
See attached ACIP recommendations – drawing your attention to page 13 for this comment on measles:
“For HCP who have 2 documented doses of MMR vaccine or other acceptable evidence of immunity to measles, serologic testing for immunity is not recommended. In the event that a HCP who has 2 documented doses of
MMR vaccine is tested serologically and determined to have negative or equivocal measles titer results, it is not recommended that the person receive an additional dose of MMR vaccine. Such persons should be considered to have presumptive evidence of measles
immunity. Documented age-appropriate vaccination supersedes the results of subsequent serologic testing.”
You will see the same guidance for mumps, rubella, and varicella on pages 16, 19 and 24, respectively.
For a more eloquent explanation of this, I highly recommend a recent OccPod (Episode 56) interviewing Dr. Amy Behrman!

Hope this helps,
Melanie

Just curious… how do you know which employees mounted an immune response and which didn’t – since no vaccine is 100% effective.
Would you consider an employee, whose titer you didn’t know, immune in the event of an outbreak?
How would you know who to quarantine and who not?
Thanks,
Maria

We don’t draw titers for MMR/VZV and Hep B automatically. If someone comes in with the Hep B series already completed the Hep B titer is offered, but not required. The MMR/VZV titers aren’t drawn in employee health anymore. We used to,
but it wasn’t cost effective, and CDC says it’s not necessary. Back when we were doing all the titers automatically, we did the QFT/IGRA because as you said its much more convenient, but it was very expensive for the clinic to cover.

Am curious… whenever I see people still using the TST I’m curious….
You’re drawing blood for MMR/VZV, Hep B, so why doesn’t your facility use QFT/IGRA for such an important test? It’s much more convenient, expeditious and accurate, as you know.
Is it because your volume is low? The hospital is undoubtedly already doing or contracted to do IGRAs for patients: can you make everyone’s life easier by using them in OHS?
Wondering!

Thank you all so much for the suggestions. We do have a policy in place for PPDs and employee health, but at the time of their hire we didn’t. When I spoke with them, they wouldn’t give me an answer as to their hesitation with either the
PPD or the blood draw. I did end up getting their manager involved and explained if we weren’t able to figure it out amongst us that I would have to get HR involved. Thankfully, they agreed to doing the PPD. I’m not sure why the hesitation, especially since
they’ve had them in the past. I will follow up with HR and make sure in our hiring process that applicants are aware of this requirement.

We have ours written into our pre-employement screening policy and a screening test is a condition of employment. If they refuse the onboarding process would stop.
Since you are finding it upon review, may be a challenge to enforce. However it is an opportunity to review policy and process and make sure everything is clear. A surveyor is going to look for the follow up action. What did you put in place to prevent reoccurrence
as much as how you dealt with the delinquent finding.
Let us know how it turns out.

If you have an institution policy that will back your request for the PPD or Quantiferon then that is what you use to support the request. A policy which outlines mandatory PPD or Quantiferon will allow
you to push the issue and take it to the employee’s Manager to enforce that they are compliant. If you get no where with management then you can step it up to the HR level to enforce compliance. However without an institutional policy that mandates employees
having a PPD or Quantiferon makes it tough to push the issue.

How do you handle an employee who is refusing to do a PPD or Quantiferon-gold? This employee was a rehire in 2015, when this employee was initially hired in the 90’s they had PPDs done, several actually,
as they were still checking them annually. When this employee was rehired in 2015, they declined to redo the PPD. I’ve been working on getting all our employee health files completed, and I came across the incomplete screening in their fire (they filled out
the questionnaire, but nothing was administered), reached out to them and they’re declining both a PPD or Quantiferon-gold.
Any suggestions, resources, recommendations, etc. would be much appreciated.
