Mechanism of action

Vaccines stimulate the immune system to recognize and fight specific pathogens. They achieve this by introducing antigens, which are substances that provoke an immune response, including the production of antibodies. The immune system creates a memory of these antigens, allowing for a quicker and more effective response upon subsequent exposure to the actual pathogen.

Pharmacodynamics

The pharmacodynamics of immunization involves the activation of both the humoral and cellular immune responses. This leads to the production of specific antibodies and the differentiation of memory B and T cells, which provide long-lasting immunity. The timing and type of immune response can vary depending on the vaccine type, the route of administration, and the individual's previous exposure to the pathogen.

Pharmacokinetics

The pharmacokinetics of vaccines can vary widely based on their formulation. Generally, vaccines are administered via intramuscular or subcutaneous injection, where they are absorbed into the bloodstream. The onset of immunity can occur within days to weeks, depending on the vaccine and the individual's immune response. The duration of immunity may vary, necessitating booster doses for certain vaccines to maintain protection.

Mechanism of action

Live vaccines work by introducing a weakened or attenuated form of a pathogen into the body. This stimulates the immune system to recognize and respond to the pathogen, leading to the production of antibodies and memory cells that provide long-term protection against future infections by the same pathogen.

Pharmacodynamics

The pharmacodynamics of live vaccines involve the activation of both humoral and cellular immunity. Following vaccination, the immune system generates a robust response, including the production of specific antibodies and the activation of T cells that can recognize and eliminate infected cells. This dual action helps establish long-term immunity.

Pharmacokinetics

The pharmacokinetics of live vaccines vary depending on the specific vaccine. Generally, the vaccine is administered via injection, allowing the live attenuated organisms to enter the bloodstream. The immune response typically begins within days and can last for years, depending on the vaccine. Live vaccines are usually stored under refrigeration to maintain their viability, and they should be administered within their expiration dates.

Dosage

Children: Dosage varies by vaccine type and age; refer to the BNF for Children for specific dosing information.

Adults: Dosage varies by vaccine type and indication; refer to specific guidelines for each vaccine.

Mechanism of action

Vaccines work by mimicking an infection. They introduce a harmless component of a pathogen (antigen) to the immune system, prompting the body to produce an immune response. This includes the generation of antibodies and memory cells that provide long-term immunity. Upon subsequent exposure to the actual pathogen, the immune system is primed to respond more rapidly and effectively.

Pharmacodynamics

The pharmacodynamics of vaccines involves the activation of both humoral and cellular immunity. Vaccines stimulate B cells to produce antibodies against the pathogen, while T cells are activated to destroy infected cells. This dual response helps to establish immunological memory, which enables a faster and more robust response upon re-exposure to the pathogen.

Pharmacokinetics

Vaccines are administered via various routes, including intramuscular, subcutaneous, and oral. After administration, the antigens are presented to antigen-presenting cells, which activate T cells and stimulate B cell proliferation and differentiation. The half-life of vaccine-induced immunity varies depending on the type of vaccine, with some providing lifelong immunity and others requiring booster doses to maintain protection.

Contra-indications
