THE REASON WE IMMUNIZE
Achievements in Public Health, 1900-1999 Impact of Vaccines
Universally Recommended for Children -- United States, 1990-1998
At the beginning of the 20th century, infectious diseases were widely prevalent in the
United States and exacted an enormous toll on the population. For example, in 1900,
21,064 smallpox cases were reported, and 894 patients died (1). In 1920, 469,924
measles cases were reported, and 7575 patients died; 147,991 diphtheria cases were
reported, and 13,170 patients died. In 1922, 107,473 pertussis cases were reported, and
5099 patients died (2,3).
Dramatic declines in morbidity have been reported for the nine vaccine-preventable
diseases for which vaccination was universally recommended for use in children before
1990 (excluding hepatitis B, rotavirus, and varicella) . Morbidity associated with smallpox
and polio caused by wild-type viruses has declined 100% and nearly 100% for each of the
other seven diseases.

ARE VACCINES SAFE?
AND WHAT’S VAERS ANYWAY?
Vaccine Adverse Effects Reporting System
VSD
THE VACCINE SAFETY DATALINK
This is the most robust vaccine safety system; there are others (example: military).
THE ROTASHIELD® STORY (BORN 1998, DIED 1999)
•
Rotavirus kills some 450,000 children per year around the world; 20-60 in the United
States
•
Early 1990s , clinical trials showed 80-100% effectiveness against severe rotavirus
diarrhea and excellent safety profile
•
1998: RotaShield licensed
•
Late 1998: reports to VAERS of many cases of intussusception after RotaShield receipt
•
VAERS Signal reported to VSD, which affirmed the hypothesis that RotaShield
associated with intussusception
•
1999: Rotashield removed from market.
•
Early 2000s, clinical trials on far more children showed no association with
intussusception for two new vaccines, Rotarix® and Rotateq®
•
2006: Rotarix and Rotateq approved by FDA and recommended by ACIP

But no, folks, you
won’t have to pay
for vaccines in
New Mexico (yet).
IN 42 STATES…
But only for
• Uninsured
• Native Americans/Alaska
Natives
• Medicaid insured
• Underinsured
• But only in FQHC or RHC
IN 6 STATES (NH, RI, VT, WI, WY AND…
NEW MEXICO!)
For all children and
adolescents before
their 19th birthday
Alaska, Hawaii, Maine, Massachusetts, South Dakota, Washington
cover most but not all childhood vaccines
ARE THESE VACCINES AFFORDABLE?
In Arizona, Colorado, Utah, Texas and most other states, the total private sector price of all
vaccines for each person (except influenza) through age 18 was $2171 + vaccine
administration as of April 2014.
In New Mexico, the price to patients is $0 + vaccine administration
