Maternal vaping linked to sudden infant deaths in New Zealand study
A new study from New Zealand researchers suggests a potential link between maternal vaping and Sudden Unexpected Death in Infancy (SUDI). The findings indicate that vaping, especially when combined with bed-sharing, may carry similar risks to smoking during pregnancy.

A New Zealand study has linked maternal vaping and sudden infant deaths.
The study of 101 Sudden Unexpected Death in Infancy (SUDI) deaths in New Zealand in 2022 and 2023 had detailed information about maternal nicotine exposure and the infant’s sleep environment for 66 cases, the University of Auckland and University of Otago said in a joint statement.
“Maternal vaping is emerging as a potential risk factor for Sudden Unexpected Death in Infancy (SUDI) … [the] findings highlight the need to reassess public health messaging around vaping in pregnancy and bed sharing.”
The interaction between maternal smoking and bed-sharing was well-established, said the report’s lead author, Professor Ed Mitchell, of Waipapa Taumata Rau, University of Auckland.
