Pneumovax II

University of Oxford · Phase 3 active Biologic ✓ Verified May 2026

Pneumovax II is a vaccine Biologic drug developed by University of Oxford. It is currently in Phase 3 development for Prevention of invasive pneumococcal disease caused by Streptococcus pneumoniae in adults 50 years of age and older.

Pneumovax II stimulates the immune system to produce antibodies against Streptococcus pneumoniae.

Pneumovax II is a protein-based vaccine that targets Streptococcus Pneumoniae. It is used to prevent infections caused by Streptococcus Pneumoniae, as indicated by its study in ClinicalTrials.gov for conditions such as Infections and Streptococcal infections.

Likelihood of approval
59.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr
TGA AU 2029–2032 +1.2 yr
PMDA JP 2029–2032 +1.5 yr
NMPA CN 2030–2033 +2.3 yr

CDSCO IN 2029–2033 +1.8 yr
ANVISA BR 2030–2033 +2.3 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design. Per-jurisdiction lags from Tufts CSDD international approval studies. Not investment, clinical or regulatory advice. Methodology: /methodology#likelihood.

Mechanism of action

This is achieved through the administration of inactivated pneumococcal polysaccharides, which are recognized by the immune system as foreign and trigger an immune response. This response leads to the production of antibodies that can recognize and bind to the polysaccharide capsule of S. pneumoniae, thereby preventing the bacteria from causing disease.
