I've just posted a query about injecting Heptavac subcutaneously and had some really useful replies (thank you), but now I have a question about the actual effects after vaccination. I have 4 ewes, so when I inject I always use 4 brand new needles and syringes. Each year some or all of them get lumps on their necks where I've injected. The lump eventually bursts and there are no problems, but why do they get them?
My other concern is for the last 2 years one of my ewes has shown effects after the injection (despite having had injections for the last 4 years without any effects) Two years ago she was just not 'normal ' for a couple of days and was licking her lips a lot. Last year a few hours after the injection, she was lying down and seemed to be 'twitching'. I'm just a bit worried about the effects this year and wondered if anyone else has had anything similar? Thanks.
