A 32-year-old woman has died following swine flu "complications" two weeks after giving birth to a son, a hospital has said.
The family of Sarah Applin, 32, of Thurston, Suffolk, urged pregnant women to opt for vaccination.
Staff said Mrs Applin died at West Suffolk Hospital in Bury St Edmunds on Tuesday.
"Our daughter ... sadly died ... of complications with pneumonia following treatment for swine flu," said her parents, Jane and Barry Waterman.
"We would like to strongly urge any person on the at-risk register, especially pregnant woman, to have the flu vaccination."
Family members said Mrs Applin gave birth to son William by Caesarean section on December 22.
Mrs Applin and her husband Richard also had a four-year-old daughter.
Her parents run a pub in Beyton, Suffolk.
