Research objective: 

Research Questions:

1. Does the age at receipt of immunization in BCs routine immunization schedule differ among infants whose mothers had midwives compared to those who had other types of maternity HCPs?

2. Do the proportions of infants who had documented refusals to routine immunizations (one or more routine immunization; all routine immunizations) differ among infants whose mothers had midwives compared to those who had other types of maternity HCPs differ?

3. Do the proportions of infants who are unimmunized by the second birthday differ between infants whose mothers had midwives compared to those who had other types of maternity HCPs?

4. Do the proportions of infants who received all routine immunizations by the second birthday differ among infants whose mothers had midwives compared to those who had other types of maternity HCPs?

5. Does adherence to the BC routine immunization schedule differ among infants whose mothers had midwives compared to those who had other types of maternity HCPs?

Hypotheses:
1. Infants whose mothers had midwives are more likely to have delayed commencement of routine immunizations, when compared to infants whose mothers had other types of maternity HCPs.
2. Infants whose mothers had midwives are more likely to have documented refusals to one or all routine immunization(s), when compared to infants whose mothers had other types of maternity HCPs.
3. Infants whose mothers had midwives are more likely to be unimmunized (completely unimmunized and unimmunized for specific series), when compared to infants whose mothers had other types of maternity HCPs.
4. Infants whose mothers had midwives are less likely to have received all routine immunizations by the second birthday, when compared to infants whose mothers had other types of maternity HCPs.
5. Infants whose mothers had midwives are less likely to have adhered to BCs routine immunization schedule, when compared to infants whose mothers had other types of maternity HCPs.
