E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
An observational study in healthy, differently PFAS-exposed subjects to check if PFAS modifies the immunological response to SARS-CoV-2 vaccination. The immunological response is quantified as SARS-CoV-2-specific IgG antibody production and T-cell activity. |
En observationsstudie i friska, olikt PFAS-exponerade personer för att se om PFAS modifierar den immunologiska response till SARS-CoV-2 vaccination. Den immunologiska response är kvantifierad som SARS-CoV-2-specifik IgG-antikroppsproduktion och T-cellsaktivitet. |

E.1.1.1 | Medical condition in easily understood language |
An observational study in healthy subjects with different exposure to Perfluoroalkyl substances (PFAS). The aim is to see if PFAS affects immune response after SARS-CoV-2 vaccination. |
En observationsstudie i friska deltagare med olika exponeringar för Perfluorerade Alkylsubstanser (PFAS). Syftet är att se om PFAS påverkar immunsvaret efter SARS-CoV-2-vaccination. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The overarching aim is to gather knowledge about how Perfluoroalkyl substances (PFAS) affects the immune system. This aim is studied through immunological response after SARS-CoV-2-vaccination in adults.
Primary research question: Does PFAS-exposure modify IgG-antibody production after SARS-CoV-2-vaccination?
The question will be answered through quantification of IgG-antibodies against SARS-CoV-2 S-protein. Exposure to PFAS is quantified as the molar sum of the 16 PFAS-substances in serum, and stratified into low and high. |
Det övergripande syftet är att få ökad kunskap om hur PFAS påverkar immunsystemet. Specifikt studeras det immunologiska svaret vid vaccination mot SARS-CoV-2 bland vuxna.
Primär frågeställning: Påverkar PFAS-exponering IgG-antikroppssvaret efter vaccination mot SARS-CoV-2?
Utfallsmått: IgG mot SARS-CoV-2 S protein. Exponeringsmått: Summan av 16 PFAS-ämnen i serum, kategoriserad som antingen låg eller hög.
|
|
E.2.2 | Secondary objectives of the trial |
Secondary research question: Does PFAS-exposure affects the cellular immune response after SARS-CoV-2-vaccination?
This question will be answered through analyses of SARS-CoV-2 specific T-cell response. Exposure to PFAS is quantified as the molar sum of the 16 PFAS-substances in serum, and stratified into low and high.
|
Sekundär frågeställning: Påverkar PFAS-exponering det cellulära immunsvaret mot SARS-CoV-2 S protein efter vaccination mot SARS-CoV-2?
Utfallsmått: För T-celler bestäms SARS-CoV-2 specifika T-cellssvar. Exponeringsmått: Summan av 16 PFAS-ämnen i serum, kategoriserad som antingen låg eller hög. |
|
