Polysaccharide vaccines are made from the sugar molecules that form the outer coating of some bacteria. These vaccines are effective in adults but are less effective in young children due to their immature immune systems.
Example: The Pneumococcal Polysaccharide Vaccine (PPSV23) protects against 23 types of pneumococcal bacteria.
Nursing Consideration: Nurses should note that polysaccharide vaccines may not provide long-term immunity and often require booster doses. They are usually administered to older adults and individuals with certain medical conditions.
