Trial overview
Official title:
Trial description: RZV was approved in 2017 by Food and Drug Administration (FDA) for the prevention of herpes zoster (HZ) in adults aged ≥50 years. RZV elicits a robust, antigen-specific humoral and cellular immune response in older adults and it could also induce trained innate immunity. Trained innate immune responses after exposure to selected vaccines may trigger non-specific protection against infectious diseases, potentially including COVID-19. The aim of this study is to investigate the potential for RZV to induce trained innate immunity that may translate into some protection against severe COVID-19.

- Cohort Study:
- Individuals aged ≥50 years as of 01/03/2020
- Cohort Study:
- Individuals with COVID-19 outcomes that occur ≤14 days after receipt of RZV will be excluded. This will only affect individuals who received RZV close to the beginning of the study period (01/03/2020).
Inclusion and exclusion criteria
Inclusion criteria:
- Individuals aged ≥50 years as of 01/03/2020
- At least 1 year of continuous KPSC membership prior to 01/03/2020 (allowing for a 31-day gap) Test-Negative Design:
- Individuals aged ≥50 years as of date of SARS-CoV-2 test
- At least 1 year of continuous KPSC membership prior to date of SARS-CoV-2 test (allowing for a 31-day gap)
- Tested for SARS-CoV-2 from 01/03/2020 to 31/12/2020
Cohort Study:
Exclusion criteria:
- Individuals with COVID-19 outcomes that occur ≤14 days after receipt of RZV will be excluded. This will only affect individuals who received RZV close to the beginning of the study period (01/03/2020). Test-Negative Design:
- Individuals who receive a first dose of RZV within 14 days prior to the SARS-CoV-2 test will be excluded, to ensure that individuals were not infected with SARS-CoV-2 prior to vaccination.
