Is it the nobivac myxoRHD vaccine this side effect, a scab at the injection site is known, but not considered grave. You can rinse it with saline (human eye wash is fine). You can use plain neosporin cream on it (polymyxin B). If you see any signs of an abscess forming, you should get a vet appointment.
Dry sounds good to me though, it’s wetness and seepage you don’t want.
I found this on Nobivac myxo-RHD:
4.6 Adverse reactions (frequency and seriousness) A transient temperature increase of 1-2° C can occur. A small, non-painful swelling (maximum 2 cm diameter) at the injection site is commonly observed within the first two weeks after vaccination. The swelling will resolve completely by 3 weeks after vaccination.

The easiest way to get your pics up is to upload to photobucket or imgur or other external source, then paste the link or the picture into your post.
I vaccinate my buns yearly with this vaccine.
