A New Vaccine Candidate
However, in July 2017, the Food and Drug Administration granted fast-track designation to a new Lyme disease vaccine candidate called VLA15. Fast-track designation means that the review of the vaccine will be expedited, with an eye toward earlier availability to the general public. This vaccine was fast-tracked to fight the rapidly growing problem of Lyme disease, which can result in considerable disability and long-term suffering in some.
VLA15 is a multivalent vaccine, which means that it confers protection against more than one strain of Borrelia, the bacteria that causes Lyme disease. More specifically, VLA15 targets outer surface protein A , which is the most dominant protein in Borrelia transferred by ticks. Because it targets six different types of OspArepresenting six different strains of Borreliathis vaccine has the potential to protect against Lyme disease spread in the United States, Europe, and worldwide.
In light of the vaccines fast-track designation, Valneva, the company that manufactures VLA15, has stepped up phase II clinical trials. According to a July 2017 press release, phase I clinical trials involve 180 participants from three sites, two in the United States and one in Belgium.
Lyme Disease Signs And Symptoms
Most symptoms of Lyme disease in humans usually appear between three and 30 days after a bite from an infected blacklegged tick.
You should contact your local public health unit or speak to a health care professional right away if you have been somewhere that ticks might live and experience any of the following symptoms:
- a bulls-eye rash (a red patch on the skin that is usually round or oval and more than 5 cm that spreads outwards and is getting bigger
- a bruise-like rash
- another type of unusual rash
- muscle aches and joint pains
- swollen lymph nodes
- spasms, numbness or tingling
- facial paralysis
If not treated, Lyme disease can make you feel tired and weak and, if it gets really bad, it can even harm your heart, nerves, liver and joints. Symptoms from untreated Lyme disease can last years and include recurring arthritis and neurological problems, numbness, paralysis and, in very rare cases, death.
Early Detection Is Key
Stephen Morse, PhD, an epidemiologist at the Columbia University Mailman School of Public Health, said that the findings were reassuring.
The general wisdom about it was even if you didnt find the tick immediately it would take about 48 hours, to contract Lyme disease, said Morse. This seems to be true here, too.
Morse said the data can help to inform people on how to enjoy the outdoors safely.
He pointed out that in areas with high numbers of ticks, people may need to take precautions even if they just go into their own backyards.
If youve got a nice backyard, use that mosquito repellent or bug repellent, he said.
In addition, there are obviously the usual precautions of dont leave a lot of exposed skin, and be careful if youre climbing the underbrush.

Protect Yourself From Tick Bites
Know where to expect ticks. Blacklegged ticks live in moist and humid environments, particularly in and near wooded or grassy areas. You may get a tick on you during outdoor activities around your home or when walking through leaves and bushes. To avoid ticks, walk in the center of trails and avoid walking through tall bushes or other vegetation.
Repel ticks on skin and clothing. Use Environmental Protection Agency -registered insect repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone. EPAs helpful search tool can help you find the product that best suits your needs. Always follow product instructions.

Symptoms Of Lyme Disease
A circular or oval shape rash around a tick bite can be an early symptom of Lyme disease in some people.
The rash can appear up to 3 months after being bitten by an infected tick, but usually appears within 1 to 4 weeks. It can last for several weeks.
The rash can have a darker or lighter area in the centre and might gradually spread. It’s not usually hot or itchy.
The rash may be flat, or slightly raised, and look pink, red, or purple when it appears on white skin. It can be harder to see the rash on brown and black skin and it may look like a bruise.
Some people also get flu-like symptoms a few days or weeks after they were bitten by an infected tick, such as:
- a high temperature, or feeling hot and shivery
- tiredness and loss of energy
Some people with Lyme disease develop more severe symptoms months or years later.
This is more likely if treatment is delayed.
These more severe symptoms may include:
- pain and swelling in joints
- nerve problems such as pain or numbness
- heart problems
- trouble with memory or concentration
How Can I Prevent Lyme Disease
- Avoid tick-infested areas, particularly in May, June, and July.

How Can You Prevent Lyme Disease
The best way to protect against Lyme disease is to prevent tick bites. Check the detailed risk areas map to find out where infected ticks are most likely to be found. Remember, as tick populations spread, the risk of acquiring Lyme disease will occur outside these areas in the future. Ticks can be dispersed out of these areas by migratory birds so there is a low risk of being bitten by a tick outside of the known risk areas.
It is recommended that Canadians travelling to highly Lyme endemic areas of the US and Europe, apply permethrin treatments to their clothing or use clothing pre-treated with permethrin. These products can be obtained in some travel clinics or from outdoors retailers when in the US.
Ticks can be infected with more than one type of bacteria that can cause human illness. Guarding against tick bites will protect you from more than just Lyme disease.

Be Tick Aware
Practicing good tick bite prevention habits is the best way to prevent Lyme disease and other tick-
borne illnesses. Good habits range from what clothing you wear, where you walk, and how often you check for ticks. Simply, its important to Be Tick AWARE.
AVOID areas where ticks live. Ticks thrive in wood piles, leaf litter, long grass, beach grass, bushy areas, stone walls, and perimeters where the lawn meets the woods.
WEAR light-colored clothing to spot ticks more easily long-sleeved shirt tucked in at the waist, long pants tucked into high socks, closed-toe shoes, and a hat with your hair tucked in, if possible. Do not walk in the grass barefoot or in open sandals, even if its cut short.
APPLY EPS-approved tick repellent and insecticide to skin, clothing, and shoes as directed.
REMOVE clothing upon entering the home toss into the dryer at high temperature for 10-15 minutes to kill live ticks. Putting them in the washer, however, will not.
EXAMINE yourself and your pets for ticks daily. Feel for bumps paying close attention to the back of knees, groin, armpits, in and behind the ears, belly button, and scalp. Check everywhere ticks love to hide! Shower or bathe as soon as possible to wash away unattached ticks. If you find a tick, remove it quick!

How Do Ticks Get On You
When it comes to letting you know that youre being bitten, ticks are a little stealthier. They can get in underneath your clothing and start to feed, and you may not even know that youre being bitten.
What they do is they questing. Ticks actually will sit on vegetation and put their front legs out and wait for something to come by, and they latch on.
Ticks dont drop from trees. They dont jump either, so if you find a tick in your hair, it must have gotten there two ways.
Firstly is it crawled up there, or you placed it there. You had it on your hand, and you scratched your head, and when you placed it there.
The second way they get up there is when youre rolling around in the grass.
What Causes Lyme Disease
Lyme disease is caused by bacteria. In the United States, this is usually a bacterium called Borrelia burgdorferi. It spreads to humans through the bite of an infected tick. The ticks that spread it are blacklegged ticks . They are usually found in the:
- Upper Midwest
- Pacific coast, especially northern California
These ticks can attach to any part your body. But they are often found in hard-to-see areas such as your groin, armpits, and scalp. Usually the tick must be attached to you for 36 to 48 hours or more to spread the bacterium to you.
