So today my husband took my son for his pre-school vaccinations. The appointment has been rescheduled by the practice three times and today I couldn't take him myself but thought it would be fine... Anyway the nurse did the first injection and my son pulled away and she scratched his arm with the needle. My husband said he was then very upset and struggling so when she did the second one she scratched him again and less then half of the vaccine went in. She said that this was fine and he couldn't have another one just in case some went in. Is this correct? I have come home from work as he was inconsolable (he's under assessment for autism) and his whole arm is bruised and his t-shirt is soaked with blood and vaccination fluid. I'm furious and kicking myself for not being with him. Also worried that he hadn't received enough vaccination (was the mmr one). Shall I complain? Thanks in advance!
