A Ugandan innovation for livestock health

A new approach to protecting cattle from ticks

NAROVAC is Uganda's locally developed anti-tick vaccine. It is designed to support the control of cattle ticks by helping the animal's immune system respond to them.

NAROVAC information on this website is provided for public education. Availability and use remain subject to the applicable regulatory approvals and official guidance.

A vaccine developed for the realities of cattle production in Uganda

NAROVAC is an anti-tick vaccine developed through research conducted in Uganda. Unlike chemical acaricides, which act directly on ticks outside the animal, NAROVAC works through the vaccinated animal's immune response.

The vaccine is intended to form part of an integrated approach to tick control. Farmers should continue to follow approved veterinary guidance and should not change existing livestock-health practices without professional advice.

Why tick control matters

Ticks affect animal health, productivity and farmer livelihoods.

Cattle ticks can weaken animals and contribute to the spread of tick-borne diseases. Managing them can also require repeated use of chemical acaricides, creating costs and practical challenges for farmers.

NAROVAC research is focused on providing an additional, locally relevant tool that can support safer and more sustainable tick-control practices.

How it works

The animal's immune response becomes part of tick control.

1

Vaccination

NAROVAC introduces selected tick proteins to the animal's immune system.

2

Immune Response

The animal produces antibodies that circulate in its blood.

3

Tick Feeding

When a tick feeds on the vaccinated animal, it takes in these antibodies.

4

Disruption

The antibodies target important tick proteins, affecting feeding, development or reproduction.

5

Longer-term Control

Reduced tick survival and reproduction can contribute to a gradual reduction in tick burden.

This overview describes the general mechanism of action. For detailed scientific information, please refer to the published research on the Evidence page.

Benefits of using the vaccine

  • The use of NAROVAC® Anti-Tick Vaccine will lead to an overall reduction in acaricide use and failure, improved animal health and well being, reduced contamination of the environment especially water and soil, and animal source foods.
  • The overall integrated vaccine effectiveness was estimated at 75% – 99%, showing a strong capacity to reduce tick populations and, consequently, the risk of tick-borne diseases and associated health complications in cattle.
  • The application of NAROVAC® is expected to reduce acaricide application frequency from 104 rounds a year to about 12 times in a year per animal.
  • The use of the NAROVAC® Anti-Tick Vaccine will enable livestock farmers to break even at a lower cost.
  • The application of NAROVAC® Anti-Tick Vaccine will lead to reduced national import bill for acaricides.
NAROVAC research and development

Evidence developed through research

NAROVAC's development is supported by published research on anti-tick vaccination, field evaluation and cattle-tick control in Uganda. The evidence library brings these publications together in one place for researchers, veterinary professionals, institutions and the public.

Official Launch & Commissioning

Presidential Launch of the NAROVAC Anti-Tick Vaccine

His Excellency the President of Uganda officially launched the NAROVAC Anti-Tick Vaccine, marking a historic milestone in Uganda's agricultural innovation and livestock health management.

The same occasion included the commissioning of the NAROVAC Anti-Tick Vaccine manufacturing facility, strengthening Uganda's capacity to produce the vaccine locally.

The launch underscores the Government of Uganda's commitment to locally developed and locally manufactured solutions for Ugandan farmers and the wider livestock sector — a demonstration of the Buy Uganda, Build Uganda (BUBU) agenda in action.
