Importance of Vaccination and Canine Adenovirus Type 2 (CAV-2) Infection

Back in 1980, the World Health Organization announced that smallpox had been completely eradicated globally. Similarly, Wild poliovirus has also been eradicated except in two Asian countries – Pakistan and Afghanistan. This disease is still endemic in both countries. The credit of successful global eradication of these diseases goes to vaccination development and drives. Vaccination helps in triggering an immune response against the disease.
