Clinical Trial of 23-valent Pneumococcal Polysaccharide Vaccine in Healthy Chinese Population Aged 2 Years and Above
Study Details
Study Description
Brief Summary
The group aged 18-59 years old, the group ≥60 years old, and the group aged 2-17 years old were successively assigned to the group. Subjects in each age group were randomly vaccinated with 1 dose of experimental vaccine or control vaccine in a ratio of 1:1, with 48 people in each group receiving each dose. After the safety assessment was conducted on the 8th day after the first dose, the next age group could be enrolled only if the preliminary safety assessment results met the protocol requirements. When each age group is enrolled, laboratory index screening can be conducted 3 days in advance (the validity period of laboratory index detection results is 3 days). The progression of age groups is as follows:
Group 18-59 years old (48 people: 1 dose) → Group ≥60 years old (48 people: 1 dose) → Group 2-17 years old (48 people: 1 dose)
Safety observation: All subjects were observed on site for 30 minutes after vaccination, abnormal laboratory indicators (blood biochemistry, blood routine) of all subjects were observed on day 4 after vaccination, and adverse events of all subjects within 0-7 days were actively followed up by the researchers, and subjects were instructed to record the body temperature measured every day and adverse events (if they occurred) in the diary card. All subjects continued to observe adverse events within 8-28 days and made relevant records. All subjects were required to continue follow-up for SAE status up to 6 months after basic immunization.
Immunogenicity observation: Blood samples were collected before and 28 days after vaccination, and serum antibodies were detected by ELISA.
