🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionNot applicable. This medicine is administered by injection and does not undergo absorption from the gastrointestinal tract.
DistributionNot established from the available information.
Protein BindingNot established from the available information.
MetabolismNot applicable. This medicine is a vaccine and is not metabolized like conventional drugs.
Half-LifeNot established from the available information.
ExcretionNot established from the available information.
BioavailabilityNot applicable. This medicine is given by injection, so bioavailability is 100% relative to the injected dose.
Onset of ActionThe immune response begins within days but protective antibody levels typically develop over 2 to 4 weeks after vaccination.
Peak Plasma TimeNot established from the available information.
Duration of ActionProtection may last for several years, but the exact duration varies by serotype and individual immune response.

How It Works

This medicine works by inducing an immune response against the polysaccharide capsule of Streptococcus pneumoniae. The polysaccharide antigens are conjugated to a carrier protein, which enhances the immune response by promoting T-cell dependent B-cell activation. This leads to the production of antibodies that bind to the pneumococcal capsule, marking the bacteria for destruction by phagocytes and complement-mediated lysis. The vaccine contains multiple serotypes, providing broad protection against the most common disease-causing strains.

Mechanism Steps

1
Antigen recognition: The conjugated polysaccharide antigens are recognized by antigen-presenting cells.
2
T-cell activation: The carrier protein stimulates T-helper cells, which then activate B-cells.
3
Antibody production: Activated B-cells produce specific antibodies against the pneumococcal polysaccharides.
4
Immune memory: Memory B-cells are formed, providing long-term protection against future exposure.
