E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Does antibody development to SARS-CoV-2 S protein differ after vaccination between those who have had a previous SARS-CoV-2 infection compared to Covid-19 naive individuals? |
Skiljer sig antikroppsutveckling mot SARS-CoV-2 S-protein efter vaccination mellan de som haft tidigare SARS-CoV-2-infektion jämfört med Covid-19 naiva individer? |
|
E.2.2 | Secondary objectives of the trial |
Better understanding of how the human immune system reacts when exposed to foreign protein antigen measured as antibody level in serum, plasma and mucosa as well as at the cellular and genetic level. The secondary issues are those that are general to understanding how the human immune system works in both infection and vaccination. |
Att bättre förstå hur det mänskliga immunförsvaret reagerar när det blir exponerat för främmande proteinantigen mätt som antikroppsnivå i serum, plasma och slemhinna samt på cellullär och genetisk nivå. De sekundära frågeställningarna är sådana som är generella för att förstå hur det mänskliga immunförsvaret fungerar vid både infektion och vaccination.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Consents to participate in the study • Age ≥ 18 years |
• Samtycker till deltagande i studien • Ålder≥ 18 år
|
|
E.4 | Principal exclusion criteria |
• Age <18 years • Incapable of giving informed consent (does not apply to participants in the elderly study) • Contraindication to vaccination • Severe disease (assessed to affect the subjects ability to complete the study) • Ongoing treatment that is judged to affect the vaccine response (Does not include inhaled steroids and nasal sprays, as well as tablet cortisone ≤15mg / day. Rituximab treatment is not an exclusion criterion.) Participants in the elderly study: The exclusion criteria described in the protocol above for CoVacc will not apply to the sub-study called The Elderly Study, this clinical research study in which people with severe illness and people who lack their own decision-making ability can be included. Data on chronic diseases or drugs will not be collected
|
• Ålder <18 år • Beslutsoförmögna personer (gäller ej deltagare i äldrestudien) • Kontraindikation till vaccination • Svår sjukdom (som bedöms påverka forskningspersonens möjlighet att fullfölja studien) • Pågående läkemedelsbehandling som bedömes påverka vaccinsvaret (innefattar inte inhalationssteroider och nässpray, samt tablett kortison ≤15mg/dag. Rituximab behandling är ej ett exklusionskriterie) Deltagare i äldrestudien: De exklusionskriterier som är beskrivna i protokollet ovan för CoVacc kommer inte att gälla den delstudie som benämns Äldrestudien, denna kliniska forskningsstudie där personer med svår sjukdom och personer som saknar egen beslutsförmåga kan inkluderas. Uppgifter om kroniska sjukdomar eller läkemedel kommer inte att insamlas.
