Hello, Thank You For Being Available. My Child Was Innoculated

Hello, thank you for being available. My child was innoculated with Pentaxim this morning. I live in the country in South Africa. The chemist ordered it for me, cost R400. The doctor administered the innoc. He put it on our medical aid. No-one said anything to me about the expired innoc. I noticed only now that the Lot no J4019 - 1 expired on the 05 - 2014. I am horrified. Are there any serious consequences, how will this affect him in the long run and most importantly will the innoculation still protect my son against the diseases that Pentaxim is supposed to protect him from? Hope to hear from you soon. Regards, Georgia
