The risk to
all of us in a malaria vaccine, whether we vaccinate or
not, is enormous. This study demonstrates that a more
virulent and deadly form of malaria is a near-certain
outcome. |
Blood-filled
Anopheles Mosquito
Malaria is a killer.
Obviously, the last thing we need is a more virulent malaria.
Yet, that is precisely
what the malaria vaccine will probably cause. A study published by
PLoS Biology found that “virulence evolved” through malaria
vaccinations.
Malaria is a disease that causes severe chills, fevers, sweats,
fatigue, and anemia. It’s caused by Plasmodium parasites, which are
carried by the Anopheles mosquito. It’s transmitted through the
mosquito’s “bite” when it feeds. Unlike other diseases, its symptoms
have a nasty tendency to return, often years after initial
infection.
For people in the northern hemisphere, malaria hasn’t been much of a
problem, but with climate change’s warming, the malaria-carrying
mosquitoes have moved further north and now pose risks to North
America and Europe.
This, of course, means that an enormous new profit center is
developing for malaria vaccines. Therefore, there’s been a burst of
research to develop them. Of course, such research is focused on one
thing: bringing a product to market. Concerns about the long term
effects are not addressed by vaccine researchers. Fortunately,
though, one team of scientists has investigated the potential risk
of such a vaccine.
The findings should give
pause to the gung-ho vaccine developers - but almost certainly
won’t.
Genetically
Engineered Vaccine Concerns
Most research into new vaccines tends to utilize recombinant DNA
technology.
That is, they are
creating genetically modified organisms to make vaccines. These
vaccines are generally created by implanting a gene that causes a
plant to make a molecule that becomes an antigen in a vaccine. These
antigens are bits of proteins, which are called epitopes when
antibodies are created against them.
According to the study, several vaccine-created epitopes are known
to evolve, resulting in ineffective or less effective vaccines.
Specific diseases referenced include the hepatitis B virus,
Bortadella pertussis (whooping cough), and Streptococcus pneumoniae.
Although the evolution of epitopes is a concern with some vaccines,
there is another, even more serious worry. The possibility of
vaccinations causing the evolution of the infectious agents
themselves was the focus of this study. As the authors state:
Vaccination could favor virulent malaria parasites in two ways.
First, [point 1] if the primary force preventing the evolution of
more virulent strains is that they kill their hosts and therefore
truncate their infectious periods, keeping hosts alive with
vaccination will allow more virulent strains to circulate. Second,
[point 2] immunity might be less effective against virulent strains.
["Point 1" and "point 2" added by me.]
Their first point is that vaccines may result in more virulent forms
of a disease by removing it from the pool of variants, which can
result in their place being taken by a more virulent disease. As
discussed in
Whooping Cough Epidemic Caused by Virulent New
Pertussis Strain - And It’s the Result of Vaccine, this has been
known to happen in the case of pertussis, and is behind much of the
current whooping cough outbreaks.
The second point of concern is simply that the vaccines may not be
as effective against more virulent strains. This point is already an
issue, as in the case of the vaccine-induced more virulent strain of
pertussis.
Leaky Vaccines
Further complicating the issue is that any malaria vaccine is
“leaky”.
The term leaky refers to
a vaccine that does not kill all of an individual’s disease-causing
agents. This study documented that malaria vaccines are, indeed,
leaky.
The risk is that infections of evolved organisms can be spread from
one individual to another through mosquitoes. If a person with an
evolved and more virulent Plasmodium parasite is bitten by a
mosquito, it can be transmitted to other people. The mosquito has
become a carrier of the newly evolved Plasmodium parasite.
This study found that more severe symptoms developed in mice after
Plasmodium had been passed through only ten individual mice through
leaking.
RedOrbit reports lead author Andrew F. Read as
saying:
Leaky vaccines
create a situation that further fosters parasite evolution. The
parasites that are able to survive in the immunized hosts must
be stronger after having survived exposure to the vaccine. The
vaccine-induced immunity apparently removed the less virulent
malaria parasites, but left the more virulent ones.
RedOrbit
also quotes
Victoria Barclay, who conducted the laboratory experiment:
We were surprised to
find that more-virulent strains of malaria evolved even while
the gene encoding the key antigen remained unchanged. We did not
detect any changes in the gene sequence.
The Inherent Danger
to All of Us
Read says that ongoing monitoring needs to be done to see if a
malaria vaccine causes more virulent strains of malaria.
But frankly, that simply
isn’t good enough. By the time any monitoring system discovers that
an already deadly disease has evolved to become even more virulent,
it’s too late.
The new, more deadly
strain, is already out there.
Though the authors leave the impression that the vaccines will
likely continue to protect against these more virulent diseases, the
reality is that they don’t know it. We already know that the
slightest variance in an influenza virus results in a new disease
unaffected by existing vaccines.
The fact is that scientists, medical doctors, and health agencies
are playing games with our lives. At some point, an untreatable and
unstoppable disease is almost certain to arise as a direct result of
the vaccines being pushed. In the case of malaria, we’re already
dealing with a particularly nasty disease, one that causes
tremendous misery and death. How much of a mutation is required for
it to become an uncontrollable pandemic?
We don’t know. But that doesn’t stop them.
Nothing seems to even
slow the profit-making vaccination juggernaut.
