There’s been a recent outbreak of whooping cough (pertussis) in Hunterdon County, NJ, and the last report I’ve seen puts the number of ill children at 32.  A separate news report stated that the ill children had been vaccinated,  and then another report confirmed that all the infected children had all of their recommended vaccines.

Most of the infected children were (29/32) between the ages of 7-12.  These children, if vaccinated according the CDC recommendations, had DTaP shots at ages 2 months, 4 months, 6 months, 15-18 months and 4-6 years.  That’s FIVE doses.  Five doses of the vaccine, and still this many children are not immune?

There’s been a recent addition of a SIXTH dose of pertussis in New Jersey near age 10, as there is concern that the temporary immunity to pertussis from the previous five doses wanes as quickly as ages 7-9.

Apparently when five doses of a vaccine aren’t sufficient to induce immunity the answer is to just keep giving more doses, as perhaps after the 10th, 25th or 33rd dose they will hit the jackpot.  If we’re lucky.
