MaineHealth is taking part in a analysis trial this is checking out the effectiveness of a possible new Lyme vaccine that might save you hundreds of circumstances of the illness every yr in Maine if authorized by means of federal regulators.
Dr. Robert Smith, director of the MaineHealth Institute for Analysis’s Vector-Borne Illness Lab in Scarborough, stated the vaccine is appearing promise that it’s going to save you Lyme illness. If confirmed secure and efficient, it may well be able for public rollout in two to a few years.

Maine set a report for Lyme infections in 2023, with 2,943 reported circumstances of the illness, and the state has noticed a gradual upward thrust in circumstances over the last decade. Lyme illness is transmitted to people by means of the deer tick, and signs come with a fever, headache, fatigue, joint ache, muscle aches and pains, and swollen lymph nodes. The indicators frequently come with a bulls-eye rash on the web page of the tick chunk however the rash isn’t all the time provide.
If stuck early, Lyme may also be handled with a process antibiotics. However some folks revel in continual signs lengthy after the an infection has run its path.
Scientists were operating for years to stop the illness thru a secure vaccine.

“The early knowledge is encouraging,” Smith stated. “I’m hopeful that it’s going to actually assist in protective folks from Lyme illness.”
At MaineHealth’s Pen Bay Scientific Heart in Rockport, 84 sufferers had been enrolled in Pfizer’s scientific analysis trial in 2023, with part receiving the Lyme vaccine and the opposite part getting a placebo. The vaccine trial enrolled 9,000 sufferers in america, Europe and Canada.
Those that were given the vaccine or a placebo can be monitored for Lyme illness thru December 2025, and effects from the scientific trial will get started changing into to be had in 2026. One after the other, some other attainable Lyme vaccine being advanced by means of Valneva is also present process scientific trials, the U.S. Facilities for Illness Regulate and Prevention stated.
If a success, the brand new drug will be the first Lyme vaccine to be had to be used in people since a prior Lyme vaccine was once pulled off the marketplace in 2002, despite the fact that a vaccine for canines stays to be had.

“It feels just right to be a part of serving to to deliver this to fruition,” stated Caroline Knight, a registered nurse and analysis coordinator at Pen Bay. “Optimistically, we will all be vaccinated identical to our canines are.”
There have been various causes the former human vaccine was once got rid of from the marketplace, Smith stated, together with incorrect information that the vaccine led to Lyme illness, and that the illness had now not reached the top collection of circumstances now being reported, particularly within the Northeast.
Knight stated the brand new vaccine will be more practical than the former one, which was once best available on the market for a couple of years beginning within the overdue Nineties.
RESEARCH ON OTHER TICK-BORNE DISEASES
The Lyme vaccine would now not offer protection to in opposition to different commonplace tick-borne sicknesses, equivalent to anaplasmosis and babesiosis. There have been 777 circumstances of anaplasmosis in Maine in 2023, and 194 circumstances of babesiosis.
MaineHealth is also taking part in analysis that might see a extra correct blood check that might stumble on the presence of the Lyme micro organism, Borrelia burgdorferi. And some other analysis find out about would attempt to decide the blood meal supply of ticks inflamed with Powassan virus. Just a handful of circumstances are reported in Maine every yr, and scientists are nonetheless studying about it and its attainable, however Powassan virus may cause critical illness, together with an infection of the mind (encephalitis) or the membranes across the mind and spinal twine (meningitis), the CDC says.
Rebecca Robich, a analysis scientist at MaineHealth, stated professionals in the beginning believed the Powassan virus was once transmitted by means of ticks discovered on white-footed mice, however the proof is to this point now not supporting that idea. So Robich stated a crew of researchers this summer season in Maine can be checking out ticks that raise the Powassan virus to peer what animal they had been prior to now connected to, together with shrews, mice, voles, birds, deer, canines and cats.
