Newcastle Disease Vaccine
Thermostable Newcastle disease protection for smallholder and commercial poultry programmes across Africa.
Newcastle disease kills 20-80% of unvaccinated village poultry flocks. For smallholder households, that is their primary income source.
Newcastle disease kills 20-80% of unvaccinated birds within two weeks of introduction, making it the most devastating disease affecting poultry in sub-Saharan Africa. Zoetis thermostable La Sota and HB1 vaccines can be given by eye drop, drinking water or spray at any scale from a village flock to a commercial shed. Jos•Hansen supplies Zoetis ND vaccines to government campaigns, agribusinesses and veterinary distributors across East Africa.
Thermostable
Zoetis thermostable ND vaccine retains potency for defined periods at ambient temperatures above 2-8°C. That is the critical performance characteristic for rural poultry programmes where uninterrupted cold chain to the village level cannot be guaranteed.
Three delivery routes
Eye drop, drinking water or spray administration enables flexible delivery at any scale. A single smallholder's 50-bird flock is vaccinated by eye drop. A commercial 50,000-bird shed is vaccinated by spray in a single pass.
Broad NDV coverage
La Sota and HB1 strains provide broad-spectrum protection against virulent velogenic and mesogenic Newcastle disease strains, the genotypes responsible for outbreak mortality in East African poultry populations.
An ND outbreak in unvaccinated flocks is a total loss.
Virulent Newcastle disease kills 20-80% of an unvaccinated flock within 7-14 days. For smallholder households in rural East Africa, where poultry are the most liquid household asset, a single NDV outbreak can erase months of income. ND spreads by airborne aerosol, making containment without pre-existing immunity almost impossible once an outbreak is underway. Vaccination before first exposure is the only viable strategy.
Thermostable La Sota reaches the rural last mile.
Conventional live NDV vaccines require unbroken 2-8°C cold chain from manufacture to inoculation, a standard impossible to maintain across the rural last mile in East Africa. Zoetis thermostable ND vaccine retains protective titre under validated short ambient excursions, making it the formulation of choice for government mass campaigns reaching village poultry through agro-dealer networks. A single vaccination team can process hundreds of birds per hour with a dropper bottle.
Jos•Hansen supports government campaigns and commercial programmes.
For government veterinary departments, Jos•Hansen designs ND mass vaccination campaigns with coverage mapping by ward, cold box allocation, team scheduling and post-campaign serology. For commercial poultry producers, we build vaccination schedules combining ND with IB, IBD and Marek's disease vaccines, aligned to flock age, production type and biosecurity level.

Why Newcastle.
Thermostable formulation
Validated ambient-excursion tolerance makes this vaccine deployable through agro-dealer networks where unbroken cold chain to the village level is not achievable.
Mass campaign deployment
Eye drop and drinking water routes enable a two-person team to vaccinate hundreds of birds per hour, practical for district-level mass campaigns.
Broad NDV strain coverage
La Sota and HB1 strains protect against virulent velogenic and mesogenic NDV genotypes circulating across East Africa.
Programme and schedule design
Jos•Hansen designs ND vaccination schedules for commercial flocks and government mass campaigns, including serology monitoring to verify seroconversion.
