CEO Comments

Strangvac has the potential to fundamentally transform the transmission dynamics and consequences of strangles.

I am very pleased to join the Intervacc team at this important stage of the company’s journey. Under Jonas Sohlman’s leadership, Strangvac has been launched in 16 European countries, and we are now beginning to see growth gaining momentum. I look forward to contributing my broad experience in pharmaceutical development, business operations and the capital markets to build on these achievements.

Strangvac has the potential to fundamentally transform the transmission dynamics and consequences of strangles. Intervacc’s strong platform has generated a vaccine which, following a booster dose, has been shown to provide over 90% protection. Instead of severe infections with abscess formation in the head and neck – and with up to 10% mortality among affected horses – the vast majority of vaccinated animals experience mild or no clinical signs.

Strangvac offers unique advantages for protecting horses against strangles, but breaking established routines and implementing change takes time. To strengthen the company’s commercial performance, Anna-Carin Lagerlöf – with many years of experience in veterinary sales – was recruited in the fourth quarter as director of Sales and Marketing Director.

The safety study involving 600 horses in the United States began during the fourth quarter and is expected to be completed in 2026. This will be followed by an efficacy study, which is planned to commence in the latter part of 2026, with completion anticipated in 2027. These studies are important milestones for obtaining regulatory approval in the United States and thereby gaining access to a market comprising 10 million horses.

Two important scientific articles were published during the quarter. They demonstrated that vaccinating horses with Strangvac during strangles outbreaks, or when an infected horse has entered a stable, is both safe and protective. This highlights the vaccine’s effectiveness even in acute situations where infection is present or suspected after the arrival of a new horse. The positive field experience has led experts in both the UK and Sweden to begin preparing national recommendations that vaccination against strangles should form part of a modern biosecurity programme. As veterinarians and horse owners gain more experience with Strangvac, further publications and guidelines are expected to advocate for its use and its inclusion alongside the existing influenza vaccination schedule every six to twelve months.

Intervacc’s most important pipeline project – a vaccine to protect newborn piglets against the serious pathogen S. suis – is in early development, with efficacy studies underway against different serotypes. There is currently no approved vaccine for S. suis, and the infections cost the pig industry approximately EUR 250 million annually in Europe alone.

The company has only just begun its journey to globally transform the protection of horses against the feared disease strangles. As with all early-stage biotechnology companies, production entails significant financial volatility. During the fourth quarter, a write-down of nearly SEK 18 million was made relating to manufactured material. While this affects the reported result, it has no cash impact.

We look forward to continuing the market introduction of Strangvac, documenting all of its benefits, completing the regulatory process in the United States, and launching Strangvac on the US market. Strangvac is a remarkable product, and I want to thank Intervacc’s shareholders and other stakeholders for enabling our efforts to minimise the impact of strangles on equine health.
