The major advantage of killed vaccines is their safety; the disadvantages are that they often require multiple doses to elicit and sustain an effective immune response and that the immune response may be imbalanced, leading to subsequent potentiation of the disease (14,15).

Recombinant: Similar to killed vaccines in that they are noninfectious, recombinant vaccines are produced using DNA technology to induce bacteria to produce proteins that are subsequently administered to induce an immune response.

Infectious bronchitis virus (IBV) mostly infects chicken (Gallus gallus) and is ubiquitous in Asia since 1967 (Lohr, 1981), despite the use of live attenuated and killed vaccines. It is highly contagious disease (Colvero et al., 2017) and present everywhere especially where poultry are present and it can spread very quickly in non-vaccinated birds.

Traditional avian influenza (AI) vaccines are killed vaccines, produced either by conventional methods or by reverse genetics [5] which provide good protection against the clinical disease caused by HPAIVs and significant reduction in viral shedding, if the vaccine seed strain is antigenically matched to the challenge strain [6].

Killed vaccines on the other hand usually require two doses, the first to prime the system and the second a short period later to produce the protective immunity with regular boosters.
