These
days, nothing strikes a bout of panic and paranoia than the thought of Ebola
Virus Disease. It’s been decades since a disease or calamity of such
proportions threatened our relationships, businesses, sports and our very
existence.
In
the midst of all the trepidation came a ray of hope – an experimental secret
serum, manufactured by California based Biopharmaceutical giant, Mapp. It has
been administered to two Americans and a Spanish Priest (first European), all
infected in Liberia.
The
Priest lost the battle against Ebola despite receiving the experimental
solution after he was flown back to his country, Spain. However, the health of
Dr Kent Brantly and missionary aid worker, Nancy Writebol, has improved
tremendously to reinforce the efficacy of the drug, ZMapp.
After
the malady had claimed the lives of over a 1000 people in Africa with just
about the same number presently inflicted with the disease, the American
government in collaboration with the World Health Organisation (WHO), on
compassionate grounds, sent experimental samples to Liberia for trials on Ebola
patients.
It
is puzzling why over a thousand Africans had to die before talks of a vaccine
hit the airwaves. It is safe to conclude that had the two Americans not
contracted the virus we won’t be close to any drug of any sort. Before now, the
research for a cure had been shrouded in secrecy by the Americans.
That
the ailment had no cure and is a fast moving outbreak gives a technical
knockout to the argument of ethics – that the vaccine should first be tested on
compatriots of the researchers and manufacturers in America.
The
laboratories of American pharmaceutical companies were not short of promising
research experiments of vaccines or drugs. They weren’t eager to develop a
vaccine if they aren’t sure who would buy it. With just over a thousand deaths,
it’s just a blip compared to the mortality rate of other diseases. For
instance, Malaria kills a child every minute.
Compare
the death rate of Malaria with other deadly diseases you’ll discover why
GlaxoSmithKline and other Pharmaceutical giants are making billion dollar
investments, researching and working day and night for vaccines for malaria.
Ebola is horrifying, but it’s also sporadic — between the big 2001 outbreak and
this one, only a few dozen people have gotten sick every year or two.
The
current outbreak has spread among a handful of poor countries that all have
weak health infrastructure. America and the rest of the developed world knew
the deadly disease had no known cure but since it has mainly being affecting
only Africans in several outbreaks since 1976 it wasn’t worth any serious
research investment.
Ebola
vaccine not the answer?
But
even if any of the drugs on trial works, it would be a stretch to say we could
confidently use it to prevent another Ebola outbreak. The
experimental Ebola vaccine, ZMapp, or any other one for that matter, it appears
might not even be the answer to the ravaging strain of the virus. A well-funded
and researched vaccine would have done the magic like it was the case for
smallpox and polio which put an abrupt end to outbreaks.
The
exigency of a cure for the scourge has made relevant authorities approve the
use of some experiment solutions on compassionate grounds. Anyone receiving a
rushed mass vaccine like this is putting an enormous amount of trust in
Pharmaceutical companies and the government because there is no way to know the
long term effects of the disease.
It
can’t be easily ascertained at the moment. The fears of its long term effect
exist no matter how infinitesimal it might seem. The memory of all the kids,
who now suffer from a severe form of narcolepsy due to the swine flu vaccine
that was hurriedly created a few years ago, remains evergreen.
Before
we can say uhuru, the efficacy of such a drug should cut across the various
strains of Ebola. The current outbreak is the Zaire virus, but previous
outbreaks were Sudan and Cote d'Ivoire strains. The drugs being bandied about might
not be the quintessential Ebola elixir that we crave.
Most
of the experimental drugs are solutions to fight the Zaire virus strain. These
experimental drugs can kill the present virus in the body system and prevent it
from infecting others but it does not in any way make us completely immune from
the virus, that is, another outbreak.
Containing
the scourge would have been much easier with vaccination at the early stage of
the outbreak; it is difficult to stop the epidemic in fast moving diseases like
Ebola. According to Community Health professionals, most vaccines take a few
weeks to provide immunity, and even then, they don’t always control the disease
spread. A recent WHO statement submitted that even if any of the drug or
vaccine is successful, it will take at least six months to contain the
outbreak.
During
the early weeks of the pestilence, villagers in Liberia, Sierra Leone and
Guinea blocked streets, preventing doctors and health workers from gaining
access to Ebola patients. This will pose a problem to vaccination if it
eventually becomes available.
We
heard on good report that at a point, soldiers were deployed to hospitals to
prevent locals from forcefully taking away Ebola patients. There are still
remote villages and communities in Nigeria that resist polio vaccination.
They
see it as an unwarranted intrusion from the ‘white man’. Imagine what would
happen if we tried to pre-emptively vaccinate thousands of people who not only
are skeptical of Western medicine but have never heard of Ebola.
Fighting
the epidemic must involve a multi-pronged drug. ZMapp serum, other drugs from
Canada and the one by some Nigerian doctors in the Diaspora, focuses on
eradicating the disease after infection. What the global community needs is a
vaccine to prevent the infection from getting into the body, that is the
development of antibodies within the subject rather than injecting them from
outside the body.
The
serum is by no means the end of Ebola but it leads us away from ineffective
containment of the deadly virus disease. The use of vaccine or drug might not
be the fastest way we bring the spread of this highly infectious malady to a
stop. Nevertheless, the Ebola story is not all gloomy as 40 percent of victims
are surviving.
For
now, Ebola patients will jump at the chance to live free of the virus than
worry about any side effects in the long term or another outbreak in the
future.
This
is hoping that these limited doses of the vaccine will not distract and
ultimately derail effort to curb the frenzied outbreak using tried, tested and
true methods like rapid identification and isolation of the sick and providing
basic supportive care for patients, finding and educating who’s been in contact
with them and strict hospital infection control. With these, Ebola can slowly
but surely be driven away.
