NCT04563273

Brief Summary

The study used a randomized, dose-escalation, blinded, placebo-controlled trial design. In this trial, 160 subjects were enrolled. The test vaccines are divided into four dose groups: dose group 1 (0.025mg / 0.1ml / person), dose group 2 (0.05mg / 0.1ml / person), dose group 3 (0.075mg / 0.1ml / person), dose group 4 (0.1mg / 0.1ml / person), each Each dose group was enrolled according to 18-45、 46-65 、6-10、11-17years old . The 4 doses are in descending order in the order of 18-45, 46-65, 11-17, and 6-10 years old. Each age group in the same dose group was enrolled in 8 experimental BCG subjects and 2 placebo subjects. Among subjects aged 6-65 years, the dose group 2 study will be carried out after the safety assessment 14 days after the dose group 1 vaccination, and the dose group 3 study will be carried out after completing the safety assessment 14 days after the dose group 2 vaccination. Dose group 3 studies were carried out after safety assessment 14 days after vaccination. Within the same dose group, after completing the safety assessment 14 days after vaccination for the previous age group, vaccination for the next age group is carried out.

Outcome Measures

Primary Outcomes (1)

  • Incidence of adverse events after vaccination

    Evaluate safety indicators before vaccination, 30 minutes, 7 days, and 14 days after vaccination. Collect all AEs 30 minutes after vaccination, 0-14 days of collected adverse events, 0-30 days of non-collected adverse events, within 6 months SAE, to evaluate the safety and tolerability of BCG vaccine for intradermal injection used in the test in people aged 6 to 65 years old with negative BCG-PPD and EC skin test

    Up to 6 months after the sixth time injection

Secondary Outcomes (2)

  • Positive conversion rate of BCG-PPD skin test 12 weeks and 6 months after vaccination

    Up to 6 months after the sixth time injection

  • Positive conversion rate of EC skin test 12 weeks and 6 months after vaccination

    Up to 6 months after the sixth time injection
