Do you know if Ceba has a representative in the Philippines? Where we can buy the two brands of pox-vectored vaccines for ILT?

If your farm is free from ILT Do not go for the live vaccine unless it is a pox vectored vaccine.

Otherwise, do the live vaccination 2 weeks before the expected age of outbreak.
