What is an Immunization?

What is an Immunization?
Louis Pasteur created the first live attenuated bacterial vaccine (chicken cholera) in 1879.

August is National Immunization Awareness Month (NIAM) 

Some people choose not to get immunized for various, often legitimate reasons. This blog does not support one view over another. It has been written for National Immunization Awareness Month.

The National Public Health Information Coalition (NPHIC) and the CDC have partnered to establish NIAM. During each week of NIAM the focus is on a different state of life: 

Babies and young children (July 31-August 6)
Pregnant women (August 7-13)
Adults (August 14-20)
Preteen/Teen (August 21-27)
Back to School (July/August)

What is Immunization? 
When we get sick our bodies make antibodies. These antibodies fight disease and illness to help us get well. Even once the disease or illness is gone the antibodies stay in our bodies and continue to protect us from that same illness again. But, immunity can also be developed through immunization. 

Immunity through immunization takes place when you get a vaccine that contains the same or parts of the antigens that caused the disease. The vaccine triggers an immune response. Once you are immunized memory cells, which are immune cells, act to prevent reinfection when they come into contact with the disease again. Some vaccinations, like tetanus, require boosters to maintain immunity. 


Vaccines, vaccinations, and immunizations are not the same thing

Vaccine: Product that produces immunity from a disease and can be administered through needle injections, by mouth, or by aerosol.
Vaccination: The injection of a killed or weakened organism that produces immunity in the body against that organism.
Immunization: The process by which a person or animal becomes protected from a disease. Vaccines and some diseases cause immunizations. 

Statistics

Diphtheria, Tetanus, Pertussis (4+ doses DTP, DT, or DTaP): 84.6%
Polio (3+ doses): 93.7%
Measles, Mumps, Rubella (MMR) (1+ doses): 91.9%
Haemophilus influenzae type b (Hib) (primary series + booster dose): 82.7%
Hepatitis B (Hep B) (3+ doses): 92.6%
Chickenpox (Varicella) (1+ doses): 91.8%
Pneumococcal conjugate vaccine (PCV) (4+ doses): 84.1%
Combined 7-vaccine series: 72.2% 

Influenza Vaccination 
6 months to 17 years who received an influenza vaccination during the past 12 months: 49.9%
18-49 years who received an influenza vaccination during the past 12 months: 31.8%
50-64 years who received an influenza vaccination during the past 12 months: 45.2%
65 years and over who received an influenza vaccination during the past 12 months: 67.2%

Pneumococcal Vaccination
65 years and over who had ever received a pneumococcal vaccination: 66.9%


Brief History
1879 Louis Pasteur created the first live attenuated bacterial vaccine (chicken cholera)
1884 The first live attenuated viral vaccine (rabies) was developed by Louis Pasteur, using dessicated brain tissue inactivated with formaldehyde.
1885 Louis Pasteur first used rabies vaccine in humans.
1896 Cholera and typhoid vaccines were first developed.
1908 The first county health departments in the U.S. were formed.
1914 Typhoid vaccine was first licensed in the U.S.
1914 Rabies vaccine was first licensed in the U.S.
1945 Inactivated influenza vaccine was first licensed in the U.S.
1952 The worst recorded polio epidemic in U.S. history occurred with 57,628 reported cases
Apr 12, 1955 The first polio vaccine was licensed -- an inactivated poliovirus vaccine (IPV) pioneered by Dr. Jonas Salk.
1966 The World Health Assembly called for global smallpox eradication.
1971 CDC recommended discontinuation of routine vaccination for smallpox in the U.S. following a greatly reduced risk of disease.
May 8, 1980 The World Health Assembly certified the world free of naturally-occurring smallpox
