Infections & vaccinations in pregnancy

Key basics

Live vaccines

Live vaccines (e.g., MMR/varicella) are generally not recommended during pregnancy. Ideally, vaccination status is checked before pregnancy.

Hygiene helps (CMV & toxoplasmosis)

Wash hands regularly (especially after contact with diapers/body fluids of young children).
Do not share cutlery/cups with young children.
Cook meat thoroughly; wash vegetables/salad carefully; use caution with raw-milk products.

RSV – protection options (mother or baby)

In Switzerland there are protection options for newborns against RSV: either via maternal vaccination (typically 32+0 to 36+0 weeks if the due date falls within the RSV season) or via passive immunisation of the infant (e.g., nirsevimab – depending on birth month/RSV season). Usually one method is chosen; combining both methods is generally not necessary. We will advise what makes sense for you.

Costs Vaccinations count as prevention – your deductible may apply.
