Study start date: April 30, 2025

Actual date on which the first participant was enrolled.

The design of a randomized, randomized (test and placebo) triple-blind (patient, investigator and evaluator) clinical trial is proposed. The clinical trial will be carried out in accordance with the criteria recommended in the CONSORT Guidelines. All patients who agree to participate will have a sample taken following the manufacturer's instructions for the design of the autovaccine, using a sterile swab that will be placed in transport medium (AMIES type) and sent to the laboratory. After 1 month of taking the sample, the laboratory that will be in possession of the randomization will damage the container/dispenser, which will be exactly the same in both groups T and P. Group T will be administered the complete autovaccine, while group P , the content will be the same except for the active ingredient, that is, only thimerosal, methylcellulose, sodium chloride and orange essence. In this way, neither the research group nor the patient himself will be known by the group to which he has been assigned. In the event of unforeseen adverse effects, which are not expected, patients will be withdrawn from the study and treated according to standard care practice. All patients will be able to resort to rescue medication if the symptomatology is exacerbated during the follow-up period of the study, always under the prescription of the physician (nystatin aqueous rinse solution 1ml/100,000 IU or oral Fluconazole 50 mg/24 hours).
