The PVC (Pneumococcal Conjugate Vaccine) is made by combining polysaccharides from the capsule of Streptococcus pneumoniae bacteria with a carrier protein. The polysaccharides are purified and then conjugated to the protein, enhancing the immune response. This process stimulates the body to produce antibodies against the bacteria, providing protection against pneumococcal diseases. The vaccine undergoes rigorous testing for safety and efficacy before being approved for public use.
