Pregnancy and lactation:
There are currently no data available on the use of Pandemrix™ (H1N1) in pregnancy. Data from pregnant women vaccinated with different inactivated non-adjuvanted seasonal vaccines do not suggest malformations or foetal or neonatal toxicity.
Animal studies with Pandemrix™ do not indicate reproductive toxicity.
The use of Pandemrix™ (H1N1) may be considered during pregnancy if this is thought to be necessary, taking into account official recommendations.
Pandemrix™ (H1N1) may be used in lactating women.

PS: Se a OMS não tivesse alterado a definição de pandemia, a Pandemrix não poderia ser usada em grávidas.
