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 project

The technology reduces economic losses and poverty among small ruminant farmers by preventing PPR outbreaks and enhancing food security. It improves animal health, reduces disease spread, and fosters economic growth in the agricultural sector. Additionally, its innovation in vaccine technology promotes sustainability and contributes to climate action efforts.

To incorporate this technology into your project, the following steps and considerations are recommended:

Ensure the availability and affordability of thermostable vaccines for small ruminant producers.
Educate producers about the advantages of PPR vaccination and ensure their willingness to invest in vaccine administration.
Encourage adherence to instructions provided by animal health professionals regarding vaccine administration.
Provide training and certification to animal health professionals in accordance with national regulatory standards to ensure proficient vaccine administration.
Ensure vaccine quality meets national or regional standards to achieving good immunity of herds
Calculate the required quantity of products needed for your project based on an initial cost ranging from 0.3-0.5 USD per animal. Consider additional expenses such as delivery costs, import clearance, and duties, particularly if the technology is sourced from other countries.

A team of trainers can offer support and training during the installation phase of the project. Budget for training and post-training support for utilizing the technology effectively.

Consider collaborating with agricultural development institutes to facilitate the implementation of the technology within your country.
