So, yesterday I had a call from kinder saying a child (who is vaccinated) has been diagnosed with Whooping Cough. Mr 4 has already started antibiotics and will be back at kinder on Monday.
However, none of the other kids (all vaccinated), besides the infected child, in his group of 25 children is taking the antibiotics, because they have been vaccinated.
In the general population Whooping Cough vaccine (DTaP) has between 80-90% efficacy. So in a group of 24 vaccinated children, statically 4-5 of those children do not have enough immunity to prevent catching, and spreading the disease.
As well as this, up to 25% of all Whooping Cough cases are thought to by asymptomatic (no symptoms), and most of those cases are found in adults and vaccinated children.
So, theoretically, one of the children who is vaccinated in the group may have contracted Whooping Cough from the infected child, and will not develop symptoms but will spread the disease.
I have long believed there should be annual testing of immunity levels in the vaccinated population. This is commonly done in animals - their antibody titers are tested annually.
So, why is this not done for our children, would that not increase herd immunity? (not that I believe in herd immunity, but for all those people who do...)
If vaccinations are to be treated seriously, surely it pays to make sure children are immune. Many people find out in early pregnancy that they have not developed immunity to Rubella despite repeated immunisation, surely similar testing should be done for all vaccines!
WDYT - please try to stay on topic and resist the urge to lecture me on not vaccinating.
In case you are unclear of the question, I am asking, 'Should post-vaccination immunity levels be tested to prove immunity?'
