Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The accomplishment of this study will allow to evaluate the safety and effectiveness of the primary vaccination against yellow fever in patients with rheumatologic diseases. It is generally expected that the vaccine will be safe for this group of patients, but with a lower vaccine response associated with disease activity and greater inflammatory response. The primary endpoint will be to assess the seroconversion rate through the PRNT technique 28 days after receiving the vaccine (17DD YF -Instituto Biomanguinhos-FIOCRUZ) | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoint will be to evaluate possible adverse events related to the administration of the 17DD YF-Instituto Biomanguinhos-FIOCRUZ vaccine. | — |
