Pocholo was given a vaccine last December 26,2016. Just today, I noticed a small soft lump on his skin at the back where the injection was administered. It's like a cyst with water inside because it's very soft. Is Pocholo be okay and if I will apply a hot compress, will it be gone?

That is a very common occurrence after vaccination. The vaccine can cause a localized reaction and it should resolve on its own within a month. If it persists, seems larger, or bothers him that have your vet take a look at it.
