SPIN CITY: THE MARKETING OF A VACCINE CAMPAIGN
Around a million New Zealanders, many of them children, are being targeted in what some are calling a public scare campaign - TV commercials, schools and daycares enlisted to terrify parents into authorising the meningitis jab for their kids. But, as BARBARA SUMNER-BURSTYN writes, are we being played for suckers?
For the past 13 years an uncontrolled epidemic has raged in New Zealand, maiming or killing hundreds of New Zealanders, mainly the young.’ So began one of many recent New Zealand Herald exposés on meningococcal disease. Detailing the horrific effects of meningitis being suffered by two Auckland babies, Charlotte and Junior, I cried and like many New Zealanders was hooked on their tragic stories. Newspapers across the country filled up with letters, columns and editorials about the disease and the vaccination that would release us from its grip. Then the NZ Herald ran an article extolling an educational program in South Auckland schools. The accompanying picture showed a cozy classroom of five year olds playing with oversized, multicolored cubes with words like scarring and death attached to the sides. And it dawned on me: we may be in the middle of an epidemic but we are also in the middle of a massive advertising and promotion campaign. In many ways it’s an entirely new public health environment where the concept of informed parental consent is being undermined by direct advertising to children and where vaccination is being turned into a moral duty, the gold standard of good parenting that only the most careless caregiver would shun.
But as recently as January 2000 Health Minister Annette King was extolling the findings of a landmark two-year Meningococcal Disease study that clearly demonstrated the link between the disease and poor housing and overcrowded living conditions. “Members of this government have been saying that for years, but the link was consistently denied by Jenny Shipley and members of her former government,” she said.
But to Dr Jane O’Hallahan, the Director of the Meningococcal B Immunization Programme it was never that simple. “The poverty theory,” she says, “oversimplifies a complex situation.”
She’s right. Meningococcal disease, and New Zealand’s experience with it, is far more complex than the Ministry of Health’s glossy brochures, their website or any of the articles and information promoting vaccination would have us believe.
Take risk as an example. I’m a middle class Pakeha with a reasonable standard of living. If I had a baby would she be at risk? Yes, says Dr O’Hallahan, citing the ‘devastating epidemic’ we’re in the middle of.
But calculating out the MOH’s own figures that show 5400 of us have contracted the disease and 220 have died from all strains of it, the risk for New Zealanders suffering from the Nesseria meningitides B strain, the one causing all the trouble, is 0.007%. Put another way, 99.993% of us will not fall ill from meningitis. Of those who do and survive, up to a fifth are left with disability. At the latest figures that’s a total of 1,080 New Zealanders over 13 years, or just 18 people a year.
While we’ve been in the grip of this ‘uncontrolled epidemic’ 203,387 New Zealanders were injured on our roads and 7632 were killed. While Looking Upstream - a Ministry of Health report released in March - estimates 11,000 people die from diet-related causes such as heart disease every year. That’s 30 per cent of all deaths, far eclipsing deaths from tobacco, drugs, alcohol, motor accidents, violence and meningitis.
And it turns out the bugs that cause meningitis are fairly common. The Ministry of Health, whose figures are based on nasal swabbing, recently found 22 percent of students swabbed in Otago carried meningococcal bacteria, with only two percent carrying the B strain. But in 2000 the Lancet reported that by doing the far more accurate tonsillar tissue test, the disease could be found in 45% of the population. Studies also found that despite such high carriage rates and the mobility of the bacteria, progression to invasive disease occurs only rarely.
Add all this to a 1982 study that showed natural immunity to meningitis is reinforced throughout life by repeated and intermittent carriage of different strains, and you have to ask why some of us are so susceptible to this cruel disease, while for others it’s self-limiting and harmless?
For a start numerous studies have found associative factors such as parental smoking, Vitamin C levels, panadol use, overcrowded, unhygienic housing conditions and iron anemia are all irrefutably linked to the disease (a recent Auckland study found iron deficiencies in 29% of young New Zealand children). In June, New Scientist magazine said an extensive survey of baby foods has found the presence of a bacterium linked to a handful of fatal outbreaks of meningitis. The magazine said the meningitis-causing bug has been found in powdered infant formula before, but this study was the first to detect it in dried infant food. Premature babies and those with a weakened immune system are at particular risk, they said.
Meanwhile a 2001 study from the Netherlands found convincing evidence of genetic background in the invasion of meningococci.
Since genetic testing is, for now, out of the question, and the vaccine has been found not to confer herd immunity – meaning only the individual and not their wider community is protected, and nutrition as a preventive seems to have fallen out of favor, perhaps there’s a way for an individual to find out if they’re already immune.
I phone a range of doctor’s surgeries and ask if there’s a test. The answer is similar at each. “We’ve not been given any information on that.” “There is no test.”
Of course there is a test. But like everything with this disease, it’s not that simple.
The trials, run by Dr Diana Lennon at Auckland University, have shown a minimum of three vaccinations is necessary to raise antibody levels. And despite the fact the opening statement on the official consent form says: Parents/Guardians this is all it takes to protect them, up to 25 per cent of participants gained little or no immunity.
How do they know that? “It’s a blood test,” says Dr Lennon. But then she goes on to say it won’t be available to the public because there is no clear point at which it can be said that antibodies are conferring immunity.
Pardon?
“Decisions on the efficacy of the vaccine are made on a population base, not an individual level,” she says, “therefore an antibody test prior to or between receiving the vaccine would be meaningless.” She admits it took her ages to cotton on to the concept. With less time to dwell on it, it strikes me that it’s only meaningless for those of us who want to know if our children have natural immunity, while for the trial participants, for the licensing committee, for the government spending 200 million, it’s the primary way of assessing the efficacy of the vaccine. In other words, it makes no sense to use antibodies as proof of acquired immunity and then say that antibodies are not a good measure of immunity.
So given the MOH intends to vaccinate one million New Zealanders it seems appropriate to find out just exactly what’s in that little vial of clear liquid. When asked by a group of concerned parents about the ingredients besides those published on the data sheet (outer membrane vesicles,1.65 mg of aluminum and histidine) MedSafe, the government organization responsible for safety in medicine was unequivocal. That information is withheld under the provisions of the Official Information Act on the grounds that it’s not in the public interest to know.
Okay, how about the vaccine culture, the agents used to deactivate the bacteria and agents used to purify the vaccine?
“Withheld.”
