A spokesperson for the HSE has said there have been no additional cases of meningococcal disease.

Eleven cases have been notified to the Health Protection Surveillance Centre since the last week in December, compared to five for the same period last year.

There have been three deaths directly due to the infection.

Parents have also been urged to make sure their children have had meningitis inoculations

"As of today no additional cases of meningococcal disease are notified, nor are there any additional deaths to the three deaths previously reported," said the spokesperson.

More than 11,000 people have signed an online petition calling for "the Minister for Health Simon Harris to implement a catch-up vaccination programme for the meningitis B programme for all children and teens".

In 2016, the Department of Health made a decision to provide a free Meningitis B vaccination for all babies born after 1 October 2016.

This was based on the independent advice of the National Immunisation Advisory Committee.

The NIAC has never recommended a catch-up programme for this vaccine.

Children not covered under the Primary Childhood Immunisation Schedule pay for the vaccination.

The cost of the vaccine is €180 per shot and two-three shots are required.

This evening, the HSE confirmed that none of the three recent meningitis deaths can be attributed to Meningitis B.
