NIAID Webpage on Lyme Vaccines

The National Institute of Allergy & Infectious Diseases (NIAID), National Institutes of Health (NIH), has a page on Lyme vaccines including its information on what occurred with the first Lyme vaccine, LYMErix, and what is happening with some current vaccines and vaccine research.


Pfizer Gets Priority Review for Tick-Borne Encephalitis Vaccine

Pfizer has received priority review for their vaccine, TicoVac, which protects against tick-borne encephalitis. This tick-borne virus can cause meningitis and trigger long-term neurological symptoms in humans. If approved, the vaccine would potentially protect travelers and members of the United States military that are deployed to regions where the virus is common, such as Europe and parts of Asia.

TicoVac is an inactivated virus vaccine that has been highly effective at preventing tick-borne encephalitis throughout Europe for four decades. With this FDA fast-pass, it is hoped that a US approval would occur by August and would simplify the process for US military members to get the vaccine. 

Pfizer is also developing a vaccine for another tick-borne illness: Lyme disease.

Phase 2 Study for Lyme Disease Vaccine Candidate Begins

Valneva and Pfizer announced that they have initiated a Phase 2 study for their Lyme disease vaccine candidate. This is currently the only active Lyme disease vaccine in clinical development. 

This new study builds on previous studies, including new dose regimens as well as being the first clinical study to include children between the ages 5-17 years. Advancement to Phase 3 studies will depend on the outcome of this study.

Six serotypes prevalent in both North America and Europe will be covered by this vaccine and the vaccine targets one of the most dominant surface proteins expressed by Borrelia the pathogen when present in a tick, the outer surface protein A (OspA). 

Note: The Lyme Disease Association Inc. has not taken a position on this vaccine but presents current information so consumers take actions relating to any information presented or can make informed decisions on issues presented.

NIH Grants 1.9 Million for Vaccine to Prevent Lyme

Ticks with blades of grass in a jarWest Virginia University researchers received a $1.9 million grant from the National Institute of Allergy and Infectious Diseases, an institution of the National Institute of Health (NIH), for a vaccine to prevent humans from contracting Lyme disease.

Mariette Barbier, assistant professor in the School of Medicine’s Department of Microbiology, Immunology and Cell Biology, is leading the five-year project, along with Timothy Driscoll, assistant professor of biology in the Eberly College of Arts and Sciences, and Heath Damron, assistant professor and director of the WVU Vaccine Development Center.

Barbier and her team will try to develop a vaccine effective against the various species of Borrelia (the Lyme disease bacteria). They will be using RNA sequencing to examine how pathogens respond in both infected ticks and mice, and identify relevant antigens during infection.

Driscoll will be studying the proteins made by Borrelia during the black-legged ticks life cycle. “In vaccine development, what we try to do is identify those proteins and target them in hopes of clearing the pathogen out, killing it, essentially. If a protein is essential for survival, it makes it harder for the pathogen to change it and evade the immune system,” says Driscoll.

Barbier has studied bacterial pathogens, including Pseudomonas aeruginosa, which requires iron to grow and infect their host. “We figured out which antigens could be used to formulate a vaccine, and found the Achilles heel to the bacteria to use against it,” Barbier said. “We focused on one system, which is the iron acquisition system of Pseudomonas.”  Since Borrelia does not require iron, she is driven to find what would be required of Borrelia.

Barbier said. “If it doesn’t use iron, what else can we use against it? By bringing in the expertise of others, we’re going to crack the problem.”

NIH awards $3.5 Million for Novel Lyme Disease Vaccine Study

syringeWith a new $3.5 million grant from the National Institutes of Health (NIH), Utpal Pal, PhD, professor in Veterinary Medicine at the University of Maryland (UMD) will be partnering with Matthias Schnell, director of the Jefferson Vaccine Center at Thomas Jefferson University to develop a novel “next-generation” Lyme disease vaccine.

Pal, a tick immunobiologist, and Schnell, whose lab studies rabies virus as a platform for vaccination, will adapt the rabies virus platform to fight Lyme disease.  The inactivated rabies virus, which helps the body produce antibodies to fight rabies, will be repurposed to produce other types of proteins that can fight Borrelia burgdorferi, the Lyme disease bacteria, a technique found effective for other viral vaccinations. 

This study will test the four already identified vaccine candidate proteins, as well as the three major types of rabies vaccine platforms– using live attenuated virus, inactivated virus, and the shell of a virus with viral proteins on the outside but no virus inside to trick the body.  Pal is also studying both Borrelia proteins and the tick proteins that keep the Borrelia alive so it can be tramsmitted to humans.

Lyme Vaccine Candidate: Valneva Announces Phase 2 Study Results

VLA15 is the only active Lyme disease vaccine candidate in clinical development today, covering six serotypes of Lyme disease prevalent in North America and Europe.  It was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) in July 2017.   In a few months, Valneva expects to report top-line results for the second Phase 2 study, VLA15-202.  Valneva and Pfizer are collaborating for development and commercialization of VLA15.

Lyme Disease Vaccine Collaboration Announced

Press Release Summary
Specialty vaccine company Valneva SE  and Pfizer Inc. announced a collaboration to develop VLA15, Valneva’s Lyme disease vaccine candidate, which is currently in Phase 2 clinical studies.

According to a Pfizer press release, VLA15 is the only active Lyme disease vaccine program in clinical development today. The program covers six serotypes of Lyme disease that are prevalent in North America and Europe.  The vaccine’s mechanism targets the outer surface protein A (OspA) of Borrelia burgdorferi (Bb), the bacteria that causes Lyme disease. OspA is one of the most dominant surface proteins expressed by Bb when present in a tick.

Pfizer states that VLA15 has demonstrated strong immunogenicity and safety data in pre-clinical and Phase 1 studies. In July 2017, the program was granted Fast Track designation by the U.S. Food and Drug Administration (FDA). Valneva expects to report on results from the first Phase 2 studies by mid-2020.

“We look forward to working closely with Valneva to continue advancing the VLA15 program and potentially bring a new solution to patients for this significant unmet need,” said Nanette Cocero, Global President, Pfizer Vaccines.

Comments From the Lyme Disease Association
The Lyme Disease Association President, Pat Smith, had this to say about the announcement:  “A safe and effective vaccine for Lyme disease has been a goal for many decades. Unfortunately, many stakeholders, especially some vaccine recipients and providers who were then giving the vaccine, felt there were problems associated with the past Lyme vaccine, perhaps connected to its Osp A base. There are still many unanswered questions about what really happened, and like much that happens with Lyme disease, decades later, we still do not have those answers.  The prudent thing for the government and/or vaccine developers to have done would have been to hold public meetings regarding a new Lyme vaccine with all interested stakeholders to hear concerns and answer questions about the development of a new Osp A-based vaccine and what research was done to address the previous concerns and any newly arisen concerns.

In general, much research on Lyme disease has still not been done. In fact, ~46 years into Lyme disease, it ranks below leprosy in the number of clinical trials done in infectious diseases (Goswami et al., 2013).  Those who have questioned the safety and efficacy and approval process of the past vaccine have been publicly accused of bringing that vaccine down.  When the opportunity for dialogue which engages the Lyme community and all stakeholders has not been offered as part of the approval process, it creates an atmosphere of distrust among those whose trust is necessary to accept a new Lyme disease vaccine.”

New Lyme Vaccine in Clinical Trials: Update!

syringeAn article on a new vaccine for Lyme disease, “New Effort for Lyme Disease Vaccine Draws Early Fire,” by Sumathi Reddy, appeared in the Wall Street Journal on July 9, 2018. The article, which includes a quote by LDA President, Pat Smith, reports that a European company, Valneva SE, is in clinical trials for a vaccine for Lyme disease, which has been fast tracked by the FDA. (see 4/28/19 update at end of article)

A company official estimates it will take at least five years before it becomes commercially available. The vaccine is similar to Lymerix, by Smith Klein Beecham (SKB), now GlaxoSmithKline, which was approved by the Food and Drug Administration (FDA) in December 1998 but was withdrawn from the market in 2002 due to low demand.

“We don’t feel that there has been enough research done to answer the questions as to what occurred with the prior vaccine,” says Patricia Smith, president of the Lyme Disease Association Inc., a New Jersey-based national nonprofit group, which raises money for Lyme research, education and patient support. “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.”

Check out the history of Lymerix and efforts by the LDA and others to get the facts behind the vaccine and its withdrawal– individuals who took the vaccine who spoke at the FDA on the problems they felt were related to the vaccine; class-action lawsuits that alleged it caused serious side effects; and a meeting requested by LDA at the FDA where LDA brought in a vaccine expert and physicians who were seeing patients with problems they felt were connected to receiving the vaccine.

Update on Lyme vaccine 4-28-19  On July 2017, Valneva received from the Food & Drug Administration (FDA) a Fast Track Designation for VLA15. On April 4, 2018, Valneva presented Phase 1 interim results of the vaccine at the World Vaccine Congress in DC. In December of 2018, Valneva announced the initiation of Phase 2 Clinical Trial Development to determine the optimal dosage level and schedule for use in Phase 3 field efficacy studies, based on immunogenicity & safety data.
