Cost effectiveness of poultry vaccination for control of H9N2 avian influenza in Pakistan
Lead Research Organisation:
Royal Veterinary College
Department Name: Production and Population Health
Abstract
H9N2 is endemic in poultry in Pakistan and for the last 16 years vaccines have been employed to reduce production losses. The virus remains endemic and vaccination programmes face numerous technical challenges, including optimal vaccine virus strain selection to accommodate the diversity of co-circulating virus variants, and strategic questions regarding risk-based targeted vaccination where disease is more prevalent.
This PhD research project companion the ZELS research programme between UK, Vietnam and Pakistan (http://combating-avian-influenza.com/) will address ongoing needs for systematic antigenic matching of H9N2 vaccine formulations to field variants, and design of novel H9N2 viral vectored vaccines and diagnostics. The proposed PhD project will build on this framework to investigate the complex socio-economic factors that contribute to the success or failure of vaccine interventions.
The project will develop models on AIV vaccine use and the scale and frequency of disease outbreaks inflecting overall economic losses in poultry production in Pakistan. The outcome of this research project will help to develop disease control strategies for sustainable growth of poultry production. Reduction in disease-related loses will directly improve socio-economic wellbeing of poultry farming communities.
The project will be conducted within the larger framework of a Zoonoses and Emerging Livestock Systems (ZELS) project, which aims to develop novel H5 and H9 influenza vaccines tailored to the circulating variants in Vietnam and Pakistan.

| Description | Technical skills : In form of qualitative and quantitative data collection along with their analysis using software like NVivo and R. Designing survey questionnaires and using Open Data Kit software for quantitative data collection. Transferable skills: Developed efficient presentation skills by attending various conferences and annual meetings. Findings: A trend towards integrated farming from independent farming was found. Poultry production industry is dependent on public and private sector for health related services. However, public sector is more involved in passive surveillance and private for vaccinations and diagnostics. Communication gap between public and private sector was evident. Involvement of middlemen in various systems renders threat to price instability and sustainability of poultry farming business. Avian influenza (H9N2) was found to be highly prevalent among poultry sector despite of regular vaccination in layers and occasionally in broilers. However, practising H9N2 vaccination regular in broilers was found to be cost effective as compared to no vaccination. Disposal of dead birds included dumping on land fills and water bodies along with routine burning and burying. It should be regulated to mitigate hot spots of viral transmission and environmental pollution. |
| Exploitation Route | Policies could be made to bridge the gaps between various stakeholders for the efficient flow of information to contain AI infection successfully. Models developed (after making it user-friendly) in this project will serve as a decision making tool for the farmer to decide the best and most cost-effective approaches to control disease and rear chickens. Efforts are being made to make models simple and user-friendly to be used by agriculture farmers. The potential barriers identified in the uptake of disease control measures will be efficiently communicated to the stakeholders and policymakers so that they could be addressed them well before time for the successful control of diseases. |
| Sectors | Agriculture Food and Drink Government Democracy and Justice |
| Description | The findings have been used to understand and estimate the economic impact of other diseases to make efficient disease control policies in Pakistan.
