IMPORTANCE OF VACCINES AND THEIR IMPACT ON PUBLIC HEALTH
Vaccines are probably the most useful and cost-effective public health
tools known to mankind for preventing diseases. Vaccines are complex
biologic agents which give you immunity against a particular disease
without you getting sick first. They contain either the weakened
disease-causing germs, which are either killed, attenuated, or a part of
this disease-causing germ. Apart from the antigen, vaccines also contain
some other components such as adjuvants which increase the potency
of a vaccine, stabilizers which increase the stability of a vaccine and
additives which are added during the manufacturing process.
Remember that investing money in vaccination is a much wiser
decision than spending money on readymade baby foods. Once a child
suffers from an infection, parents not only have to spend a huge amount
in treatment, there is also loss on a number of school days, abstinence in
work by parents and other social issues. And due to the emergence of
antimicrobial resistance and other cause, we cannot guarantee
successful treatment too for all infections.
Vaccines are among the top 20 discoveries in the history of science. We could successfully eradicate
smallpox from the world; eliminated polio from all but two countries in the world; expect to eliminate
measles in the next 5 years; and reduce infection and death to a negligible number from diseases such as
diphtheria, tetanus, rabies, whooping cough, hepatitis B, typhoid, chickenpox, etc.
