I had my second vaccine today but unfortunately some of the vaccine seeped out , the vaccinator discussed it with the band 6 who advised her to give me a second one although did asked me if I wanted to come back in a weeks time , I was really unsure but went ahead and had a second vaccine in the same arm. Apparently is better to have a second dose rather than be under dosed and it does not matter having a double dose. Does anyone know if that is correct , my friend has told me maybe it was the technique of the vaccinator and she gave it to fast .
