No Intervention: Opting in
Currently, pregnant women have to sign a consent stating that they want the influenza vaccine (at the clinics where the study is being conducted). Therefore, this group is the same as usual care. However, women will then be asked if they would like to take part in parts 2 and 3 of the study.
Experimental: Opting Out
Women will sign a consent form only if they do not want to receive the flu vaccine.
Other: Opting Out
Usual care is for pregnant women to sign a consent to get the influenza vaccine. The intervention is to offer a group of women the option to sign only when they refuse the influenza vaccine.
- Vaccination rates [ Time Frame: up to 24 weeks ]Vaccination rates will be analyzed for the two groups (opting in vs opting out) to determine group vaccination rate.
