[MCOH-EH] [EXTERNAL] COVID Vaccination Dose #2 in employees who become positive after dose #1

We are administering dose 2 when they clear isolation. The rationale is bifold:

·         There is zero data on the effectiveness of a series separated by 90+ days. The phase 3 trials had no participants with doses that far apart.

·         Dose #2 has been allocated to you for the person who received dose 1. If you give that dose 2 to someone else as their dose 1, you will not get dose 2 shipped to you for the second person! Delaying dose 2 is not really opening up a dose 1 appointment so you don’t get the altruistic benefit of increasing access to others. Unless you want to start giving access to a partial series.

What are your policies for the following:

Employee has first vaccine and then becomes positive for COVID before the second dose. We have decided, based on the CDC site, COVID before or after 1st dose and before 2nd, don't need to interrupt the schedule, reschedule as long as symptoms resolved and at least 10 days from symptom onset or positive test in an asymptomatic employee.

I have talked with other institutions and some are postponing the second dose for 90 days from symptom onset or positive test in an asymptomatic positive. This they have said is to use the vaccine for others.

Anyone else doing anything different?
