Triple-boosted... or double-boosted and confused.

 

Hm. I just got Shot #5, but Apple Wallet can't handle all 5 doses... only the last 4.
Dose #1 06Feb2021
Dose #2 27Feb2021
Dose #3 16Aug2021
Dose #4 21Jan2022
Dose #5 22May2022

Another weirdness: There are now two files in Apple Health Immunizations, instead of just one. The first one contains Doses 1-4, and the other contains Dose 5. (You'd expect the second one to contain Doses 2-5, in order to produce the Apple Wallet Vaccination Card mentioned above.) Also, when you read the latest CDC guidelines, they keep moving the goalposts: a primary series is now 3 doses, making dose 4 into booster 1, and dose 5 into booster 2. Nota Bene: "You can self-attest to your moderately or severely immunocompromised status. This means that you do not need any documentation of your status in order to receive COVID-19 vaccine doses wherever they are offered."

Pfizer-BioNTech schedule for the immunocompromised:
2nd dose given 3 weeks (21 days) after 1st dose.
3rd dose given at least 4 weeks (28 days) after 2nd dose.
4th dose (1st booster) given at least 3 months after 3rd dose.
5th dose (2nd booster) given at least 4 months after 1st booster.
So the 5th dose could theoretically be given less than 9 months after 1st dose.
What in holy h*ll took me so long? 😉

PS: Shot #4 was Pfizer purple.
Shot #5 was Pfizer gray.
I just hope they didn't dilute it...
