Any parents have given flu vaccination to your LO at 7 months old? Is it effective ? We are thinking of giving to our LO as he will be going to infant care next month. I know the cons of infant care is that LO will fall sick easily . So besides pumping up on his nutrients intake from solid food and milk, I thought of flu jab. PD says can give from 6 months and above. He has taken the rotavirus jab too .
