PPR Vaccines Disease Eradication through Thermostable PPR Vaccines

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

The vaccine is a homologous live attenuated solution that effectively guards small ruminants against PPR. It comes in two variants: the ILRI thermotolerant PPR vaccine produced through the Thermovac process, and Xerovac, an established option. Both are proven to remain stable at ambient temperatures for extended periods, even withstanding spikes of 40°C.

This technology is TAAT1 validated.

Problem

High Mortality Rates: PPR is a fast-spreading viral disease with high mortality rates, especially among younger animals.
Limited Vaccine Storage: The requirement for cold storage has limited the widespread use of the vaccine within eradication programs.
Economic Losses: Economic losses from PPR across Africa and Asia are estimated to be US $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 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, making the vaccine widely accessible and reducing logistical challenges.
Extended Shelf Life: Remains effective for up to two weeks at ambient temperatures, ensuring vaccines remain potent even in areas with limited refrigeration facilities.
Proven Effectiveness: Demonstrated efficacy in several countries, 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.
