Her mmr 2 vaccine is due on 10 dec...as on card it is written it should be done while completing 15 month...but I have query here...actually mmr 1 vaccine is given at 9 months but due to some health issues my baby couldn't get it at 9 months...she got mmr 1 dose at 11 months...there should be gap of 6 months minimum between two doses...but if I give her mmr2 on 10 dec there will be gap of only 4 months...I want to knw frm docs here do I have to wait for two more months for mmr2 shot... Or I can give after 4 months as well...how much gap should b there between two doses...plzzz help
