Immunisation and Prophylaxis Flashcards
What is the antibody response to infection?
Immunological memory results in a fast, high response to prevent infection again
What types of infection are there?
First year lectures
Types of vaccine
Live attenuated Inactivated (killed) Detoxified exotoxin Subunit of micro-organism -Purified microbial products -Recombinant
Live attenuated vaccines
Measles, mumps, rubella (MMR) BCG Varicella-zoster virus Yellow fever Smallpox Typhoid (oral) Polio (oral) Rotavirus (oral)
Inactivated vaccines
Polio Hepatitis A Cholera (oral) Rabies Japanese encephalitis Tick-borne encephalitis Influenza
How to detoxified exotoxin vaccines work?
Toxin is treated with formalin to form toxoid
eg diphtheria, tetanus
Subunit vaccines
Pertussis (acellular) Haemophilus influenzae type b Meningococcus (group C) Pneumococcus Typhoid Anthrax Hepatitis B
What is the 6 in 1 vaccine?
Diphtheria Tetanus Pertussis Polio Hib HBV
Childhood immunisation schedule 1
6 in 1 vaccine
2 months => + pneumococcal conjugate + rotavirus + Men B
3 months => + rotavirus
4 months => + pneumococcal conjugate + Men B
Childhood immunisation schedule 2
1 year => Hib/Men C+ MMR + pneumococcal conjugate + men B
2-8 years => influenza nasal
3-5 years => 4 in 1 booster + MMR
Girls, 12-13 years => HPV
14 years => 3 in 1 booster + Men ACWY
Immunisations for special patient and occupational groups
BCG Influenza Pneumococcal Hepatitis B Varicella-zoster Herpes-zoster
Pneumococcal vaccinations
Pneumococcal conjugate polysaccharide vaccine (13 serotypes) - part of childhood immunisations
Pneumococcal polysaccharide vaccine (23 serotypes) - for those at increased risk of pneumococcal infection
Passive immunisation
Human normal immunisation
Disease specific immunoglobulin (post-exposure)
Human normal immunisation
Contains antibodies against hepatitis A, rubella, measles
Used in immunoglobulin deficiencies
Treatment of some autoimmune disorders, e.g. myasthenia gravis
Disease specific immunoglobulin
Hepatitis B Ig Rabies Ig Tetanus anti-toxin Ig Varicella zoster (chickenpox) Ig Diphtheria anti-toxin Ig (horse) Botulinum anti-toxin Ig
