Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Adverse Events of Special Interests (AESIs)

    Index date (that is, first day of health plan eligibility within the applicable time period where all study entry criteria are met) through end of data availability or earliest event (maximum of 751 days depending on duration of capture in the database)

Study Arms (4)

Cohort 1a: Pre-COVID

All participants meeting eligibility criteria in the Pre-COVID-19 period (immediately preceding the emergence of COVID-19) (Time Period 1) from 01 December 2018 to 30 November 2019

Cohort 1b: Pre-COVID

All participants with evidence of an influenza vaccination and meeting eligibility criteria in the Pre-COVID-19 period (immediately preceding the emergence of COVID-19) (Time Period 1) from 01 December 2018 to 30 November 2019

Cohort 2: Active-COVID

All participants meeting eligibility criteria in the Active-COVID-19 period, Pre-Emergency Use Authorization (EUA) period (following the emergence of COVID-19 but before the first COVID-19 vaccine EUA) (Time Period 2) from 01 December 2019 to 10 December 2020 (1 day prior to first United States SARS-CoV-2 vaccine EUA)

Cohort 3: Post-EUA

All mRNA-1273 vaccinated participants meeting eligibility criteria in the Post-EUA period (Time Period 3) from date of first United States SARS-CoV-2 vaccine EUA to 31 December 2022

Study Population

The study population will be selected from HealthVerity's aggregated medical and pharmacy claims database that represents healthcare utilization for over 140 million participants between 01 December 2017 and the end of the study period (31 December 2022).

You may qualify if:

  • Included in a health plan covered by HealthVerity database
  • Covered by a health plan during at least 1 period of interest (pre-COVID-19, active-COVID-19, and post-EUA periods), but not necessarily the full period.
  • Demonstrate an AESI specified clean period of continuous baseline enrollment or activity before the period of interest (pre-COVID-19, active-COVID-19, and post-EUA periods) during which the participant is covered.

You may not qualify if:

  • None
