What is a conjugated vaccine?

in medicine is a conjugated vaccine or a conjugated vaccine, a type of vaccine that is created by combining the antigen to the protein molecule. Conjugated vaccines are usually used to immunize children and children against certain bacterial infections. Mature immune systems of very young people often have difficulty recognizing certain antigens, so that common vaccines may not be effective for some diseases. The protein part of the conjugated vaccine acts as an antigen carrier and is used to increase the immunological response to it. In this way, conjugated vaccine can be significantly more successful in immunizing children and children against certain bacteria. In these bacteria, a layer of mucus constructed from molecules of polysaccharides protects antigens on the surface of the bacterial cell. This makes it difficult for immune cells or white blood cells to recognize bacteria and attach an immunological attack. Therefore, the conjugated vaccine usually consists of a polysaccharide antigen combined with a support protein. A combination of antigen with protein creates a substance toIt is easier to recognize for white blood cells in human blood, leading to a stronger immune response.

Two important vaccines in the care of children's health are pneumococcal conjugated vaccine (PCV) and meningococcal conjugated vaccine (MCV). PCV is commonly used in many countries to prevent bacterial meningitis, pneumonia and related infections in children. This vaccine does not protect immunized children from all pneumococcal bacteria. There are more than 90 different types of pneumococcal bacteria and pneumococcal conjugated vaccine protects only from seven of them. These seven types of bacteria, However, cause a large part of severe pneumococcal diseases and the vaccine can prevent the vast majority of these infections.

Meningococcal conjugated vaccine is designed to protect children from a different meningitis tribe caused by a bacterium called meningococcus. It works similar to PCV and is used for immunuCandting young children and adolescents up to 18 years. This vaccine is usually given to children and young adults who have experienced exposure to meningococcal bacteria, for example, if the incidence of meningitis at school or university has occurred.
