A total of 14 patients will be enrolled to assess the safety of TA-CIN vaccine via different injection sites as adjuvant therapy. Safety assessments will continue for a period for 1 month after the last vaccination. Few or no serious adverse events (SAEs) are expected from this regimen and routes of administration. The motivation for the design is to confirm that the dose and site of injection implemented here has minimal or no systemic toxicity, as well as determining the preferred injection site that can elicit more potent immune response.
