Defence and vaccination against infection

Before covid-19
 People still questioned the validity of vaccines
 Marked increase in cases of measles – there were 991 in 2018 – due to the increase
in people not having the vaccine
Who should be vaccinated?
 Risk of suffering with severe diseases
 People who may infect others
 People exposed to the disease
 Age
 Health status
 Vaccine history
 Special risk factors
 Reactions
 Cost
From immunity to vaccination
 Inducing immunity by triggering the immune response
 T-cells good at discriminating the different epitopes
 The high specificity of T-Cells is something which comes at a cost – takes a long time
for immunity to kick in
 Clonal selection and expansion
 Essential feature
 If the antigen fits the right match for the receptor the cell expands and duplicates –
leads to effector cells which makes antibodies and memory cells which are a
secondary response for if you encounter the same antigen
 Primary response after vaccination leads to faster immune response after a natural
infection
Types of vaccines
 Active – induces a state of immunological readiness – produces an immune response
 Passive – don’t ask them to develop the immune response you give them the
effectors to give enhanced immunity
 Can both be protective and limit the infection and disease
Benefits of vaccination
 Protection of the person – protects from severe disease – need to understand the
pathology of the disease and what the disease effects and how the immune
response must be
 Protection of the population – epidemiology, mode of transmission must be
understood
 Passive vaccination
o Transfer specific antibodies
o Tetanus
o Rabies
o Snakebite
o Hepatitis B
 Normal serum gammaglobulins – top up antibodies
 Maternal antibodies – mothers to babies
