Now let me ask another question. Supposing I have about 15 birds (Chickens) and I want to administer a Lasota vaccine and I could not get smaller dose I bought a 50 dose divide the powder. Can I refregerate the other unused part for next use?
Is there a label or box that says anything like “refrigerate after using” or an expiration date?
It appears than Lasota is a strain of Newcastle virus vaccine.
I found this. It says to refrigerate between 2-8°C:

It might be different from another manufacturer.
