Thermostable vaccine against PPR disease

Reliable, Effective, and Accessible Disease Control for Small Ruminants.

The solution is a homologous live attenuated vaccine that effectively guards small ruminants against Peste des Petits Ruminants (PPR). The vaccine is proven to remain stable at ambient temperatures for extended periods, even withstanding spikes of 38°C for 9 days and 40°C for 7 days.

This technology is TAAT1 validated.

Problem

High Mortality Rates: PPR is a fast-spreading viral disease of sheep and goats with high mortality rates, especially among younger animals.
Limited Vaccine Storage: The requirement for cold storage has limited the widespread use of the current available vaccine within eradication programs.
Economic Losses: Economic losses from PPR across Africa and Asia are estimated to be USD 2.1 billion per year.
Vaccine Stability: Previous constraints included maintaining vaccine stability, especially in areas with limited access to cold storage.
Limited Coverage: The need for cold storage restricted the adequate coverage of vaccination campaigns, limiting the protection of animals.
Outbreak Reporting: PPR is a notifiable disease, necessitating the reporting of outbreaks to national veterinary authorities.
Disease Surveillance: Disease surveillance, including animal movement monitoring and quarantine measures, is crucial for controlling outbreaks and preventing spread.
Biosecurity Measures: Identification of high-risk areas with inadequate biosecurity measures is essential to prevent infection and spread.

Solution

Stability at Ambient Temperatures: Eliminates the need for cold storage for a given number of days, making the vaccine widely accessible and reducing logistical challenges.
Extended Shelf Life: Remains effective for up to one week at ambient temperatures, ensuring vaccines remain potent even in areas with limited refrigeration facilities.
Proven Effectiveness: Demonstrated efficacy during field trials, providing reliable protection against PPR in small ruminants.
Cost-Effective: Reduces storage costs associated with cold chain maintenance, making the vaccine a more affordable solution for farmers.
Improved Coverage: Enables vaccination of a larger number of animals in less time, contributing to more comprehensive disease control efforts.
Lifetime Immunity for Most Animals: Offers long-term protection, reducing mortality rates and economic losses associated with PPR outbreaks.
Compliance with Eradication Efforts: Aligns with international standards set by organizations like the World Organization for Animal Health and the Food and Agriculture Organization, supporting global efforts to eradicate PPR.

Key points to design your business plan

Using Disease Eradication through Thermotolerent PPR Vaccines technology significantly reduces the incidence of PPR outbreaks among small ruminants, thereby enhancing food security and improving livelihoods for farmers.

As essential collaborators, sellers of the product are indispensable. Regarding cost considerations, the vaccine dose typically ranges from 0.3 to 0.5 USD per animal.

Vaccination is recommended for all goats and sheep, irrespective of their production scale. A well-organized vaccinator can administer treatment to up to 5,000 animals monthly, ensuring a business with a satisfactory return on investment.

Animal owners are not obligated to obtain permits but are strongly encouraged or required to ensure all their animals receive treatment.

Adults 18 and over: Positive high

Others: No impact

The poor: Positive low

Under 18: Positive low

Women: Positive medium

Climate adaptability: Highly adaptable

Farmer climate change readiness: Significant improvement

Biodiversity: Positive impact on biodiversity

Environmental health: Moderately improves environmental health

Water use: Same amount of water used

Scaling Readiness describes how complete a technology’s development is and its ability to be scaled. It produces a score that measures a technology’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

Report outbreaks of PPR to national veterinary authorities as PPR is a notifiable disease.
Implement disease surveillance considering animal movement, farm quarantine, and identification of high-risk areas.
Source vaccines from reliable suppliers and ensure proper cold chain management.
Administer vaccines through trained and certified vaccinators, ensuring correct dosage.
Monitor vaccinated animals for signs of immunity and address any concerns promptly.
