Vaccinations: part 1
When no vaccinations are being given against a disease,
the number of people catching it is high.
People's attention is focused on the disease and its effects.
When an immunisation programme against a disease begins,
the number of people catching it goes down.
Some people experience side-effects from the vaccine,
though these are usually mild.
As more and more people get immunised,
the threat of the disease becomes much less.
People stop worrying about the disease
and start thinking about possible side-effects of the vaccine.
People can start to question the necessity and safety of vaccines
and fewer get immunised.
As fewer people are being immunised, the disease starts to spread again.
People are reminded of how bad the disease is
and turn to immunisation for protection.
As more and more of the population get immunised,
hopefully the disease disappears altogether
and the immunisation programme can be stopped.
Smallpox has already been eradicated and polio may follow soon...
