What it is:
DIVA vaccines are designed to produce a specific immune response, often based on deletions or modifications of the pathogen’s antigens, that can be distinguished from the immune response caused by natural infection.
How it works:
A DIVA vaccine induces an immune response that can be detected using a diagnostic test, allowing for the identification of vaccinated animals.

Vaccination

The DIVA strategy (Differentiating Infected from Vaccinated Animals) in poultry vaccination involves using vaccines that allow for the distinction between vaccinated and infected birds. This approach is crucial for effective disease control, as it helps monitor vaccine efficacy and track disease outbreaks. It enhances biosecurity measures and supports trade by ensuring that vaccinated flocks are not misidentified as infected.

The DIVA (Differentiating Infected from Vaccinated Animals) strategy in poultry vaccination aims to distinguish between birds that have been vaccinated and those that have been infected with a disease, like avian influenza. This is crucial for effective disease control and eradication efforts.

Very good one

The <strong data-start=”4″ data-end=”21″>DIVA strategy in poultry vaccination stands for <strong data-start=”56″ data-end=”111″>”Differentiating Infected from Vaccinated Animals.” It is a disease control approach that allows health authorities to distinguish between animals that are <strong data-start=”216″ data-end=”238″>naturally infected with a pathogen and those that are <strong data-start=”274″ data-end=”288″>vaccinated.<div>
Why DIVA is Important:
<b data-start=”713″ data-end=”764″>1. <strong data-start=”723″ data-end=”764″>Supports Disease Eradication Programs
<ul data-start=”765″ data-end=”936″>
Allows accurate <strong data-start=”783″ data-end=”822″>surveillance and outbreak detection in vaccinated populations.
Critical for controlling diseases like <strong data-start=”891″ data-end=”910″>avian influenza or <strong data-start=”914″ data-end=”935″>Newcastle disease.
<b data-start=”938″ data-end=”990″>2. <strong data-start=”948″ data-end=”990″>Maintains Trade and Export Eligibility
<ul data-start=”991″ data-end=”1155″>
Many countries restrict imports from areas with outbreaks.
DIVA enables <strong data-start=”1067″ data-end=”1117″>vaccination without losing disease-free status, as infections can still be detected.
<b data-start=”1157″ data-end=”1191″> 3. <strong data-start=”1167″ data-end=”1191″>Improves Biosecurity
<ul data-start=”1192″ data-end=”1283″>
Helps identify and isolate <strong data-start=”1221″ data-end=”1240″>infected flocks even when vaccination is widely practiced.
<b data-start=”1285″ data-end=”1333″> 4. <strong data-start=”1295″ data-end=”1333″>Reduces Culling of Healthy Animals
<ul data-start=”1334″ data-end=”1455″>
In an outbreak, DIVA helps distinguish truly infected birds, avoiding mass slaughter of vaccinated but healthy animals.
