These
Three Diseases Could Be the Next Global Epidemic
A half-billion-dollar
project announced at the World Economic Forum in Davos aims to develop vaccines
against the deadly MERS, Lassa and Nipah viruses.
With the world still
reeling from outbreaks of deadly Ebola and baby-deforming Zika, governments and
charities launched a $460-million (431 million-euro) initiative Thursday to
“outsmart” infectious epidemics.
The goal is to develop
vaccines with which to contain outbreaks before they become global health
emergencies, the creators of the Coalition for Epidemic Preparedness
Innovations (CEPI) announced at the World Economic Forum in Davos. And they should be
available free of charge.
“We know that epidemics
are among the significant threats we face to life, health and prosperity,” said
Jeremy Farrar, director of the Wellcome Trust, a health research charity which
backs the project.
“Vaccines can protect
us, but we’ve done too little to develop them… CEPI is our chance to learn the
lessons of recent tragedies and outsmart epidemics with new vaccine defenses.”
The priority will be
vaccines against the highly contagious and fatal Middle Eastern Respiratory
Syndrome (MERS) as well as the Lassa and Nipah viruses, which can cause serious
epidemics.
The coalition will aim
to create two trial vaccines for each of these viruses “so that these are
available without delay if and when an outbreak begins.”
“Ebola and Zika showed
that the world is tragically unprepared to detect local outbreaks and respond
quickly enough to prevent them from becoming global pandemics,” said
billionaire CEPI backer Bill Gates.
About 11,300 people
died in a 2013-16 Ebola epidemic in Guinea, Liberia and Sierra Leone — the
worst outbreak by far in the disease’s 40-year history.
Finish the job on Ebola
Since 2015, more than
2,200 babies in Brazil have been born with microcephaly, a crippling
deformation of the head and brain, in an unprecedented outbreak of the
mosquito-borne Zika virus.
The race is on to
develop vaccines against both diseases, but none has been registered yet.
So far, CEPI has
received money from Germany, Japan and Norway, the Bill & Melinda Gates
Foundation, and the Wellcome Trust — raising almost half the $1 billion needed
for its first five years of operation.
The economic damage
caused by epidemics is matched only by wars and environmental disaster,
Norway’s Prime Minister Erna Solberg said in Davos.
“Guinea, Sierra Leone
and Liberia suffered an economic loss of at least $3 billion as a result of
Ebola, and we know that SARS cost $40 billion.”
Andrew Witty, chief
executive of CEPI participant GlaxoSmithKline, said the initiative would seek
to develop vaccines through Phase I safety and Phase II efficacy trials.
This way, when an
outbreak happens, the drug can be quickly put through Phase III testing in a
larger group of people — the final stage before licensing.
“Ideally we do five or
six” vaccines, said Gates, though “at our current funding level it is more
likely that we will be able to do two or three.”
For Farrar, this should
include “finishing the job on Ebola” — for which several vaccine candidates
have proven effective in trials.
“We have to be able to
have a licenced vaccine that can be used tomorrow when the inevitable epidemic
of Ebola comes back,” he said.
The greatest mistake,
added Farrar, would be “to do what we did after SARS, and that is to forget it
and move on.”
A 2003 outbreak of the
deadly respiratory disease infected people in nearly 40 countries within weeks
and caused global panic. It claimed 800 lives, mainly in Asia.
The coalition said it
would need “significant additional investment”, and urged more governments and
charities to join the initiative.
Other participants
include the World Health Organization, several NGOs and pharmaceutical
companies.
