Experimental: Cohort A: Individuals without cancer
A cohort of individuals without a cancer diagnosis is included for comparison. Because age is an important predictor of the ability to mount an effective immune response to vaccination, partners of patients in cohort B, C, and D.
|
Biological: mRNA-1273 SARS-CoV-2 vaccine from Moderna
All participants will receive two vaccinations against COVID-19 according to standard of care. |
Experimental: Cohort B: patients receiving immunotherapy
Cancer patients receiving immunotherapy
|
Biological: mRNA-1273 SARS-CoV-2 vaccine from Moderna
All participants will receive two vaccinations against COVID-19 according to standard of care. |
Experimental: Cohort C: patients receiving chemotherapy
Cancer patients receiving chemotherapy
|
Biological: mRNA-1273 SARS-CoV-2 vaccine from Moderna
All participants will receive two vaccinations against COVID-19 according to standard of care. |
Experimental: Cohort D: patients receiving chemo-immunotherapy
Cancer patients receiving chemo-immunotherapy
|
Biological: mRNA-1273 SARS-CoV-2 vaccine from Moderna
All participants will receive two vaccinations against COVID-19 according to standard of care. |
- Immune response to vaccination against COVID-19 measured as antibody response expressed as geometric mean concentration: arbitrary units (AU)/ml [ Time Frame: Measured at 28 days after vaccination ]The primary endpoint is the antibody based immune response to vaccination against COVID-19 on day 28 after the second vaccination in patients receiving cancer treatment as compared to individuals without cancer. Expressed as antibody response expressed as geometric mean concentration: arbitrary units (AU)/ml
- Safety assessment (S)AEs; Incidence and severity of solicited AEs during 7 days after each vaccination with incidence and nature of SAEs reported during 7 days after each vaccination [ Time Frame: During 7 days after vaccination ]
- Incidence and severity of solicited AEs during 7 days after each vaccination
- Incidence and nature of SAEs during 7 days after each vaccination
- Safety assessment immune related (ir), with incidence and nature of newly occurring irAEs grade ≥ 3 in cohort B and D reported up to 28 days [ Time Frame: From start till 28 days after second vaccination ]
- Incidence and nature of newly occurring irAEs grade ≥ 3 in cohort B and D up to 28 days after the last vaccination graded according to the Common Criteria for Adverse Events version 5.0 (CTCAE v5.0)
- Neutralizing capacity of antibodies to test functionality
- Assessment of SARS-CoV2 specific T cells response, 7 days, 28 days, and 6 months after vaccination using a high throughput Interferon ɣ ELIspot.
- Safety assessment AE of special interest (SI)s with Incidence, nature and severity of AESIs graded according to CTCAE v5.0 reported up to 12 months after vaccination [ Time Frame: From start till 12 months after vaccination ]- Incidence, nature and severity of AESIs graded according to CTCAE v5.0
- Assessment of immune response: expressed as geometric mean antibody concentration: arbitrary units (AU)/ml [ Time Frame: measured at 6 to 18 months after vaccination ]Persistence of antibody response expressed as geometric mean concentration: arbitrary units (AU)/ml
- Assessment of immune response: measured as levels of SARS-CoV-2 specific T-cell responses expressed as number of IFNg producing T cells/ million peripheral blood mononuclear cells (PBMCs) [ Time Frame: measured 28 days to 18 months after vaccination ]Levels of SARS-CoV-2 specific T-cell responses expressed as number of IFNg producing T cells/ million peripheral blood mononuclear cells (PBMCs)
