Clinical Trial Summary

The research objective is to evaluate lot-to-lot consistency and immune persistence of three commercial batches of 23 valent pneumococcal polysaccharide vaccine.

Description:

This study adopted a randomized, double-blind, equivalency design with different batches of experimental vaccine. 990 individuals aged 18-59 were included and divided into three groups at a ratio of 1:1:1, with 330 individuals in each group receiving three batches of experimental vaccines, respectively. All subjects were vaccinated with 1 dose of 0.5ml, intramuscularly injected into the lateral deltoid muscle of the upper arm.

Eligibility

Inclusion Criteria:

• Healthy volunteers aged 18-59;
• Voluntarily participate and sign an informed consent form;
• Subjects are able to comply with the requirements of the clinical study protocol and complete the prescribed follow-up;

• Subjects with a history of thrombocytopenia or other coagulation disorders that may cause contraindications for subcutaneous injection;
• Subjects with known immunological dysfunction or low levels, or HIV infection;
• Any situation leading to splenomegaly, splenectomy, or functional splenomegaly;
• Malignant tumors, active or treated tumors that have not been clearly cured, or are likely to recur during the study period;
• Anti tuberculosis prevention or treatment is under way;

• Women of childbearing age are in pregnancy (positive urine pregnancy test) or lactation period;
• Any situation that the researcher believes may affect the evaluation of the study.
