Nasal Flu Vaccine: From 1 Different Sources

(in Britain), a vaccine currently offered to all 2- and 3-year-olds in the form of a spray into each nostril. It contains live forms of the influenza virus that have been attenuated (weakened). The vaccine stimulates the immune system but does not cause disease in healthy people.

Vaccine

A preparation of dead particulate or weakened bacteria or viruses prepared for injection into the body so that antibodies are formed to prevent disease (eg polio). Detoxi fied but genetically potent toxins (called toxoids) can also be used (e.g. tetanus and diphtheria)... vaccine

Dpt Vaccine

Often called the TRIPLE VACCINE, the injections produce immunity against DIPHTHERIA, whooping cough (PERTUSSIS) and TETANUS. The vaccine is given as a course of three injections to infants around the ages of two, three and four months, together with haemophilus in?uenza B and meningococcal C vaccine as well as oral polio vaccine. A booster injection is given at school entry (see schedule in IMMUNISATION).... dpt vaccine

Mmr Vaccine

A combined vaccine o?ering protection against MEASLES, MUMPS and RUBELLA (German measles), it was introduced in the UK in 1988 and has now replaced the measles vaccine. The combined vaccine is o?ered to all infants in their second year; health authorities have an obligation to ensure that all children have received the vaccine by school entry – it should be given with the pre-school booster doses against DIPHTHERIA, TETANUS and POLIOMYELITIS, if not earlier – unless there is a valid contra-indication (such as partial immunosuppression), parental refusal, or evidence of previous infection. MMR vaccine may also be used in the control of measles outbreaks, if o?ered to susceptible children within three days of exposure to infection. The vaccine is e?ective and generally safe, though minor symptoms such as malaise, fever and rash may occur 5–10 days after immunisation. The incidence of all three diseases has dropped substantially since MMR was introduced in the UK and USA.

A researcher has suggested a link between the vaccine and AUTISM, but massive studies of children with and without this condition in several countries have failed to ?nd any evidence to back the claim. Nonetheless, the publicity war has been largely lost by the UK health departments so that vaccine rates have dropped to a worryingly low level.

Nasal Congestion

The nose and nasal sinuses (see SINUS) produce up to a litre of MUCUS in 24 hours, most of which enters the stomach via the NASOPHARYNX. Changes in the nasal lining mucosa occur in response to changes in humidity and atmospheric temperature; these may cause severe congestion, as might an allergic reaction or nasal polyp.

Treatment Topical nasal decongestants include sodium chloride drops and corticosteroid nasal drops (for polyps). For commoncold-induced congestion, vapour inhalants, decongestant sprays and nasal drops, including EPHEDRINE drops, are helpful. Overuse of decongestants, however, can produce a rebound congestion, requiring more treatment and further congestion, a tiresome vicious circle. Allergic RHINITIS (in?ammation of the nasal mucosa) usually responds to ipratropium bromide spray.

Systemic nasal decongestants given by mouth are not always as e?ective as topical administrations but they do not cause rebound congestion. Pseudoephedrine hydrochoride is available over the counter, and most common-cold medicines contain anticongestant substances.... nasal congestion

Salk Vaccine

A vaccine obtained by treating the POLIOMYELITIS virus with formalin. This prevents the virus from causing the disease but allows it to stimulate the production of ANTIBODIES. Salk vaccine is given by injection and protects the recipient against the disease. (See also IMMUNISATION.)... salk vaccine

Tab Vaccine

A combined VACCINE administered to produce IMMUNITY against typhoid and paratyphoid A and B (see ENTERIC FEVER). (See also IMMUNISATION.)... tab vaccine

Triple Vaccine

Also known as DPT vaccine, this is an injection that provides IMMUNITY against DIPHTHERIA, pertussis (whooping-cough) and TETANUS. It is given as a course of three injections at around the ages of two, three and four months. A booster dose of diphtheria and tetanus is given at primary-school age. Certain infants – those with a family history of EPILEPSY, or who have neurological disorders or who have reacted severely to the ?rst dose – should not have the pertussis element of DPT. (See MMR VACCINE; IMMUNISATION.)... triple vaccine

Hib Vaccine

A vaccine administered routinely at 2, 3, and 4 months of age to provide immunity to the bacterium HAEMOPHILUS INFLUENZA type b (Hib).

Before the vaccine was generally available, Hib infection was a common cause of bacterial meningitis and epiglottitis in children.... hib vaccine

Bcg Vaccine

BCG (Bacillus Calmette-Guérin) vaccine, which was ?rst introduced in France in 1908, is the only vaccine that has produced signi?cant immunity against the tubercle bacillus (see TUBERCULOSIS) and at the same time has proved safe enough for use in human subjects. BCG vaccination is usually considered for the following groups of people. (1) Schoolchildren: the routine programme in schools usually covers children aged between ten and 14. (2) Students, including those in teacher training colleges. (3) Immigrants from countries with a high prevalence of tuberculosis (TB). (4) Children and newborn infants born in the UK to parents from Group 3, or other newborns at parents’ request. (5) Health workers, such as nurses, and others likely to be exposed to infection in their work. (6) Veterinary workers who handle animals susceptible to TB. (7) Sta? of prisons, residential homes and hostels for refugees and the homeless. (8) Household contacts of people known to have active TB and newborn infants in households where there is a history of the disease. (9) Those staying for more than one month in high-risk countries.

A pre-vaccination tuberculin test is necessary in all age-groups except newborn infants, and only those with negative tuberculin reactions are vaccinated. Complications are few and far between. A local reaction at the site of vaccination usually occurs between two and six weeks after vaccination, beginning as a small papule that slowly increases in size. It may produce a small ulcer. This heals after around two months, leaving a small scar. (See IMMUNITY; TUBERCULIN.)... bcg vaccine

Sabin Vaccine

Introduced in 1962, the attenuated live oral vaccine (Sabin) against POLIOMYELITIS replaced the previous inactivated vaccine introduced in 1956 (see SALK VACCINE).... sabin vaccine

Yellow Fever Vaccine Is Prepared From

chick embryos injected with the living, attenuated strain (17D) of pantropic virus. Only one injection is required, and immunity persists for many years. Re-inoculation, however, is desirable every ten years. (See YELLOW FEVER.)

Haemophilus vaccine (HiB) This vaccine was introduced in the UK in 1994 to deal with the annual incidence of about 1,500 cases and 100 deaths from haemophilus MENINGITIS, SEPTICAEMIA and EPIGLOTTITIS, mostly in pre-school children. It has been remarkably successful when given as part of the primary vaccination programme at two, three and four months of age – reducing the incidence by over 95 per cent. A few cases still occur, either due to other subgroups of the organism for which the vaccine is not designed, or because of inadequate response by the child, possibly related to interference from the newer forms of pertussis vaccine (see above) given at the same time.

Meningococcal C vaccine Used in the UK from 1998, this has dramatically reduced the incidence of meningitis and septicaemia due to this organism. Used as part of the primary programme in early infancy, it does not protect against other types of meningococci.

Varicella vaccine This vaccine, used to protect against varicella (CHICKENPOX) is used in a number of countries including the United States and Japan. It has not been introduced into the UK, largely because of concerns that use in infancy would result in an upsurge in cases in adult life, when the disease may be more severe.

Pneumococcal vaccine The pneumococcus is responsible for severe and sometimes fatal childhood diseases including meningitis and septicaemia, as well as PNEUMONIA and other respiratory infections. Vaccines are available but do not protect against all strains and are reserved for special situations – such as for patients without a SPLEEN or those who are immunode?cient.... yellow fever vaccine is prepared from

Nasal Discharge

The emission of fluid from the nose. Nasal discharge is commonly caused by inflammation of the mucous membrane lining the nose and is often accompanied by nasal congestion. A discharge of mucus may indicate allergic rhinitis, a cold, or an infection that has spread from the sinuses (see sinusitis). A persistent runny discharge may be an early indication of a tumour (see nasopharynx, cancer of).

Bleeding from the nose (see nosebleed) is usually caused by injury or a foreign body in the nose.

A discharge of cerebrospinal fluid from the nose may follow a fracture at the base of the skull.... nasal discharge

Nasal Obstruction

Blockage of the nasal passage on 1 or both sides of the nose.

The most common cause of nasal obstruction is inflammation of the mucous membrane lining the passage (see nasal congestion).

Other causes include deviation of the nasal septum, nasal polyps, a haematoma (a collection of clotted blood) usually caused by injury, and, rarely, a cancerous tumour.

In children, enlargement of the adenoids is the most common cause of nasal obstruction.... nasal obstruction

Nasal Polyp

A growth in the lining of the nose, usually attached by a small stalk.

Most nasal polyps are noncancerous, but they may need to be removed if they cause nasal obstruction.... nasal polyp

Nasal Septum

The dividing partition inside the nose. The nasal septum consists of cartilage at the front and bone at the rear, both of which are covered by mucous membrane.

Disorders include a deviated septum (twisting of the septum to one side), which may be present from birth or caused by injury. Surgery may be needed if breathing is obstructed.

Injury may also cause a haematoma (a collection of clotted blood) to form between the cartilage of the septum and the wall of one nasal cavity. A haematoma may obstruct breathing and may become infected, causing an abscess that could require surgical drainage.

Rarely, a hole may be eroded in the nasal septum by tuberculosis, syphilis, Wegener’s granulomatosis, or as a result of sniffing cocaine.... nasal septum

Menacwy Vaccine

a vaccine that provides protection against four different strains (A, C, W, and Y) of the bacterium Neisseria meningitidis (the meningococcus) that causes *meningitis and septicaemia. It also prevents the carriage of the bacteria in the nose and back of the throat. In Britain it is offered to children aged 14 years and students going to college and university for the first time.... menacwy vaccine

Meningitis B Vaccine

(MenB) a vaccine that provides protection against the B strain of the bacterium Neisseria meningitidis (the meningococcus), which accounts for more than 90% of meningococcal infections in young children. The MenB vaccine is offered to all babies with their primary *immunizations at 2 and 4 months of age and as a booster at 12 months. See meningitis.... meningitis b vaccine

Meningitis C Vaccine

(MenC) a vaccine that provides protection against the C strain of the bacterium Neisseria meningitidis (the meningococcus), which accounts for approximately 50% of all cases of meningococcal meningitis and tends to occur in clusters. Owing to the success of the MenC vaccination programme begun in 1999 there have been almost no recent cases of meningitis C disease in babies and young children in the UK. The vaccine was previously offered to all babies at 12 weeks of age but is now given at 12 months as part of Hib/MenC vaccine and at 14 years as the MenACWY vaccine.... meningitis c vaccine

Nasal Bone

either of a pair of narrow oblong bones that together form the bridge and root of the nose. See skull.... nasal bone

Nasal Bridle

a fixation device to prevent patients pulling out *nasogastric (NG) tubes. Two tiny catheter-mounted magnets are inserted either side of the nasal septum to meet in the nasopharyngeal space. This leaves tapes exiting from each nostril. A clip then secures the tapes and NG tube together.... nasal bridle

Nasal Cavity

the space inside the nose that lies between the floor of the cranium and the roof of the mouth. It is divided into two halves by a septum: each half communicates with the outside via the nostrils and with the nasopharynx through the posterior nares.... nasal cavity

Nasal Concha

(turbinate bone) any of three thin scroll-like bones that form the sides of the *nasal cavity. The superior and middle nasal conchae are part of the *ethmoid bone; the inferior nasal conchae are a separate pair of bones of the face. See skull.... nasal concha

Pneumococcal Vaccine

a vaccine that protects against infection by the bacterium *Streptococcus pneumoniae, which can cause serious diseases, including pneumonia, septicaemia, and *meningitis. Children under 2 years of age and adults over 65 years are at particular risk. Since September 2006, the pneumococcal vaccine has become part of the childhood *immunization programme. It is also offered to people over the age of 65 as a single vaccination that will protect for life.... pneumococcal vaccine

Rotavirus Vaccine

an oral vaccine against *rotavirus infection. In Britain it is offered to babies at 2 and 3 months of age, alongside their other childhood vaccinations.... rotavirus vaccine

sabin Vaccine

an oral vaccine against (E954) poliomyelitis, prepared by culture of the virus under special conditions so that it loses its virulence (i.e. it becomes attenuated) but retains its ability to stimulate antibody production. [A. B. Sabin (1906–93), US bacteriologist]... sabin vaccine
