Hypocrisy
of America’s experimental Ebola drug
By Theophilus Ilevbare
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 has 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.
