World Health Organization to Stop Tracking Swine Flu Cases

What?!

Wait... I thought that H1N1 was such a huge threat that we needed to rush out a vaccine to everyone on the planet with as little as five days of safety testing, and that HHS "anticipated" being voluntary, but could be made mandatory for everyone.

But apparently is it also so small a threat that we don't even need to track how big the threat is any more.

You have got to be kidding me.

Apparently they mentioned this little tidbit under their breath as they were leaving a room or something, because their official spokesman was baffled when someone asked him about it.

I try very hard not to become cynical on vaccine issues and rush to blame over zealous vaccination policies on motives of financial gain, but I don't know how not to go there when the agency calling for world wide swine flu uptake stops measuring the need for such uptake.

As soon as they stop counting, no one can make the arguement that this vaccine will be necessary because we won't know how many people are actually dying from it. Which is fewer and fewer, now that the number of people infected is actually in the millions.

So we are just supposed to take WHO's advice to take a minimally tested vaccine, with out knowing if it really is necessary? Knowing full well that THEY don't even know if it is necessary?

When will health policy makers begin acting in good faith with the people who are supposed to be following their polices? Because now they know that we know that they don't even know if this shot is necessary?

I just we are just supposed to turn off our brains, not think for ourselves, have no desire to make informed health decisions and hand over our cash (via taxes, insurance premiums or actual cash) and get a shot because some people we don't know with letters after their names said so.

Come to think of it, who is the WHO anyway? Who are they accountable to, what do they know about me and my family, and why do I care what they think? If they are wrong in their recommendations and policies, or even criminal, what recourse do I have? Writing a strongly worded letter?

...becoming cynical...

W.H.O. Says It Plans to Stop Tracking Swine Flu Cases
New York Times
By DONALD G. McNEIL Jr.
Published: July 16, 2009

In a move that caught many public health experts by surprise, the World Health Organization quietly announced Thursday that it would stop tracking swine flu cases and deaths around the world.

The announcement, made in a “briefing note” posted on the organization’s Web site late in the day, perplexed some experts, and even baffled a W.H.O. spokesman, Gregory Hartl, who said in an e-mail message, “I don’t have reliable info” about what his agency would track instead.

Only a little earlier in the day, Mr. Hartl had confirmed that Argentina, with 137 swine flu deaths since June, had surpassed Mexico, where the epidemic began in February, as the country with second largest number of swine flu deaths. Mexico has 121, and the United States, with a much larger population, has 211.

The last W.H.O. update, issued on July 6, showed 94,512 confirmed cases in 122 countries, with 429 deaths.

Many epidemiologists have pointed out that, in reality, millions of people have had swine flu, usually in a mild form, so the numbers of laboratory-confirmed cases were actually meaningless. And performing the tests has overwhelmed many national laboratories.

The briefing note said countries would still be asked to report their first few confirmed cases. It also said countries should watch for clusters of fatalities, which could indicate that the virus had mutated to a more lethal form. Other “signals to be vigilant for,” it said, were spikes in school absenteeism and surges in hospital visits.

Pneumococcal Doubles Asthema Incidence

From One Click:

One Click Note: The World Health Organization states that for every 1000 children vaccinated with the pneumococcal vaccine, 1.3 children will develop asthma on account of the vaccine. At the same time only 3.6 cases of pneumonia are prevented by vaccinating 1000 children. Pneumonia is an easily treated condition. Asthma on the other hand may be a lifelong disability:

Incidence of pneumonia
is not reduced by pneumococcal conjugate vaccine

Madhi et al.1 write that the pneumococcal conjugate vaccine (PCV) is an effective instrument for pneumonia prevention in children. This is not strictly true. WHO data2 suggest that there are 450 million cases of pneumonia each year and that it causes 3.9 million deaths. In the sub-Saharan region of Africa, 1 022 000 die and 702 000 die in south Asia.1 The pneumonia referred to is “clinical pneumonia” – a diagnostic syndrome within the Integrated Management of Childhood Illness – WHO and United Nations Children’s Fund (UNICEF) system for triage and clinical management in developing countries.3 The Cochrane database4 states that PCV does not reduce the incidence of clinical pneumonia, although it has been shown to reduce vaccine-serotype bacteraemic pneumonia and radiological pneumonia. The benefit of reducing bacteraemic pneumonia and radiological pneumonia is so minimal that it has no effect on “clinical pneumonia”. Poor nations will need to assess its cost utility carefully.

A study from the Gambia showed that mortality was 16% lower in a PCV immunized group compared to placebo recipients (25.2/1000 children years versus 30.1/1000 children years).5 Data are also provided on adverse effects and deaths within 1 week of receiving any dose of the vaccine or placebo. The mortality benefit was seen in the first week after injection, well before vaccine efficacy could have been established. There were 12 deaths in the vaccine group and 15 among controls (23.8/1000 children years versus 29.8/1000 children years). This suggests that factors other than vaccine efficacy are responsible for the difference in mortality between the groups compared.

There is also another issue that we hope to raise here. The paper states that the vaccine programme would exceed the WHO threshold in 69 eligible countries. The authors assert that these findings are conservative in the sense that they did not assume any herd protection and did not assume protection beyond the age of 2.5 years. Beutels6 has cautioned against this trend of noting the “positive” uncertainties (herd immunity, protection beyond 2.5 years) without reporting the “negative” ones (serotype replacement,7 increased incidence of asthma),8 which could dampen enthusiasm for the intervention.

World Health Org Bans a Hep B Vaccine After Infant Deaths

WHO bans vaccine, sends experts to probe child deaths in Vietnam
Thanh Nien News

The World Health Organization has suspended the use of a Hepatitis B vaccine worldwide after three newborns died and another became seriously ill in Vietnam after getting shots in the last few weeks.

Nguyen Tran Hien, head of a council set up in Vietnam to investigate the cases, told the council’s first meeting that two international experts from the UN health agency would arrive in Vietnam Saturday to work with local investigators.

The cases occurred between April 23 and May 7 in Ho Chi Minh City, Ha Tinh Province, and Thanh Hoa Province.

One baby fully recovered after taking ill.

The WHO-approved vaccine is made by South Korea's LG Life Sciences and distributed in Vietnam through a UN program.

Earlier this month, Vietnam instructed all localities nationwide to stop using the vaccine.

WHO's Department of Immunization, Vaccines and Biologicals has asked that countries around the world stop using shots from the affected batches until the cause of the illness can be determined.
