What is the history of Lyme disease?

Clinicians first recognized Lyme disease in the United States in 1977 when a cluster of juvenile ‘rheumatoid arthritis’ cases occurred in Lyme, Connecticut. Researchers identified the source of the cluster of cases as a tick-borne infection rather than an autoimmune disease.

How many Lyme shots were given in 2001?

By 2001, with over 1·4 million Lyme vaccine doses distributed in the United States the VAERS database included 905 reports of mild self-limited reactions and 59 reports of arthritis associated with vaccination [29]. The arthritis incidence in the patients receiving Lyme vaccine occurred at the same rate as the background in unvaccinated individuals. In addition, the data did not show a temporal spike in arthritis diagnoses after the second and third vaccine dose expected for an immune-mediated phenomenon. The FDA found no suggestion that the Lyme vaccine caused harm to its recipients.

How do people get Lyme disease?

People living in endemic areas acquire Lyme disease from the bite of an infected tick. This infection, when diagnosed and treated early in its course, usually responds well to antibiotic therapy. A minority of patients develops more serious disease, particularly after a delay in diagnosis or therapy, and sometimes chronic neurological, cardiac, …

What lessons have been learned from Lymerix?

In the aftermath of the LYMErix? market withdrawal, we must look for lessons learned. The vaccine developers believed they developed a safe and effective vaccine to prevent the most common tick-borne infection in the United States. Even available post-market surveillance failed to demonstrate convincing harm from the LYMErix? vaccine. After review of available data, the FDA found insufficient evidence to support a causal relationship between the reported adverse effects and the vaccine and continued to permit use of the vaccine. However, the public’s perception of potential risks, heavily influenced by the negative press coverage and limited awareness of the benefits of the vaccine, decreased consumer demand for the vaccine.

When did Lymerix drop?

Spawned by the press coverage of vaccine risks and the ongoing litigation, vaccine sales fell off dramatically in 2001. On 26 February 2002 GlaxoSmithKline decided to withdraw LYMErix? from the market citing poor market performance [37].

What is risk communication?

Risk communication represents the process of informing individual and collective decision-making by describing benefits as well as risks. As illustrated by the case of Lyme vaccine, the issues involved often become very complex and require an in-depth understanding to accurately access risk. However, the public attention span is typically short. The media often serve as the only channel through which the general public obtains its health information.

What is the cause of the cluster of cases?

Researchers identified the source of the cluster of cases as a tick-borne infection rather than an autoimmune disease. By 1983, investigators identified the causative agent, a previously unrecognized spirochetal bacteria called Borrelia burgdorferi[1, 2].

What is the best way to prevent lyme disease?

The increased market for a Lyme preventive has prompted action from pharmaceutical companies. There are two options for preventing Lyme in the works: one vaccine that works the same way LYMErix did; and one shot that would be taken annually, in advance of tick season (technically a preexposure prophylaxis, or PrEP, shot). The vaccine is a collaboration between Valneva (a French biotech company) and Pfizer and has already shown promising results in Phase 2 trials. In March, the companies announced that their candidate was going into an additional Phase 2 study that would include a pediatric population of kids over age 5. (LYMErix was never approved for kids under 15—another factor in the low demand for the shot.) Pfizer and Valneva hope for their vaccine to be available by 2025.

How does Lymerix work?

LYMErix worked by inducing antibodies into human blood, which would then go into any ticks that attached to your body. There, they would neutralize the bacteria that cause Lyme, Borrelia burgdorferi, before the bacteria could go from the tick into you.

Why don’t we have a lyme?

This is how I have seen it explained, in shorthand form: We don’t have a Lyme vaccine because of anti-vaxxers. Retelling the LYMErix story in 2018, Vox’s Brian Resnick described it as “a stark reminder of how anti-vaccine mania of the past few decades is leaving us all more susceptible to disease.”.

What was Lymerix’s downfall?

Advertisement. The story of LYMErix’s downfall has become a case study in the history of vaccines, in part because of its complexity. In his book on the Cutter Incident —a disastrous episode in the mass distribution of the Salk polio vaccine—and its impact on vaccine production, vaccine historian Paul Offit described what happened …

Is Lymerix a cushion?

Because of that exemption from the federal program, writes Offit, there was no cushion between the manufacturers of LYMErix and anyone who might claim it caused their arthritis. The vaccine “was left to survive the abuses of personal injury lawyers and the inaccurate media reports that inevitably follow.”. Advertisement.

Was Lymerix a failure?

The failure of LYMErix was not just about “anti-vaxxers,” broadly painted, but about a very specific brew of hesitancy—which, at least in part, was fueled by a general unawareness of Lyme. It’s also true that there was just less need for the vaccine.

Is Valneva a Pfizer?

The vaccine is a collaboration between Valneva (a French biotech company) and Pfizer and has already shown promising results in Phase 2 trials. In March, the companies announced that their candidate was going into an additional Phase 2 study that would include a pediatric population of kids over age 5.
