Facts about Pertussis Outbreak in Vermont (1996)

“Because of the cyclical nature of pertussis outbreaks, periodic reemergence of pertussis epidemics can be anticipated.” – CDC MMWR Weekly, September 05, 1997 / 46(35);822-826 

In 1996, over 280 cases of pertussis cases were identified here in Vermont.
Here is the breakdown of the age groups of those infected:

12 (4%) were aged less than 1 year
32 (11%) were 1-4 years
42 (15%) were 5-9 years
129 (46%) were 10-19 years
65 (23%) were greater than or equal to 20 years

How many of these 215 children were vaccinated? According to the report, of the children who had a known vaccine status,

5 children aged 7-47 months were partially vaccinated
14 children aged 7-47 months were vaccinated with 3 doses
49 children aged 7-18 years were partially vaccinated
106 children aged 7-18 years were fully vaccinated
Disturbingly, 174 children were vaccinated and over half (61%) of the school children were considered “fully vaccinated!” It’s also important to keep in mind that in 1996, 97% of children aged 19-35 months in Vermont had received three or more doses of DT or DTP vaccine (the “schedule” recommendation at that time).

Complete failure in vaccinated children: at least 80.9%
