Former England rugby union captain Matt Dawson has revealed his family went through “two weeks of hell” as his two-year-old son battled meningitis W135.
Sam Dawson underwent treatment at Great Ormond Street Hospital.
The 2003 World Cup winner said he decided to speak out after a petition calling for all children to be vaccinated against the B-strain of the infection gained 400,000 signatures .
But experts warned they needed to see how effective the vaccine would be.
The campaign was started after two-year-old Faye Burdett died from the B-strain.
In a series of tweets, 43-year-old Dawson, who played for Northampton and London Wasps during his club career, said: “The 2 weeks of hell we’ve just had cos of Meningitis. Sami lucky due to amazing people @GreatOrmondSt #vaccinateNOW.
“I must also heap praise on @ChelwestFT [Chelsea and Westminster Hospital NHS Foundation Trust] for their superb A&E and recognition of Sami’s disease. We’re indebted.
“I ask one favour. Please read and sign so fewer kids suffer.”
The government’s petition website states that any petition garnering more than 100,000 signatures will be considered for debate in Parliament.
Faye’s story has been widely shared on social media after her mother Jenny Burdett, from Maidstone, Kent, published photos of her daughter lying in her hospital bed covered in a rash.
She said: “We campaign for change in her memory. There needs to be a roll-out programme to vaccinate all children, at least up to age 11.”
Vaccine newly introduced
A vaccine to protect against meningitis B became available on the NHS for children under the age of one in September, but parents who want to have older children vaccinated must pay privately.
The UK is the first country to have introduced the Men B vaccine.
James Stuart, a visiting professor at the University of Bristol and a World Health Organisation advisor, warned: “We need to know how well the vaccine is working. So it may not be the time yet to widen the programme.”
Meanwhile, Professor of infection and immunity at Great Ormond St Hospital and University College London, Nigel Klein, said: “We all hope [it] will be successful.
“However as yet we really don’t know how effective it will be and if there are going to be any problems and this is a major area of ongoing research supported by the Meningitis Research Foundation.”
The Department of Health said: “When any new immunisation programme is introduced, there has to be a date to determine eligibility.”
