Should you and your family get the meningitis vaccination?

"We are more likely to encounter different strains of these germs at different times in our life, which is why specific vaccinations are recommended depending on your age or situation," says Claire Wright, evidence and policy manager at the Meningitis Research Foundation.

Our generational guide explains who would benefit from having the meningitis vaccination.

Meningitis in babies and young children

"Around half of the 3,200 cases of meningitis that occur each year affect babies or children under five because their immune system is not fully developed," says Claire Donovan, head of information and research at Meningitis Now.

Hay numerosas vacunas que se administran a los bebés para protegerles contra las bacterias que pueden causar meningitis. A las ocho, 12 y 16 semanas se administra una vacuna contra la Hib (como parte de una vacuna combinada). La vacuna antineumocócica se administra a las ocho semanas, a las 16 semanas y al año. Se les vacuna contra la MenB a las ocho semanas, con refuerzos a las 16 semanas y al año. También se les administrará una inyección contra el MenC al año.

There is some controversy surrounding the MenB jab. Research into the vaccine's efficacy in September 2016 found it had halved the average number of MenB cases in vaccine-eligible age groups compared with four years previously.

As a result, some experts and parents think the vaccine, called Bexsero®, should be given on the NHS to all children under five, not just those born after the vaccine was introduced in September 2015 - one petition even proposed vaccinating children up to the age of 11.

However, the cost to the NHS would be huge; one estimate puts the total cost for immunising all under-fives in England and Wales against MenB at £189 million. If this were to include all under-11s, the equivalent cost would be £441 million.

Puede decidir vacunar a su hijo de forma privada, pero el número de casos de MenB está disminuyendo y vacunar a niños mayores de cinco años puede no ser eficaz. Según cifras de Public Health England, el 24% de los casos de MenB entre 2014/15 fueron en bebés de un año y el 33% en niños de uno a cinco años, pero solo el 12% de los casos fueron en niños de cinco a 14 años.

Meningitis in teenagers

Teens and young adults are the group with the second highest risk of contracting meningitis. As such, it's strongly recommended they receive the meningitis ACWY vaccination that protects against four main strains of the disease they are at risk of.

Right now, only 33% of eligible young people are vaccinated which does concern experts. Because teens are also the group most likely to carry meningococcal bacteria responsible for many cases of meningitis - thanks to typical teenage activities such as kissing and sharing drinks - vaccinating your teen may also help protect other members of the family.

Meningitis in adults

Most adults over the age of 25 don't need additional protection against meningitis. "The main exception is if you are travelling to an area where vaccination is recommended, such as sub-Saharan Africa. It's compulsory for pilgrims attending Hajj or Umrah. Without proof of vaccination you will not be allowed into Saudi Arabia," says Donovan. Meningitis vaccination is not available on the NHS, but other forms of travel vaccination are available.

Meningitis in the elderly

The main issue in this group is exposure to pneumococcal bacteria, which can cause meningitis as well as other life-threatening conditions. "The over-55s are at higher risk of infection with meningitis, as the immune system starts to deteriorate. Meningitis vaccination is available on the NHS for the over-65s," says Donovan. The PPV vaccine protects against 23 strains of pneumococcal bacteria. It's particularly recommended for those with chronic respiratory diseases and heart disease.

While it may not be as exciting as a trip to a theme park, arranging a day out to get your whole family vaccinated could help put everyone's mind at ease.
