I want to ask if a vaccine should be given in 9 month then 1st dose of it should be given after completing 9 month or it can be given after  completing 8 month and before completion of 9 month. Actually my daughter dob is 18-01-16 and her flu vaccination which is to be done at 6 months but has been done on 07-07-17 (while she was running in 6 months) so is it ok and similarly mmr 1dose and hepatitis b 3rd dose also given 8-10 days before completing the respective month which is recommended for vaccination i mean all vaccination are done under running month lyk swine flu vaccine should be given at 6 month hepatitis b 3 dose should be givenat 6 mont h and mmr 1 should be given in 9 month but all these vaccination for my baby is given 8-10 days before completing these monyhs is it ok or it will effect the vaccine results
