Another Shot at a Vaccine for Lyme Disease

Another Shot at a Vaccine for Lyme Disease

The U.S. National Institutes of Health (NIH) has provided the University of Maryland with a $3.5 million dollar grant to develop a vaccine for Lyme disease.1 Principal investigators Utal Pal, PhD, professor at the Virginia-Maryland College of Veterinary Medicine at the University of Maryland College of Agriculture and Natural Resources and Matthias Schnell, PhD, director of Thomas Jefferson University’s Jefferson Vaccine Center will collaborate on development of the novel Lyme vaccine.

Dr. Pal has identified Lyme vaccine candidate proteins and the rabies vaccine will be used as a delivery platform, although the rabies vaccine has never before been used as a vehicle for a tick born infection vaccine.2 The testing will combine the four candidate proteins Dr. Pal identified as vaccine candidates and three types of rabies vaccine platforms. According to Dr. Pal;

The best adjuvants aren’t safe for humans, but the use of a virus platform eliminates the need for an adjuvant. We are using the virus’ ability to produce a strong immune response to supply the Borrelia proteins and produce the appropriate antibodies.3

The novel research will look at targeting Borrelia proteins, BB0405 and BB139 as well as two parts of tick proteins which deliver the bacteria from tick to human. The plan is to test the best candidates on mice in the future.4

A Yearly “Antibody” Shot for Lyme Disease in the Works

There are researchers at other universities developing alternative ways to prevent Lyme disease. In an attempt to thwart Lyme disease prophylactically without using a traditional type of vaccine, researchers at University of Massachusetts Medical School Mass Biologics are working on an antibody shot called LymePrEP that would delivery an anti-Lyme antibody to the recipient. Unlike a vaccine that triggers the immune system to make antibodies, LymePrep would use a human antibody to kill the bacteria in the tick before it invaded a human host.5

The shot would use pre-exposure prophylaxis to prevent Borellia Burgdorfei, the bacteria that causes Lyme disease, from taking hold in the recipient after a tick bite. It would need to be given on a yearly basis as initial testing in mice showed efficacy lasting for only for several weeks.6 7 Phase 1 clinical trials on people who have not been exposed to Lyme disease are scheduled to be completed in 2022.8

VLA-15 Lyme Vaccine Completes Phase 2 Trials

VLA-15, another potential candidate for a Lyme disease vaccine is currently in phase 2 trials. The vaccine is being developed and marketed by pharmaceutical companies Valneva SE of France and Pfizer, Inc. of New York City, New York.9

VLA-15 vaccine targets OspA, the outer surface and most dominant protein expressed by Borrelia bacteria and is the only current vaccine for Lyme disease in clinical development.10 In July 2017, the U.S. Food and Drug Administration (FDA) granted the VLA-15 Lyme vaccine Fast Track designation.11 Vaccine manufactures that receive a fast track designation may submit less data to the FDA prior to licensing and can conduct clinical studies after the vaccine is licensed and marketed.12

Fast Track designation is granted by the FDA to products that are under development for serious conditions and have the potential to fulfill an unmet medical need. It is designed to facilitate the clinical development and expedite the review of new drugs and vaccines with the intention to accelerate the availability of promising products on the market.13

The initial Phase 2 study included 572 healthy adults ages 18-65. After the safety data was reviewed by an independent data safety monitoring board and declared positive, the main phase study commenced.  In the main phase study, 180 subjects received a lower dose(135 µg) and 180 subjects received a higher dose (180 µg) of the vaccine with an aluminum adjuvant in three shots on days one, 29 and 57, while 90 subjects received a placebo.14

There were no serious adverse events reported.15 In October 2020, Valneva released initial results from its second phase II study claiming that,

 the shot was generally safe across all doses and age groups tested, with the tolerability profile including fever rates being comparable to other lapidated recombinant vaccines or lipid containing formulations.16

Immunogenicity was measured by determining IgG antibodies against each of the six most prevalent OspA serotypes of Lyme bacteria covered in the vaccine. The endpoint readout was determined one month after the last shot, on day 85.17

Immune response was also assessed by looking at the Bactericidal Assay (SBA), which showed a functional immune response against all OspA serotypes.18

The higher doses used in Phase 2 invoked a higher antibody response than the lower doses used in phase 1 of the trials.19 Seroconversion rates were 81.5 to 95.8 percent in individuals receiving the highest doses.20 Looking at the same age group used in Phase 1 of the trials (18-49), the seroconversion rate was 85.6-97 percent.21

Prior exposure to Lyme disease didn’t appear to alter the immunogenicity or safety of the vaccine as seen in both phases of the trials.22

Global Market for a Lyme Vaccine Estimated at Just Under 100 Million Dollars a Year

The global market for a Lyme disease vaccine is estimated at approximately 700 to 800 million euros or 840 to 950 million US dollars annually.23

According to the agreement between Valneva and Pfizer for development and manufacturing of the VLA-15 Lyme vaccine, Valneva could receive a total of $308 million cash payments including $130 million paid upfront, $35 million in development milestones and $143 million in early commercialization milestones. Valneva is responsible for 30 percent of all development costs during the development program and will receive tiered royalties starting at 19 percent from Pfizer, which will be in charge of the late-stage development and be in complete control of commercialization of the vaccine.24

VLA-15 Lyme vaccine is intended to be used in children and adults. While the vaccine candidate has not yet been tested on children, trials are planned for children ages five years of age and above and may eventually include children even younger than five.25

The Murky History of a Lyme Disease Vaccine

Many are skeptical about the development of another vaccine for Lyme disease. VLA-15 vaccine targets OspA, similar to the last Lyme disease vaccine, LYMErix,26 which was reported to cause adverse reactions such as symptoms of Lyme disease, permanent damage to the brain and immune system and treatment resistant autoimmune arthritis.27

According to Medalerts, there were 2,225 adverse events reported to the federal Vaccine Adverse Events Reporting System (VAERS) with 460 of those events considered serious and 49 life threatening after receipt of the LYMErix vaccine.28

The true number of people who suffered serious adverse events following receipt of LYMErix vaccine is likely much higher. In a 2011 report to the U.S. Department of Health and Human Services (HHS), Harvard Pilgrim Healthcare found that less than one percent of all adverse events after receipt of any type of vaccine were reported to VAERS.29

Genetic Predisposition to LYMErix Vaccine Reactions

LYMErix was approved by the FDA in December 1998 and was withdrawn from the market approximately three years later in February 2002.30 In 1999, a study which included one of the lead researchers of the LYMErix vaccine found that OspA which was the base of the LYMErix vaccine could cross-react with a human protein in approximately 20-30 percent of the population who are positive for the HLA-DR4 gene causing complex autoimmune reactions.31 32

Patricia Smith, president of the Lyme Disease Association stated,

 We don’t feel that there has been enough research done to answer the questions as to what occurred with the prior vaccine. The vaccine that is now in development is something with the same base. There were a lot of patients that thought they were harmed from that vaccine. It’s very problematic.”33

After heavily marketing the vaccine with print and broadcast advertisements, LYMErix was discontinued in 2002 due low demand, according to a GlaxoSmithKline spokesman.34 35

Despite the cautionary tale of the previous Lyme vaccine associated with severe reactions and long term damage, the search for a Lyme disease vaccine continues.

    We already have a safe and effective prophylaxis for Lyme disease. It’s called Lyme Nosode, a homepathic remedy that works just fine and has no safety issues. Too bad the FDA is intent on quashing homeopathy in the U.S.

      I’ll have to look for that. Before we were using minced raw garlic for a month, taking it two times a day, every 12 hours. We never ever had these miniscule ticks before that are everywhere now, probably dropping them from planes…. : /

    So, let’s get this straight: the same corrupt health system that has been denying the seriousness and prevalence and persistence of Lyme disease, has attacked treating physicians and their patients ruthlessly, and which has no f-ing understanding whatsoever of the complexity and consequences of tick borne illness because they have deliberately turned their back on the science and experience of ethical researchers and Lyme doctors – this same system has now decided that (in order to make hundreds of millions of dollars), Lyme disease is serious after all – so much so that we had better fast track the research and give it to everyone 5 and over.

    (I also loved seeing the irony of the vaccine researcher calmly stating that the shot will use other pathogens to stimulate an immune response because adjuvants can be dangerous for humans. Well, no kidding!)

      Wait, they’re actually admitting their adjuvants are dangerous?? Gee, but Paul Offit said we can take a kajillion vaccines with no bad outcomes….of course he owns vaccine patents, but I guess that’s OK.

    ‘The best adjuvants aren’t safe for humans, but the use of a virus platform eliminates the need for an adjuvant.’

    AND THERE WE HAVE IT!! Right from the horses mouths…….the people that create the vaccines, have known for ages and ages just the adjuvants are NOT SAFE. But you use Adjuvants for EVERY SINGLE VACCINE.

    So what you are out right saying are vaccines are dangerous and YOU KNOW IT.

    Just to think, this is just the adjuvant, what about all of the rest of the ingredients, surely if the adjuvant is dangerous just imagine what it does when its mixed with all the other crap that is in it.

    Where on Earth will they find someone who has not been exposed to Lyme? It has been in the chemtrails so many times and it is in the chemtrails that are being dropped right now (1!-17-20) and for the past several weeks . It has been close to 20 years that I could find Lyme in everybody using muscle testing. Just look in the macrophages of the spleen before you assume it is not there, and even if you can’t find it, assume it is probably being obscured from detection by something more serious or widely present. I once heard a famous Lyme literate MD say, when asked what proportion of the population he thought was infected with Lyme, answer that it was more like who was symptomatic rather than who was infected. I like peppermint, lime and cassia cinnamon essential oils together against Lyme, though this is a simplistic and incomplete formula. People experienced with Lyme know if they start killing a bunch of Borellia spirochetes they will get sicker with “Herxheimer” reactions.
    As for a “rabies platform”? That sounds ominous. Will someone please clarify and detail that for me?

      So they’ll use rabies to infect people…I mean “inject people” with lyme ‘antibodies’. Sounds like they’re doing some franken-vaccine research to me.

      We used raw minced (organic) garlic, taken 2 times a day every 12 hours. I use at least 1 clove per dose. We took it every day for a month. Seems to clear it up, but someone was talking about homeopathic ‘lyme nosodes’ which would probably not hurt either!

    Wait wait. The article said the vaccine is being developed against “Borellia Burgdorfei”.<<<copied and pasted from the article. Isn't it Borrelia Burgdoferi? They fooled me above, Because my instinct is always to spell it wrong, I looked in the article to check myself and mistakenly spelled it like they did. I keep forgetting to be paranoid enough.

    While yes after the last absolutely terrifying and sketchy Lyme vaccine I am not exactly advocating in any way for one BUT this news is very exciting! It’s opening the doors to more study in Lyme disease and money and shedding light in any form really and that is very good for the lymie community!! This brings me hope that along with a vaccine they will finally actually make an update to the absolute joke that is the current CDC ‘Lyme disease test’

      Last thing we need is more “supposed” solutions from pharma. I cured my Lyme in 8 weeks by following Anthony William “Medical Medium” protocols for Lyme disease – fresh celery juice, his detox smoothie recipe, and several other anti-viral supplements each day. Significant improvement in symptoms in 2-3 weeks and 100% gone in 8 weeks. Check out his website and books. His protocols work for this and many other mystery illnesses! My sister cured her asthma using MM protocols. Many other stories like this from his followers.
