marek’s vaccine after 24hrs

[venovee]

hey yall, question about vaccinating for marek’s.

i have chicks set to hatch tomorrow (friday mar 14th). i ordered the marek’s vaccine last night (wednesday) expecting it to ship today. it hasn’t shipped, and the place i ordered from doesn’t ship on friday, saturday, or sunday. the vaccine likely won’t get here until early next week. my bad for not i’ve had confirmed cases of marek’s in my flock.

so my question is, if these chicks are nowhere near the rest of my flock, and i’m diligent in changing clothes, shoes, etc. am i still ok to vaccinate them when the vaccine gets here? they’ll be older than 24 hours obviously, so will the vaccine still have any effect? i know the 24 hours is to mitigate exposure, so it won’t be as effective, but is it still worth it to vaccinate?

edit: the vaccine shipped last night so false alarm!

I think it's best in the first 24 hours, but as long as it's no more than a week was my understanding of it.
