Overview of Vaccines
Gordon Ada
1. Patterns of Infectious Processes
Most vaccines are designed as a prophylactic measure to stimulate a lasting immune
response so that on subsequent exposure to the particular infectious agent, the extent
of infection is reduced to such an extent that disease does not occur (1). There is also
increasing interest in designing vaccines that may be effective as a therapeutic measure, immunotherapy.
There are two contrasting types of infectious processes.
1.1. Intracellular vs Extracellular Patterns
Some organisms, including all viruses and some bacteria, are obligate intracellular
infectious agents, as they only replicate inside a susceptible cell. Some parasites, such
as plasmodia, have intracellular phases as part of their life cycle. In contrast, many
bacteria and parasites replicate extracellularly. The immune responses required to control the different patterns of infections may therefore differ.
1.2. Acute vs Persistent Infections
In the case of an acute infection, exposure of a naive individual to a sublethal dose
of the infectious agent may cause disease, but the immune response generated will
clear the infection within a period of days or weeks. Death occurs if the infecting dose
is so high that the immune response is qualitatively or quantitatively insufficient to
prevent continuing replication of the agent so that the host is overwhelmed. In contrast, many infections persist for months or years if the process of infection by the
agent results in the evasion or subversion of what would normally be an effective
immune control reaction(s).
Most of the vaccines registered for use in developed countries, and discussed briefly
in the next section, are designed to prevent acute human infections.
