How to Order:
Prevar 20 is a pneumococcal conjugate vaccine that is designed to protect against 20 different strains of the bacteria Streptococcus pneumoniae. This vaccine contains a combination of 20 different capsular polysaccharides from the pneumococcal bacteria, which are conjugated to the diphtheria toxoid protein CRM197. This allows the immune system to recognize and respond to the polysaccharides and provide protection against the bacteria. Prevar 20 is commonly used to prevent pneumonia, meningitis, and other invasive pneumococcal diseases in adults and children.
Prevar 20 is a pneumococcal conjugate vaccine that protects against infections caused by the 20 most common serotypes of Streptococcus pneumoniae bacteria. The vaccine is made by combining 20 different polysaccharides (a type of carbohydrate found on the surface of the bacteria) with the Diphtheria CRM197 protein. This protein helps to make the polysaccharides more recognizable to the body's immune system, allowing it to produce a stronger and longer-lasting immune response.
When a person is vaccinated with Prevar 20, their immune system recognizes the polysaccharides as foreign and starts producing antibodies to fight them off. These antibodies are specific to each of the 20 serotypes included in the vaccine. If the person is exposed to any of these serotypes in the future, their body will be prepared to quickly fight off the infection before it can cause illness.
Prevar 20 is also designed to provide herd immunity, which means that even individuals who are not vaccinated can be protected if a large enough portion of the population is vaccinated. This is because the spread of disease is limited when a significant number of people are immune.
Overall, Prevar 20 works by stimulating the body's defense mechanisms to protect against 20 different strains of Streptococcus pneumoniae bacteria, helping to prevent severe and potentially life-threatening infections.
