Universities of Leicester and Nottingham project could hold key to reducing spread of meningitis and septicaemia

A campaign targeted at students arriving at university for the first time could hold the key to reducing the spread of meningitis and septicaemia, say researchers at the Universities of Leicester and Nottingham.

In a paper published in the academic journal Public Health, the researchers show how a campus-based vaccination campaign was successful in ensuring that almost three-quarters of students arriving at Nottingham were immunised against the potentially deadly disease.

The approach was so successful it has now been highlighted as an example of best practice by Public Health England in a report advising on the prevention and management of meningitis and septicaemia in higher education.

Dr David Turner in the University’s School of Life Sciences said:  “It is really important to offer the MenACWY vaccine to first year university students to prevent cases of meningitis in this at-risk group”.

Dr Chris Bayliss from the University of Leicester's Department of Genetics said: "A high uptake of the MenACWY vaccine will help to protect first year university students and the wider community against meningitis and septicaemia caused by meningococcal bacteria particularly this new hypervirulent MenW strain."

In England, cases of meningitis caused by the Meningitis W (MenW) bacteria have been rapidly increasing since 2009 due to the emergence of a highly aggressive ST-11 strain. The illnesses associated with this strain are often severe with a frequent requirement for treatment in intensive care and a higher death rate than other meningococcal strains.

Symptoms of infection range from the lethargy, mild fever, headaches and vomiting seen with other meningococcal strains to unusual presentations such as  joint infections, pneumonia, epiglottitis (a dangerous swelling around the "lid" that covers the windpipe), and gastrointestinal symptoms. These latter symptoms can occur without the characteristic non-blanching rash and may rapidly become more severe and have led to deaths in a number of cases.

In response, Public Health England introduced a programme of immunisation offering vaccination against four different types of Meningitis – A, C, W and Y - to all adolescents and young adults aged between 14 and 18 years of age, as well as first-year university students including international and mature students up to the age of 25.

The aim was to disrupt the transmission of the dangerous MenW bacteria and to prevent its further spread to at-risk groups of people within the wider population.

Higher rates of transmission of the meningitis bacteria occur in students during the first year of university and, as students tend to travel frequently around the country to return home or to visit friends, there is a risk they could spread the disease to other communities throughout the UK.

The academics at Nottingham, working in collaboration with Dr Bayliss, studied the uptake of the ACWY vaccine in first-year students.

During registration at the university between 17th and 23rd September 2015, as part of standard clinical practice, each student was interviewed by University of Nottingham Health Service healthcare professionals to establish whether students had been vaccinated before arriving at university and to record their details on the UNHS registration database.

Students who said they hadn’t been vaccinated were offered an immediate free vaccination.

Searches of the UNHS registration database were later performed to determine vaccination coverage for first-year students before arrival at Nottingham, as well as a smaller group of international students who were less likely to have received the vaccine in their home country before arriving at university in the UK.

The searches revealed that just 31 per cent of the students had been previously vaccinated – coverage that would be potentially too low to significantly reduce the spread of meningitis.

However, following the local campaign by the healthcare professionals at UNHS, that figure rose to a far healthier 71 per cent.

Dr Bayliss commented: “Vaccination is highly effective at preventing meningitis, septicaemia and the other infections caused by meningococci. Our study shows that offering MenACWY vaccination as students arrive at a University is a really effective way of maximising protection of this vulnerable age group.”

Dr Turner added: “The significant boost in coverage following the vaccine campaign at registration at the University of Nottingham demonstrates the importance of offering vaccination at enrolment in tertiary educational establishments and suggests that rolling out this strategy more widely could significantly improve vaccine coverage in this age group. The campus-based mass vaccination campaign delivered during the registration period also provided significant logistical advantages compared with offering a large number of individual appointments.”

The researchers also noted that some unvaccinated students declined vaccination suggesting that further advertising of the national campaign could be necessary to raise awareness of the vital need for the MenACWY vaccine.”

In line with most other universities, the University of Leicester uses advertising to raise awareness of meningitis and to recommend vaccination prior to starting or on arrival at the campus.

In addition, all new students are contacted prior to arrival at the University of Leicester with information about the need for the MenACWY vaccine and how to get vaccinated. This includes their local GP before leaving for University or with one of the local Health Centre’s who work closely with the University to support Student health and wellbeing.

Staff from the Health Centre are present on campus through the registration period to make it easier for students to register for health care and at the same time information is provided about how to make an appointment for the MenACWY vaccine.

The campaign at the University of Nottingham was featured as a case study in the recent publication Guidance on the Prevention and Management of Meningococcal Meningitis and Septicaemia in Higher Education Institutions issued by Public Health England.

The report recommended that the Nottingham example may be helpful in identifying ways in which Higher Education Institutions can play an active role in improving awareness and promoting vaccination uptake amongst students.
