Empowering mothers worldwide through connection, support, and shared experiences ✨
Moms report roughly 2-3 vaccinations during pregnancy, generally given after about 20 weeks (not in the first trimester). The current standard is TDAP (replacing older plain tetanus), often given twice, plus a flu shot; Anti-D may be needed for Rh-negative moms.
⚠️ Caution:There is genuine variation in practice (plain tetanus vs TDAP, number of doses). Confirm the correct schedule with your own gynaecologist, especially regarding Rh status and Anti-D.
Moms get anxious when different doctors give conflicting advice - for example one giving two tetanus doses and another saying TDAP should have been given directly. The community's reassurance is that the shift from plain tetanus to TDAP explains much of the confusion, that vaccines come in a window of weeks rather than one exact week, and that the right move is simply to confirm the list with your own gynaec rather than panic over the differences.
Here's what moms in our community shared based on their own experience.
There are usually about 3 vaccinations during pregnancy. The 9th week / 2-3 months is too early - moms were typically given them after the 20th week or around the 5th-7th month. Your gynaec will tell you when the time comes.
Tetanus/TDAP (often two doses a few weeks apart) plus a flu vaccine. The flu shot helped one mom with allergies and gives the baby protection from birth; she took it around the 28th week.
Anti-D may be given if your husband is Rh positive and you are Rh negative, so check with your gynaec.
On the tetanus vs TDAP confusion: a nurse explained that earlier plain tetanus was given but now TDAP (Tetanus, Diphtheria, Pertussis) is given instead. Some moms received 2 TDAP doses; in a second pregnancy less than 3 years apart, only one dose was given.
Vaccines are given over a range of weeks, not one specific week - check with your gynaec for the exact list and schedule.
