Eligibility Criteria
You may qualify if:
- Patients who underwent solid organ transplantation prior to revaccination against COVID-19.
- Patients who have received the full COVID-19 vaccination regimen with Spikevax (Moderna) vaccine, with a minimum of 8 weeks having elapsed from the second dose to the time of trial initiation.
- Age \> 18 years.
- All participants must have previously agreed to participate in the study by signing the informed consent form.
You may not qualify if:
- Subjects without solid organ transplantation or with a different solid organ (e.g. pancreas transplantation) and without any type of immunosuppression (immunocompetent non-transplanted) from the general population.
- Age \< 18 years
- Temperature of at least 38°C in the 24 hours prior to immunization or other clinically relevant acute symptomatology.
- Clinical manifestations compatible with COVID-19 infection at the time of evaccination.
- Known allergy or history of anaphylaxis or other serious adverse events to the administration of vaccines or their excipients.
- Any other condition that contraindicates vaccination against SARSCov2, including pregnancy.
- Having presented graft rejection in the 15 days prior to the start of the study.
- Any condition or situation that may interfere with the ability to maintain adherence to study procedures and visits.
