Blog #2 Recovering Past Roadblocks to Build
a Promising Ebola Vaccine
Several scientists have been
trying to create the vaccine that has the ability to cure and prevent the Ebola
disease. In Dr. Nancy Sullivan’s case,
it has been numerous trials and errors for 16 years and she has not found any
success. Any time a potential vaccine
for Ebola is created, it is tested on patients that are diagnosed with the
disease and await the results. There has
been a recent push for an Ebola vaccine for fear of another resurgence in West
Africa during the rainy season. Dr.
Bruce Alyward of the World Health Organization stated, “Waning cases make it
more difficult to tell if a vaccine is protective, but the shots will be tested
in multiple places and ways, hoping that one of those will give us real data. Even early vaccine attempts made by
scientists have failed. The reason for
this is because the Ebola virus is very large and infects the cells of the body
in an unusual and unique way. Their goal
is to create a vaccine powerful enough to produce an immune reaction-response
that blocks and binds the Ebola virus.
For several years, scientists have ran a myriad of tests on monkeys
infected with the virus. In 2000, a vaccine
protected four monkeys against the Ebola virus, but the vaccine required
several shots over a period of several months.
They also had no idea how to create an alternative form of the vaccine that
would produce the same results when administered to humans. The vaccine must be useful during Ebola
outbreaks as well.
I found it very
disheartening that a vaccine for the lethal Ebola disease has yet to be
created. There have been so many lives
taken by the disease this year alone, and the death toll continues to
rise. It is also very important to find
a cure because there is an elevated chance of a large global outbreak, in which
no one is fully prepared for. I do
believe that scientists are very close to a cure for the disease; however, time
is running out. The severe outbreak in
West Africa places even more pressure on scientists. The task of creating a cure that successfully
works on humans will be a difficult one.
