2. Receipt of the mRNA COVID-19 vaccine booster prior to date of licensure/authorization (i.e., September 11, 2023 for XBB formulation)
3. Receipt of the licensed/authorized mRNA COVID-19 vaccine prior to being eligible

a. Exclude patients who received the licensed/authorized vaccine <2 months since receipt of the most recent prior dose
4. Exclude patients who have had >1 mRNA COVID-19 vaccine dose of the current formulation prior to COVID-19 diagnosis
5. Exclude patients who had a non-Pfizer/BioNTech COVID-19 Vaccine of the current formulation prior to COVID-19 diagnosis

Summary
Brief summary
This study aims to use vaccination information from state vaccine registries linked with HealthVerity insurance claims for the following:

* to measure how effective the Pfizer-BioNTech vaccine is at preventing post-COVID conditions.
* to understand characteristics of patients who are receiving COVID-19 vaccines.

All patients whose information is kept unidentified in the HealthVerity database are eligible to be included for both aims of this study.
