lump at vaccination site

[DownUnder Gal]

Some goats are very sensitive to the adjuvant in the vaccine and unfortunately it doesn't matter how much you disinfect the site (which I always do) prior to vaccinating, those goats will still get the reaction. I never use the same needle twice and I swab the site prior. My ferals generally get the reaction but my dairy goats do not. We did a controlled experiment with the vet - the vet vaccinated the herd a couple of times because I thought I was doing something wrong - not so. Regardless of who did the vaccinating, the same goats got the same reaction. Interestingly the ones that get the worst reactions are the ones that did not receive any colostrum when they were born.
