Essay title: Vaccine-Preventable Diseases
Vaccine
Most vaccine-preventable diseases are caused by germs that are called “viruses” or “bacteria.” Vaccines to help prevent these diseases generally contain weakened or killed viruses or bacteria specific to the disease. Vaccines help your body recognize and fight these germs and protect you each time you come in contact with someone who is sick with any of these diseases.
There are a series of steps that your body goes through in fighting these diseases:
First A vaccine is given by a shot (influenza vaccine may be given by a nasal spray).
Next Over the next few weeks the body makes antibodies and memory cells against the weakened or dead germs in the vaccine.
Then The antibodies can fight the real disease germs if the person is exposed to the germs and they invade the body. The antibodies will help destroy the germs and the person will not become ill.
Finally Antibodies and memory cells stay on guard in the body for years after the vaccination to safeguard it from the real disease germs.
WHY
• vaccines prevent disease in the people who receive them and protect those who come into contact with unvaccinated individuals.(protacts the community)
• Small children needs vaccination for future diseses because their maternity immunity doesn’t last long.

• 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).
