Breaking news: An international analysis released today shows vaccination coverage for major farm animals remains dangerously low across cattle, poultry, and pigs, jeopardizing food security and public health.
The study, published in the Proceedings of the National Academy of Sciences, compiles two decades of country‑level data on vaccination programs and disease incidence.The researchers pooled national reports and data from the World Animal Health Network to establish a baseline for improved prevention and control of livestock diseases.
Researchers say farm animals share close quarters, which drives transmission and can trigger outbreaks that threaten livelihoods and food supplies.The analysis highlights 11 diseases moast targeted by official vaccination programs and reveals coverage gaps across regions.
Bottom line: vaccination rates across cattle, poultry, and pigs are far below what is needed to prevent outbreaks that threaten food security and pose zoonotic risks. The authors warn that global vaccination trends in at‑risk regions have remained stagnant over time and call for a data‑driven approach to guide policy and practise.
Key figures include: cattle – 16.64% for foot‑and‑mouth disease, 33.80% for lumpy skin disease, 11.57% for anthrax, and 7.93% for rabies; poultry – 16.71% for infectious bronchitis and 17.62% for Newcastle disease; pigs – 6.56% for classical swine fever, 4.96% for anthrax, and 8.08% for rabies.
Geographic gaps were flagged as the strongest warning signs. India and Argentina emerged as weak links for cattle diseases; china and Russia were highlighted for pig diseases; and China, Brazil, and Iran were singled out for poultry. In China, one disease case stands out: estimated anthrax cases in pigs for 2025 could reach 118, with vaccine coverage at about 1%.
Experts say the findings should compel policymakers to synthesize disease transmission data with vaccination coverage to set a credible global health baseline. International health bodies emphasize that increasing livestock vaccination is central to food security, animal welfare, and reducing zoonotic risk. For broader context, see WOAH updates and FAO policy briefs on vaccination strategies.
| Disease | Species | Vaccination Rate (%) |
|---|---|---|
| Foot-and-mouth disease | Cattle | 16.64 |
| lumpy skin disease | Cattle | 33.80 |
| Anthrax | Cattle | 11.57 |
| Rabies | Cattle | 7.93 |
| Infectious bronchitis | Poultry | 16.71 |
| Newcastle disease | Poultry | 17.62 |
| Classical swine fever | Pigs | 6.56 |
| Anthrax | Pigs | 4.96 |
| Rabies | pigs | 8.08 |
two questions for readers: What should governments prioritize to close these gaps? How can producers be incentivized to vaccinate in regions with low uptake? Do you think consumer demand for safer, vaccine‑backed products could accelerate change?

Rise in local food‑price inflation (Kenya Ministry of Agriculture, 2023).
Key Statistics Highlighting Global Vaccination Gaps
- Only ~45% of cattle in low‑income regions receive at least one core vaccine annually (FAO, 2023).
- Livestock‑origin zoonoses account for 60% of emerging infectious diseases, yet immunization coverage for high‑risk species remains below 30% in many parts of Sub‑Saharan Africa adn South‑East asia (OIE, 2024).
- Economic losses from preventable diseases exceed US$ 12 billion each year, with the majority stemming from reduced milk yield, lower meat production, and increased mortality (world Bank, 2024).
These figures illustrate how vaccination gaps directly erode food security and strain One‑Health initiatives.
How Vaccination Shortfalls threaten food Security
- Reduced Livestock Productivity
- Unvaccinated bovines suffer a 10-15% drop in milk output during endemic outbreaks of brucellosis or bovine viral diarrhea (BVD).
- Smallholder poultry flocks experience up to 40% mortality from Newcastle disease when vaccination rates fall below 20% (FAO, 2022).
- higher Feed‑to‑Food Conversion Ratios
- Ill animals require more feed to maintain body condition, inflating production costs and diminishing net protein availability for vulnerable populations.
- Supply‑chain Disruptions
- Outbreaks trigger market bans, causing price spikes for meat, milk, and eggs, which disproportionately affect low‑income consumers.
One‑Health Implications of Unvaccinated livestock
- Zoonotic Spillover: Uncontrolled Rift Valley fever in goats and sheep drives human cases in East Africa, where vaccination coverage is under 25% (CDC, 2023).
- Antimicrobial Resistance (AMR): Farmers often resort to prophylactic antibiotics when vaccines are unavailable, accelerating AMR in both animal and human pathogens (WHO, 2024).
- Environmental Impact: Disease‑related carcass disposal increases greenhouse‑gas emissions and contaminates water sources, undermining lasting agriculture goals.
Regional Case Studies
1. sub‑Saharan Africa – Foot‑and‑mouth Disease (FMD)
- Situation: In 2022,Kenya reported >5 million cattle at risk; only 38% received FMD vaccine due to cold‑chain constraints.
- Impact: Milk production dropped 12% in affected districts, contributing to a 7% rise in local food‑price inflation (Kenya Ministry of Agriculture, 2023).
2. South‑East Asia – Avian Influenza (H5N1)
- Situation: In Vietnam, backyard duck farms have a 22% vaccination rate, despite the virus’s endemic presence.
- Impact: Human infections rose by 15% in 2023, prompting WHO to label the region a “critical hotspot” for One‑Health collaboration (WHO, 2023).
3. Latin America – Bovine Brucellosis
- Situation: Brazil’s national brucellosis program achieved 60% coverage in commercial herds but only 28% in smallholder operations.
- Impact: Estimated loss of 1.2 million liters of milk per year, undermining the country’s goal of zero‑deficiency nutrition for children (Brazilian Ministry of Health, 2024).
Barriers to Effective Livestock Immunization
- Infrastructure Gaps
- Inadequate cold‑chain facilities limit vaccine potency, especially in remote villages.
- Financial Constraints
- Smallholder farmers often cannot afford the per‑dose cost; lack of subsidy schemes exacerbates low uptake.
- Knowledge Gaps & Vaccine Hesitancy
- Misconceptions about vaccine safety led to refusal, mirroring trends seen in human health campaigns.
- Regulatory Hurdles
- Delayed approval of new livestock vaccines stalls adoption of more effective formulations.
Innovative Solutions & Best Practices
| Solution | How It Works | Real‑World Example |
|---|---|---|
| Thermostable Vaccines | Formulations remain effective without strict refrigeration,simplifying distribution. | Rwanda’s 2023 rollout of a thermostable Rift Valley Fever vaccine reduced cold‑chain costs by 40% (Rwanda veterinary Authority). |
| Mobile Vaccination Units | Equipped vans travel to remote farms, offering on‑site inoculation and record‑keeping via apps. | India’s “Livestock Mobile Clinics” inoculated 1.8 million cattle in 2022, raising coverage from 31% to 55% in targeted districts (ICAR, 2023). |
| Digital Immunization Registries | Blockchain‑based platforms ensure traceability, reduce falsified vaccines, and provide real‑time coverage data. | kenya’s “e‑Vaccinate” pilot linked 4,500 smallholders to national databases,improving reporting accuracy by 73% (Kenya ICT Authority,2024). |
| public‑Private Partnerships (PPP) | Pharmaceutical firms co‑fund vaccine procurement while governments handle logistics. | Brazil’s PPP for Bovine Brucellosis packed 2 million doses at reduced cost, achieving 68% coverage in the first year (ABCP, 2024). |
Practical Tips for Farmers & Policy‑Makers
- Assess Local Disease Risk
- Use OIE’s risk‑mapping tools to prioritize vaccines for the most threatening pathogens in your region.
- Leverage Group Purchasing
- Join farmer cooperatives to negotiate bulk discounts and share cold‑chain equipment.
- Adopt Simple Cold‑Chain Practices
- Utilize insulated vaccine carriers with ice packs; rotate stock based on “first‑expire‑first‑out” to maintain potency.
- Integrate Vaccination with Routine Herd Checks
- Combine deworming, nutrition counseling, and immunization in a single farm visit to reduce labor costs.
- Engage Extension Services
- Schedule quarterly workshops with veterinary extension officers to stay updated on new vaccine releases and dosing schedules.
- Document Immunization Events
- Use mobile apps (e.g., “VetTrack”) to log dates, batch numbers, and animal IDs, creating an audit trail for future disease investigations.
- Advocate for Government Incentives
- Lobby local authorities for subsidies,tax breaks,or vouchers targeting smallholder vaccination programs.
future Outlook: Closing the Immunization Gap
- Scaling Up Research: investment in next‑generation vaccines (e.g., mRNA platforms for livestock) could cut development time and improve strain specificity.
- Strengthening One‑Health Networks: Joint surveillance between animal health, human health, and environmental agencies enables early detection of spillover events, guiding timely vaccination campaigns.
- Building climate‑Resilient Supply Chains: Solar‑powered refrigeration units and drone delivery of vaccines to hard‑to‑reach areas promise to mitigate climate‑induced logistical disruptions.
By aligning vaccination strategies with food‑security goals and One‑Health principles, stakeholders can safeguard livestock productivity, protect public health, and enhance global nutrition resilience.
