Amid fears of a looming pandemic, scientists in the US and across the
globe are scrambling to develop vaccines – including in Israel, where
one group of researchers says it could be ready in just three weeks and
available for use within 90 days.
The scientists at the Galilee Research Institute, known as MIGAL, are
adapting its vaccine against the avian coronavirus infectious
bronchitis virus, or IBV, to work for the novel coronavirus known as
COVID-19, the Jerusalem Post reported.
“Congratulations to MIGAL on this exciting breakthrough. I am
confident that there will be further rapid progress, enabling us to
provide a needed response to the grave global COVID-19 threat,” said
Ofir Akunis, Israel’s minister of science and technology.
The independent research institute, which specializes in the fields
of biotechnology, environmental sciences and agriculture, says on its
website that its team “includes 80 PhDs and a total of 260 researchers”
at 53 labs.
Its vaccine for IBV, a bronchial illness that affects poultry, has
already been proven in preclinical trials conducted at Israel’s
Veterinary Institute, according to the news outlet.
“Our basic concept was to develop the technology and not specifically
a vaccine for this kind or that kind of virus,” said Dr. Chen Katz,
MIGAL’s biotech group chief.
“The scientific framework for the vaccine is based on a new protein
expression vector, which forms and secretes a chimeric soluble protein
that delivers the viral antigen into mucosal tissues by self-activated
endocytosis, causing the body to form antibodies against the virus,” he
added.
Endocytosis is the process in which substances are brought into cells
by surrounding the material with membranes that form vesicles
containing the ingested material.
The researchers discovered that the poultry coronavirus is very
similar genetically to the human one — and that it uses the same
infection method, Katz said.
“All we need to do is adjust the system to the new sequence,” he
said. “We are in the middle of this process, and hopefully in a few
weeks we will have the vaccine in our hands. Yes, in a few weeks, if it
all works, we would have a vaccine to prevent coronavirus.”
The oral vaccine will have to go through a regulatory process, including clinical trials, he noted.
MIGAL CEO David Zigdon said the vaccine could “achieve safety approval in 90 days,” according to the Jerusalem Post.
“Given the urgent global need for a human coronavirus vaccine, we are
doing everything we can to accelerate development,” he added.
Akunis said he has instructed his ministry’s director-general to speed up all approval processes.
“We are currently in intensive discussions with potential partners
that can help accelerate the in-human trials phase and expedite
completion of final-product development and regulatory activities,” he
said.
In the US, Massachusetts-based drugmaker Moderna has sent its first
batch of an experimental vaccine – called mRNA-1273 — to the National
Institute of Allergy and Infectious Diseases for testing just six weeks
after it began working on it, according to CNN.
The biotech firm in Cambridge said the first vials of the
experimental product would be used in a planned Phase 1 study, which
involves testing on a small number of healthy people.
NIAID Director Anthony Fauci told CNN that a clinical trial could
start by the end of April, but the process of testing and regulatory
approvals would last at least a year.
He said this week that the approval process could be expedited after a
successful Phase 1 trial, but that even when proceeding at breakneck
speed, a vaccine would not be ready for use for at least a year or 18
months.
In Texas, meanwhile, scientists at the Baylor College of Medicine in
Houston who worked on a vaccine for SARS several years ago are working
on immunization against the novel coronavirus, or COVID-19.
“We know that virus is 80 percent similar to the current SARS-2 virus
that causes COVID-19, but at the same time, we’re also engineering a
potentially new vaccine that will be much more specific against the
COVID-19,” Dr. Maria Bottazzi of the Center for Vaccine Development at
Baylor told ABC 13.
Dr. Kathryn Stephenson, a Harvard Medical school professor and head
of of the clinical trials unit for the Center for Virology and Vaccine
Research at Beth Israel Deaconess Medical Center, told the Boston Globe
that vaccines must undergo extensive testing with progressively larger
groups of people.
“You can make a vaccine, but you’re not going to put that into humans
until you’re pretty confident in your product,” said Stephenson, whose
center also is working on a coronavirus vaccine.
Other companies rushing to develop a vaccine include Inovio, GlaxoSmithKline, Sanofi and Johnson & Johnson.
Meanwhile, Israeli company BATM said Thursday it has developed a
quick diagnostic kit to test for the coronavirus — and that production
was underway at a facility in Rome owned by Adaltis, which produces
medical testing devices, the Times of Israel reported.
The firm said the kit’s ability to successfully screen those carrying
the virus had been verified by several labs and hospitals, adding that
the test met criteria set out by the US Centers for Disease Control and
Prevention.
