Lyme Disease Vaccine Being Developed

BOSTON (CBS) – More and more people are being afflicted by Lyme disease, not only here in New England but around the country. It begs the question, why don’t we have a vaccine to prevent this common tick-borne illness? A human vaccine was introduced in 1998. It was effective but expensive and there was public concern about its safety and sales were low, so it was yanked off the market four years later. Right now there is only a Lyme vaccine for dogs. Fortunately, there is a new vaccine for humans in the pipeline developed by a French company, which says it has received fast-track status from the FDA and hopes to get the vaccine licensed in about five years.

This study assessed cost-effectiveness of a potential anti-tick vaccine that would protect against both Lyme borreliosis (LB) and tick-borne encephalitis (TBE) in a highly endemic setting of Slovenia.A Markov model was developed to estimate cost-effectiveness of a vaccine with potential combined protection against LB and TBE from the societal perspective. The model expressed time in annual cycles, followed a target population through their lifetime, and applied an annual discounting of 3%. A target population entered the model in a susceptible state, with time dependent probabilities to acquire LB/TBE. Disease manifestatio...

The tick-borne pathogen Borrelia burgdorferi is responsible for approximately 300,000 Lyme disease (LD) cases per year in the United States. Recent increases in the number of LD cases, in addition to the spread of the tick vector and a lack of a vaccine, highlight an urgent need for designing and developing an efficacious LD vaccine. Identification of protective epitopes that could be used to develop a second-generation (subunit) vaccine is therefore imperative. Despite the antigenicity of several lipoproteins and integral outer membrane proteins (OMPs) on the B. burgdorferi surface, the spirochetes successfully evade anti...

Abstract Tick-borne encephalitis (TBE) is widely prevalent on the Eurasian continent, including Japan, but four cases of TBE have been reported in Japan. To inspect unconfirmed TBE cases in Japan, we conducted a retrospective seroepidemiological study of a total of 158 samples from 81 meningoencephalitis patients suspected as Lyme disease. Two serum samples from one patient showed neutralizing antibodies against TBE virus. The patient with severe and progressive encephalitis had a history of tick bite in Hokkaido in 2012. These results demonstrated that tick-borne encephalitis virus (TBEV) case was actually unconf...

CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Vectorborne diseases are a large and growing public health problem in the United States, characterized by geographic specificity and frequent pathogen emergence and introduction. Differences in distribution and transmission dynamics of tickborne and mosquitoborne diseases are often rooted in biologic differences of the vectors. To effectively reduce transmission and respond to outbreaks will require major national improvement of surveillance, diagnostics, reporting, and vector control, as well as new tools, including vaccines.

(Natural News) Lyme disease cases are on the rise in the Western world, and pharmaceutical companies are hoping to cash in on the illness with the help of a new vaccine. In the U.S., the number of confirmed cases of the tick-borne illness in 2015 was nearly 29,000, compared to 23,000 ten years earlier. Lyme...

In this study, we evaluated two mouse models - the C3H/N and Balb/c strains for susceptibility to infection and ability to transmit the pathogens via tick vector and to reveal the potential interactions between various bacterial tick-borne agents. Our results indicated that the C3H/N and Balb/c mice are well-accepted models of B. afzelii infection. However, they are not suitable for interaction studies with R. helvetica since the animals did not acquire rickettsiemia and do not transmit Rickettsia sp. to feeding ticks.

We performed a field survey to investigate people’s knowledge, attitudes and practices (KAP) regarding ticks, tick-borne diseases, and prevention strategies. The KAP were assessed using a pre-validated anonymous questionnaire consisting of 39 questions and statements. On two consecutive days in July 2016, conveni...
