Here's some information on efficacy of stored Newcastle Disease (ranikhet) vaccine. Probably not the same brand but may be useful for a general guideline.

Doesn't Newcastle vaccine actually have the virus in it,so your birds build immunity to it ? Or I'm I just talking hogwash.:p
I think they contain a live virus, yes but I am not sure if all of them (all brands) do. Most vaccines for other diseases contain a subunit of the virus.

Thank you so much for your help btw do chicks get alittle weaker and tired after vaccinating them ? Or something is wrong

I assume they know what they are doing..but the thought of my birds getting sick from vaccinated birds struck my mind.
