I had my C-section on 19.06.2020 . I have twins babies one baby boy and me baby girl. now I am confused regarding pcv vaccination. as my baby boy gets first dose of pcv after 1 1/2 months of his birth I.e. on 03.08.2020 and second dose after 3 1/2 month I e. on 03.10.2020 and going to get third dose,( buster dose) on 9 months. but in case of my baby girl she missed her first dose as per schedule mentioned in immunization card. she gets her first dose on 31.10.2020 after two months of her birth and second dose after ,8weeks gap i.e. 26.12.2020 after that they called me after one month for buster dose . I would like to know why there is difference of buster doses in my both baby case #Vaccination
