DS had his on Weds just gone and we had no temperature but the pneumococcal one left a raised red leg for the rest of that day. He was fine until about 5 hours after the needles then we got about 2 hours of really unsettled grizzly crying stuff. He had no temperature but I think was generally not a happy chappy and maybe the rotavirus syrup had upset his tummy a bit....we gave him some infant panadol and he settled right down pretty quickly....gave him another dose at bedtime and he has been fine since then. So in the scheme of things he probably had a very mild reaction so not too bad overall...hope that helps.....
