Why Are Immunizations So Important?
Immunizing Prevents Disease
Disease prevention is the key to public health. It is always better to prevent a disease than to treat it.
Vaccines prevent disease in the people who receive them and protect those who come into contact with unvaccinated
individuals. Vaccines help prevent infectious diseases and save lives. Vaccines are responsible for the control of
many infectious diseases that were once common in this country, including polio, measles, diphtheria, pertussis
(whooping cough), rubella (German measles), mumps, tetanus, and Haemophilus influenzae type b (Hib).
Vaccine-preventable diseases have a costly impact, resulting in doctor's visits, hospitalizations, and premature
deaths. Sick children can also cause parents to lose time from work.
How the Body Defends Itself
Each child is born with a full immune system composed of cells, glands, organs, and fluids that are located
throughout his or her body to fight invading bacteria and viruses. The immune system recognizes germs that
enter the body as "foreign" invaders, or antigens, and produces protein substances called antibodies to fight
them. A normal, healthy immune system has the ability to produce millions of these antibodies to defend against
thousands of attacks every day, doing it so naturally that people are not even aware they are being attacked
and defended so often (Whitney, 1990). Many antibodies disappear once they have destroyed the invading antigens,
but the cells involved in antibody production remain and become "memory cells." Memory cells remember the
original antigen and then defend against it when the antigen attempts to re-infect a person, even after many
decades. This protection is called immunity. It’s true that newborn babies are immune to many diseases because
they have antibodies they got from their mothers. However, the duration of this immunity may last only a month
to about a year. Further, young children do not have maternal immunity against some vaccine-preventable diseases,
such as whooping cough. If a child is not vaccinated and is exposed to a disease germ, the child’s body may not
be strong enough to fight the disease.
Immunizing Slows the Spread of Disease
Before vaccines, many children died from diseases that vaccines now prevent, such as whooping cough, measles,
and polio. Those same germs exist today, but babies are now protected by vaccines, so we do not see these
diseases as often. protected by vaccines, so we do not see these diseases as often. Immunizing individual
children also helps to protect the health of our community, especially those people who are not immunized.
People who are not immunized include those who are too young to be vaccinated (e.g., children less than
a year old cannot receive the measles vaccine but can be infected by the measles virus), those who cannot
be vaccinated for medical reasons (e.g., children with leukemia), and those who cannot make an adequate
response to vaccination. Also protected, therefore, are people who received a vaccine, but who have not
developed immunity. In addition, people who are sick will be less likely to be exposed to disease germs
that can be passed around by unvaccinated children. Immunization also slows down or stops disease outbreaks.
