In the last fifteen years, concern over tick-borne diseases
has begun to over shadow the enjoyment of recreational summer activities. The
ticks that carry Lyme disease can be found in grassy areas like lawns, shrubs
and woodlands.
Lyme disease in particular has become so wide spread in the
United States that it is the number one vector borne illness. Public health
experts are most concerned about children and adults who work or spend a lot of
time outside and are urging the development of a Lyme vaccine.
“The fact that there is no vaccine for an infection causing
some 20,000 annual cases of Lyme is an egregious failure of public health,”
states emeritus professor of medicine Stanley A. Plotkin of the University of Pennsylvania.
Baxter International is currently developing a Lyme vaccine,
but is moving slowly because of backlash earlier Lyme vaccines had from
anti-vaccine groups. The Food and Drug Administration approved two Lyme
vaccines in the 1990s, although only one of them made it to the market.
Lymerix was put on the market in 1998, but false claims were
made that Lymerix caused arthritis. Anti-vaccine groups went so far as to claim
that Lymerix caused Lyme disease. Although the claim was later proved wrong,
the vaccine was pulled from the market in 2002 because of a class action
lawsuit based on the false claims and declining sales.
Lorraine Johnson is the chief executive of LymeDisease.org,
an advocacy group and states: “I’m cautious about vaccines. Everyone wants a
good vaccine, but no one wants a vaccine that enriches researchers and harms
patients like the last one.”
Meanwhile, a group at the University of Rhode Island (URI)
is working to develop another vaccine. The group is using the protein from deer
tick saliva to create the vaccine. After being vaccinated, anyone who is bit by
a tick will have an itching sensation and their body’s immune system will be
triggered to attack any pathogens the tick delivers.
With this previous history in mind, Baxter International and
the group at URI continue to develop vaccines to combat this terrible disease.
Their goal is to explain that the vaccine is safe and effective and will not
cause Lyme disease, while helping thousands of people avoid this debilitating
disease. Vaccine Watch encourages people to learn more about vaccines and speak
with their doctors – especially if a vaccine has the potential to combat a
terrible disease.
