IMMUNIZATION
Immunization is vital for preventing infectious diseases by stimulating the immune system to produce an immune response against specific pathogens. It's one of the most effective public health interventions, preventing millions of deaths each year.Several types of immunization
Live attenuated vaccines: These contain weakened forms of the virus or bacteria that stimulate an immune response without causing illness. Examples include the measles, mumps, and rubella (MMR) vaccine.
Inactivated vaccines: These contain killed versions of the virus or bacteria. Examples include the polio vaccine and the hepatitis A vaccine.
Subunit, recombinant, polysaccharide, and conjugate vaccines: These contain only specific parts of the virus or bacteria, such as proteins, sugars, or capsid components. Examples include the hepatitis B vaccine and the HPV vaccine.
Toxoid vaccines: These contain inactivated toxins produced by the bacteria. Examples include the tetanus and diphtheria vaccines.
mRNA vaccines: These are a new type of vaccine that use mRNA to instruct cells to produce a protein similar to a protein found in the virus, triggering an immune response. Examples include the Pfizer-BioNTech and Moderna COVID-19 vaccines.
Each type of vaccine has its own advantages and considerations, and they are used depending on factors such as the target disease and individual health status.
