Since September last year, a vaccine to protect against meningitis B has been 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 Glaxo Smith Kline (GSK) hopes to have increased stocks in the UK by the summer. Mrs Burdett has published photos of her daughter, including one of her in a hospital bed just before she died.
She said: "This is a photo of Faye, two years old, who sadly lost her life to this dreadful disease. "Faye was taken to A&E with a rash on her forehead.

"We were given a one per cent survival chance but she proved them wrong and carried on fighting.
"After a few days she seemed to have turned a corner, but the sepsis started to affect her more and the decision of limb removal was made.
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.
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.
Almost 250,000 people have signed a petition calling for all children to be given a meningitis vaccine following the death of a two-year-old girl.
