Pfizer and Valneva Work To Deliver Lyme Disease Vaccine as Bella Hadid Shares Health Journey

American model, Bella Hadid, has shared details of her 15-year battle with Lyme disease. The tick-borne disease is now highly endemic in countries including Finland, Germany, the Netherlands, Poland, Sweden and the United States, and continues to spread. Lyme disease represents a high unmet medical need, impacting the lives of many in the Northern Hemisphere.

There is no vaccine for Lyme disease currently available and the only vaccine previously marketed in the United States, LYMERix®, was discontinued by the manufacturer in 2002, citing insufficient consumer demand.

With new treatments clearly needed, we took a look at the two companies working on developing safe and effective options for preventing and treating Lyme disease:

Pfizer (PFE) and Valneva (VALN)

Industry giant, Pfizer, continues to enroll patients in a Phase 3 study evaluating the efficacy, safety and immunogenicity of a Lyme disease vaccine candidate in conjunction with Valneva.

The study aims to enroll approximately 6,000 participants, 5 years of age and older, from Lyme disease-endemic regions in Europe and the United States. The vaccine candidate, VLA15, is a multivalent, protein subunit vaccine that targets the outer surface protein A (OspA) of Borrelia burgdorferi, the bacteria that cause Lyme disease. This vaccine is designed to protect people against North American and European strains of the Lyme disease bacterium.

The Phase 3 study follows the positive evidence from Phase 2 studies, which demonstrated strong immunogenicity in both adults and children, along with acceptable safety and tolerability profiles.

Pfizer expects to submit a Biologics License Application (BLA) to the FDA and a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) in 2025, pending successful completion of the Phase 3 studies.
