suspected Mareks lost a chicken today help

[Pheobe_nz]

I have had a sick chicken she was about 18weeks
I hatched her from fertile eggs
She started to limp on left leg took her to vets and they said injuiry but could be mareks treated her with antibiotics and steroids and seperate her and limit movement so she could heal.Was at vets thursday and she seemed a bit better well today she couldnt even stand anymore and her wing had dropped to the side,
Vet thinks Mareks so had her put to sleep
I didnt have postmortem done but they are pretty sure
So now I have my other chickens at risk aged 18 weeks to 18months
So can I get hold of Vac for mareks and treat incase?
No others showing signs at all vet suggested vac and Im trying to sorce vac now.
Just wondering when most info says to vac day old chicks
with mine other hens not showing signs of Mareks but are high risk can I vac now?
Thanks for any advice info
Natasha

I don't know anything about Mareks but here is an older thread that might be helpful about vaccinating older chickens. https://www.backyardchickens.com/forum/viewtopic.php?id=462327

did you vet feel swelling in the liver and lymph nodes? Did he/she check?
