Flu pandemic preparedness:  Vaccines offer best line of defence to protect the UK population

Paul Rayner, Chair of the UK Vaccine Industry Group (UVIG), today said that vaccines need to be the cornerstone of pandemic flu preparedness.

“UVIG supports the Government’s recognition that vaccination is the most effective way of limiting the potentially catastrophic impact of a flu pandemic. A comprehensive vaccination programme would be necessary to maximise our ability to prevent ill-health. Anti-viral drugs have a role to play during the time it would take to prepare the vaccines but it is vaccination that offers our best line of defence” he said.

Mr. Rayner added that industry is very keen to work closely with Government to ensure that the UK retains its high global standing as a nation preparing adequately for a flu pandemic.

“Currently, annual flu vaccination is recommended for those aged 65 and over and specific ‘at risk’ groups (see Note for Editors). However, extending the recommendation to include those aged between 50 to 65 years and children under 2 years of age would help increase annual uptake and allow manufacturers to invest in additional production capacity, helping ensure that demand in a pandemic year could be met.”

Flu vaccines are manufactured annually in line with the World Health Organisation’s recommendations on circulating flu virus strains. Inevitably, annual manufacturing capacity reflects usage in non-pandemic years. Europe , for example, has not seen a pandemic since the late 1960s. As a result, UVIG is concerned that there is insufficient capacity to meet the needs of the population during a flu pandemic.

“A flu pandemic occurs, on average, once every 25 years,” said Rayner. “As manufacturing capacity exists only to meet normal non-pandemic year demand, we urge the Government to support the industry in helping it increase capacity so that when the inevitable pandemic strikes we are better placed to protect the UK population. An important way the Government could help in this would be for the Department of Health to extend its current recommendations on which people should be given an annual flu vaccination.”

“With heightened concern that a flu pandemic is imminent, the Government needs to plan and make provision for sufficient doses of vaccine to be available to help protect the UK population. We hope to work collaboratively with the Department of Health on all issues affecting our preparedness to cope adequately with a flu pandemic.”

 

Notes

Flu vaccination in the UK

The Department of Health currently recommends flu vaccination for all people aged 65 and over and people of any age with:

    • Chronic respiratory disease, including asthma
    • Chronic heart disease, including angina
    • Chronic renal disease
    • Diabetes
    • Lowered immunity due to disease or treatment
    • Anyone living in a residential or nursing home

Approximately, 12 to 13 million doses of flu vaccine are supplied to the UK market each year.

In total, the EU has current capacity to manufacture approximately 90 million doses of flu vaccine each year.

How serious is flu?

  • In a usual (non-epidemic) year, death rates from influenza infection or its complications average 3,000 to 4,0001. 
  • During epidemics, this level is much higher - for example during the epidemic of 1989-90 there were almost 30,000 excess deaths in the UK attributable to flu2
  • The number of people affected in a pandemic year is hard to predict but would be significantly greater.
  • Deaths as a direct result of flu infection are often under-reported as flu is often not documented as the cause of death on the death certificate. Instead, the death may be attributed to its consequences e.g. myocardial infarction (heart attack) or pneumonia.
  • Every year episodes of flu with cases numbering between 30 and 200 per 100,000 of the population are usual3.
  • During the epidemic of the winter of 1989/90 weekly consultation rates for influenza-like illness reached a peak of 583 cases per 100,000 population4. In recent years, the highest rates observed were in 2001 when a peak of 69 cases per 100,000 occurred in mid-February4.

Government announces stockpiling of anti-viral drug Tamiflu® (oseltamivir) to prepare for the next influenza pandemic

Welwyn Garden City, Tuesday 1st March 2005 : The Department of Health today launched its influenza pandemic plan: a guideline to assist health authorities and other agencies to prepare their contingency arrangements in the event of a national influenza outbreak. The stockpiling of 14.6 million courses of the oral antiviral Tamiflu (oseltamivir), active against all strains of influenza viruses including avian H5N1 which is currently circulating in the Far East and has killed over 40 people, is included as a critical element of the plan. Tamiflu is an antiviral drug that can treat and prevent influenza, but it is not a vaccine.

The establishment of national stockpiles of antiviral treatments was recommended by the World Health Organisation as part of its global pandemic preparedness guidelines, which was launched in 1999. [i] The WHO estimated that, in the event of a pandemic, it could take six to eight months to develop a new vaccine that is effective against the circulating influenza strain, and recognised that supplies of antivirals will be critical to manage the outbreak whilst a vaccine is being developed to prevent the spread of the virus.[ii].

 “The stockpiling of oseltamivir, that can both prevent the spread of influenza and reduce the risk of complications such as pneumonia and hospitalisations in those who have already contracted the virus, is a welcome addition to the treatment options available to us when the pandemic hits,” said Professor Jo hn Oxford, St Bartholomew’s and The London Hospital, Queen Mary’s School of Medicine and Dentistry, London.

Roche is pleased at the progress that has been made with the publication of the UK plan, and will continue to work as a responsible partner with the Department of Health to assist with the implementation of the pandemic plan. Roche anticipate that the UK Department of Health stockpile of Tamiflu will be built up over the next two years  

Professor Oxford concluded, “Since it is not a case of if the next influenza pandemic occurs, but when, I welcome the Department of Health’s pandemic plan. By planning carefully and effectively now, we can prepare to manage the impact of the pandemic. ”

Notes to Editors

About Influenza

Influenza is a highly contagious viral infection which can have very serious complications, especially in ‘at-risk’ populations. These groups are more likely than the general population to experience complications following influenza, such as bronchitis, pneumonia, otitis media (ear infection) and sinusitis that may require hospitalisation.[v] The Department of Health has noted that peaks of winter mortality closely follow the pattern of influenza activity. It estimates that there may be as many as 12,000 deaths over and above the expected mortality rate each winter.[vi]

About Influenza Pandemics

According to the World Health Organisation (WHO), the body responsible for international influenza surveillance and planning, a pandemic occurs when a new strain of the virus appears against which the human population has no immunity, resulting in several, simultaneous epidemics worldwide with enormous numbers of deaths and illness.2

Influenza pandemics occur approximately every 40 years, and experts caution that it is a case of when, not if, the next pandemic will strike. Previous pandemics have spread quickly and resulted in worldwide loss of life. The most deadly of these in recent history was the Spanish flu outbreak of 1918, which claimed the lives of 30 million people. The mildest pandemic of the past century, which took place in Hong Kong in 1968, still claimed one and a half million lives in six weeks.

About Tamiflu

Tamiflu is the latest of the neuraminidase inhibitor (NI) class of medicines designed specifically to prevent the influenza virus from spreading and infecting other cells. In adults, if taken within 36 hours of the onset of influenza, Tamiflu reduces the severity of symptoms by up to 40% and the duration of illness by 30%.3 Tamiflu has been shown to significantly reduce the incidence of influenza-associated chest infections requiring antibiotic therapy by over 50% in adults.3 Treatment with Tamiflu also significantly reduce hospitalisations.[vii]

Tamiflu is also effective in children, reducing the severity and duration of influenza symptoms.[viii] The incidence of associated otitis media is reduced by 44% with Tamiflu as compared to standard care.12 In addition, Tamiflu prevented influenza developing in 89% of adults and adolescents who have been in close contact with influenza-infected patients.[ix]

Tamiflu has a shelf life of 5 years.

Tamiflu was launched in the UK in January 2003. Tamiflu has been used to treat around 40 million influenza sufferers in over 40 countries worldwide.
