Health Protection Agency

Health Protection Agency is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Health Protection Agency rather than just read about it. In short: The Health Protection Agency (HPA) was a non-departmental public body in England. It was set up by the UK government in 2003 to protect the public from threats to their health from infectious diseases and environmental hazards.

Reference excerpt

The Health Protection Agency (HPA) was a non-departmental public body in England. It was set up by the UK government in 2003 to protect the public from threats to their health from infectious diseases and environmental hazards. The HPA's role was to provide an integrated approach to protecting public health in the UK. It did this by providing advice and information to the general public, health professionals and local government, and by providing emergency services, support and advice to the National Health Service (NHS) and the Department of Health. The HPA also played a lead role in helping prepare for new and emerging health threats, such as bioterrorism or emerging virulent disease strains. There were four HPA centres – at Porton Down in Salisbury, Chilton in Oxfordshire, South Mimms in Hertfordshire, and Colindale in NW London. In addition, the HPA had regional laboratories across England and administrative headquarters in Central London. On 1 April 2013, the HPA minus the South Mimms site became part of Public Health England, a new executive agency of the Department of Health (DoH). The National Institute for Biological Standards and Control (NIBSC) located in South Mimms was merged with the Medicines and Healthcare products Regulatory Agency (MHRA).

History The Health Protection Agency (HPA) was originally established as an NHS special health authority in 2003. On 1 April 2005, the Agency became a non-departmental public body, with the National Radiological Protection Board (NRPB) being merged into the organisation at the same time.

The origins of the HPA's largest facility in Porton Down can be traced back to 1940, when Porton had a highly secret and independent 'Biology Department' under the Ministry of Defence to study biological warfare and defence against it. By 1946 it was called the 'Microbiological Research Department', and from 1951 the 'Microbiological Research Establishment', with research becoming increasingly defensive and civilian in nature. Total civilian control was established by moving biological defence work to the Chemical Defence Establishment (now dstl), and renaming the facility from 1 April 1979 as the Centre for Applied Microbiology and Research (CAMR) within the Public Health Laboratory Service (PHLS). In April 1994, CAMR moved from PHLS centre to the Microbiological Research Authority (MRA), reporting to the Department of Health and continuing the programme in civil microbiological research started in 1979. Microbiology Services remained the biggest of the four Divisions within the HPA with 1800 staff, consisting of laboratory groups from the Centre for Emergency Preparedness and Response, the Centre for Infections, eight regional microbiology laboratories and 37 collaborating hospital laboratories. Together, these laboratories provided frontline diagnostic and public health microbiology services to NHS trusts and HPA health protection units. Its remit included infectious disease surveillance, providing specialist and reference microbiology and microbial epidemiology, coordinating the investigation and cause of national and uncommon outbreaks, helping advise government on the risks posed by various infections and responding to international health alerts. In addition, both basic and applied research was undertaken to understand infectious diseases, and the group manufactured a number of healthcare products including vaccines and therapeutics. For instance, the HPA was the sole licensed manufacturer of anthrax vaccine in the UK.

After dissolution On 1 April 2013, the Health Protection Agency was merged into Public Health England (PHE), an executive agency of the Department of Health. In August 2020, the UK Government announced that PHE would be replaced by a new organisation, the UK Health Security Agency (UKHSA), which formally launched on 1 April 2021. The health improvement functions of PHE were transferred to the Office for Health Improvement and Disparities (OHID), also within the Department of Health and Social Care.

Funding HPA was accountable to the UK Secretary of State for Health, and was funded primarily by Government Grant in Aid. Other income was received from the NHS, commercial activities, grants, and other sources. HPA’s income for the fiscal year ending 31 March 2008, was £160.2 million from Revenue Government financing plus £109.2 million total operating income. Total average staff numbers for that year, including secondments and agency staff, were 3,394 staff.

Organisation

Following consultation during April 2010, the HPA was organised into four groups: Microbiology Services, Health Protection Services, Biological Standards and Control, and the Centre for Radiation, Chemical and Environmental Hazards.

Worked examples

Example 1 — a first encounter with Health Protection Agency

Start with the simplest possible case. Write down what Health Protection Agency claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Health Protection Agency before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Health Protection Agency ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Health Protection Agency

In research: Health Protection Agency appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Health Protection Agency in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Health Protection Agency is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2003 establishments in England, Defunct public bodies of the United Kingdom, Department of Health and Social Care, so understanding it makes those chapters shorter.
In everyday life: Look for Health Protection Agency outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
