Game and Fish Begins Study to Evaluate Chronic Wasting Disease Vaccine
Game and Fish Begins Study to Evaluate Chronic Wasting Disease Vaccine
2/19/2013
CHEYENNE - The Wyoming Game and Fish Department has begun a multi-year
study at its Thorne-Williams Wildlife Research Unit (formerly Sybille) near
Wheatland to evaluate the efficacy of a vaccine against chronic wasting disease.
Chronic wasting disease is a neurological disease of elk, deer, and moose.
The disease appears to be invariably fatal to the animal, but it is not thought
to affect humans.
The vaccine was developed in Canada by the Pan-Provincial Vaccine
Enterprise (PREVENT), a partnership of three leading infectious disease centers.
PREVENT works closely with academia, industry, government, and not-for-profit
sectors to accelerate vaccine development so that promising vaccines can move
readily into clinical development and production.
In January, researchers trapped 50 elk calves at Game and Fish’s South Park
feedground (south of Jackson) and transported them to the research unit. There,
calves were split into two groups. One group was vaccinated and one was an
unvaccinated control group. “Previous research has demonstrated that elk will
naturally contract chronic wasting disease by being housed at the unit,” said
Game and Fish Chief Wildlife Veterinarian Dr. Terry Kreeger. “We predict that
the vaccinated group will live longer than the control group. It’s important to
understand that even if the vaccine does not provide lifelong protection from
chronic wasting disease, every extra year of survival the vaccine provides will
mean increased production in an affected population.”
The vaccine is administered by hand at the research unit, which would not
be practical for vaccinating wild elk. However, if the vaccine is found to be
effective, future research will focus on delivery methods more appropriate for
wild elk, such as baits. At a minimum, an effective vaccine administered to elk
raised on private ranches could greatly reduce the spread of the disease.
Chronic wasting disease is thought to have been primarily spread throughout
parts of the United States and Canada by the unintentional movement of infected
deer and elk among private game ranches.
“We figured that research over time would start providing wildlife managers
with tools that could be used to combat this disease,” said Kreeger. “This is
just the start of a long journey to evaluate and perfect these tools.”
A parallel vaccine study is being conducted on deer in Colorado.

CHRONIC WASTING DISEASE CWD
Chronic Wasting Disease Testing continued for Chronic Wasting Disease (CWD)
in white-tailed and mule deer, elk, and moose in various locations of the state.
WGFD divides the state into eight administrative regions with the goal to test
500-600 deer from each region utilizing hunter harvest, road killed, and
targeted animals. Although the 2011 surveillance efforts are still underway, as
of December 1st, 2,911 deer, elk, and moose samples had been analyzed. Of these,
103 tested positive for CWD, representing 79 mule deer, 14 white-tailed deer,
and 10 elk. In 2005, the Department included moose in the CWD surveillance
program. During FY 2011, 136 hunter-killed, 37 targeted and 18 road-killed moose
were surveyed with no moose testing positive for CWD.

CWD Controversy still stalking elk feedgrounds in Wyoming 2010
Greetings,
This is very serious, please notice that one of the CWD clusters is only 45
miles from ELK feeding grounds in Wyoming, the second elk feeding ground is 98
miles from CWD cluster, and the third elk feeding ground is 130 miles from the
CWD cluster. Common sense tells us we need to stop those feeding grounds, if you
want your Elk to survive. There is no politics or plot against the hunters or
elk about it. read the science please. ...TSS

- an effective vaccine could be used to prevent CWD in game farm animals
but additional study would be required to determine an effective application
method in the wild.

Project Description
Members of our team have been focused on a disease specific epitope (DSE)
termed YYR which is specifically exposed on PrPSc. Through optimization of the
length and presentation of this epitope, as well as strategies of formulation
and delivery, we have developed a first generation prion vaccine. This vaccine
was developed with a priority on farmed cervids and employed strategies
compatible with parenteral injection, the traditional route of vaccine delivery.
This vaccine induces high-titre, PrPSc-specific immune responses in a variety of
species and significantly delays the onset of disease in experimentally
challenged sheep. Having validated the DSE immunotherapy concept, we are
positioned to develop a second generation vaccine based upon additional, newly
discovered DSE’s as well as an oral route of delivery. Oral delivery is required
for vaccination of wild animals and is the preferred route for farmed cervids.
Oral delivery may also offer greater protection against oral routes of
infection, which is central to CWD transmission. Funding by PrioNet will enable
and accelerate development of this novel tool to control Chronic Wasting
Disease.
