For 6 in 1 there are 3 jab, last one done at 5th mth. Think after the jab (even for adults) every doc will tell u to expect some fever, they will also give the panadol syrup tell u to give to your baby if temp above 38degrees. My gal had some mild fever the night after the jab..like 37.5deg, I fed her with the syrup and she went to sleep, the next day she was back to normal Liao.thanks for sharing. there are only two jabs to 6 in 1? Wld there be any symptoms after the jab? I've heard that for some jabs, the baby will have fever after a few days all part of the anti-bodies reaction to the jab.
