Nearly a quarter of a million people have signed a petition calling for all children to be given a meningitis vaccine following the death of a two-year-old girl.
Faye Burdett, from Maidstone, died on Valentine's Day after fighting the infection for 11 days.
Her story, told by her mother Jenny, has been widely shared on social media including Facebook and Twitter.
Faye's family said they are enduring "a pain you cannot describe" after the toddler contracted meningitis B.
A vaccine to protect against meningitis B is available on the NHS for babies aged two months, followed by a second dose at four months and a booster at 12 months.
Parents who wish to have older children vaccinated must pay privately, although a worldwide shortage of the vaccine Bexsero means stocks are very low.
Manufacturer GlaxoSmithKline (GSK) hopes to have increased stocks in the UK by the summer. The NHS programme is unaffected.
Mrs Burdett has published photos of her daughter, including one of her in ahospital bed just before she died.<
Faye was taken to A&E with a rash on her forehead. She was then transferred by South Bank Retrieval Service to Evelina Children's Hospital, where her heart stopped in the ambulance. They revived her and spent hours working on stabilising her.
We were given a 1% survival chance but she proved them wrong and carried on fighting.
Mrs Burdett called on people to sign the petition asking the Government for the meningitis B vaccine to be given to all children, not just newborn babies.She said all children were at risk, and there should be a rollout programme to vaccinate all children, at least up to age 11.
