• Rubella
• Yellow fever
• Varicella (chickenpox)
• Rotavirus

Dosage

Children: Refer to specific vaccine guidelines for paediatric dosing.

Adults: Refer to specific vaccine guidelines for adult dosing.

Mechanism of action

Attenuated vaccines work by mimicking a natural infection. The weakened pathogen replicates in the body, stimulating the immune system to produce a response against it, which includes the activation of T-cells and the production of antibodies. This prepares the immune system to recognize and fight off the pathogen if exposed in the future.

Pharmacodynamics

The pharmacodynamics of attenuated vaccines involve the interaction of the attenuated pathogen with the host's immune system. Upon administration, the vaccine induces both humoral (antibody-mediated) and cell-mediated immunity. This leads to the development of memory cells that ensure a faster and more effective response upon subsequent exposure to the actual pathogen.

Pharmacokinetics

Attenuated vaccines are generally administered via subcutaneous or intramuscular injection. The pharmacokinetics are characterized by the distribution of the vaccine components within the body, with the attenuated organisms replicating locally and inducing an immune response. The onset of immunity typically occurs within weeks, and the duration of immunity can vary depending on the specific vaccine.
