In the 1920s the first vaccine for diphtheria was developed. Soon after, vaccines for pertussis and tetanus toxoid were developed and in 1925 the three vaccines were combined, becoming what is now known as the DTP vaccination. These vaccinations were developed in an effort to reduce childhood morbidity and mortality rates from infectious disease.
 
Vaccination programs have changed significantly since 1925, even in the past 10 years. Today, children receive not only the DTP and MMR vaccinations, but also Hepatitis A, Hepatitis B, HiB, Influenza, Polio, Varicella (chicken pox). Additional vaccinations may also be recommended depending on a child”s health.

The readings this week focused on the body”s immune system and how vaccinations can help the body protect against infectious disease. With these thoughts in mind, consider at least one example of vaccination efforts for a particular infectious disease (this could include efforts to create a vaccine).

Post by Day 4a response to the following:

• Choose any disease except influenza for which a vaccine is relevant (either a vaccine exists or is needed) and discuss how knowledge of immunology is applied to public health policy, programs, and/or practice for that disease. You may not choose influenza because it is the subject of week 7.
• Include any applicable discussion on the historical context of the disease, focusing on vaccination and eradication efforts.

Support your discussion by citing at least one primary research article.
