Vaccinations Flashcards
What is an inactivated vaccine?
Involves giving a killed version of the pathogen.
They cannot cause an infection and are safe for immunocompromised patients, although they may not have an adequate response.
Give 4 examples of inactivated vaccines
1) Polio
2) Flu vaccine
3) Hep A
4) Rabies
What are subunit or conjugate vaccines?
Subunit and conjugate vaccines only contain parts of the organism used to stimulate an immune response.
They also cannot cause infection and are safe for immunocompromised patients.
What are 7 examples of subunit and conjugate vaccines?
1) Pneumococcus
2) Meningococcus
3) Hepatitis B
4) Pertussis (whooping cough)
5) Haemophilus influenza type B
6) Human papillomavirus (HPV)
7) Shingles (herpes-zoster virus)
What are live attenuated vaccines?
Live attenuated vaccines contain a weakened version of the pathogen.
They are still capable of causing infection, particularly in immunocompromised patients.
Give 5 examples of live attenuated vaccines
1) MMR
2) BCG: contains a weakened version of tuberculosis
3) Chickenpox: contains a weakened varicella-zoster virus
4) Nasal influenza vaccine (not the injection)
5) Rotavirus
What does the BCG vaccine contain?
A weakened version of TB
What are toxin vaccines?
Contain a toxin that is normally produced by a pathogen.
They cause immunity to the toxin and not the pathogen itself.
Give 2 examples of toxin vaccines
1) Diptheria
2) Tetanus
What does the term ‘valency’ in vaccinology refer to?
This denotes the number of distinct antigenic components or serotypes a vaccine can protect against.
Essentially, it specifies the extent of a vaccine’s antigenic reach.
What is a monovalent vaccine?
Contain a singular antigenic component, conferring immunity against one strain or subtype of a pathogen
E.g. measles vaccine
What is a multivalent or polyvalent vaccine?
These vaccines comprise multiple antigenic components, safeguarding against various strains or subtypes of a pathogen or, occasionally, multiple pathogens.
E.g. the quadrivalent influenza vaccine, protective against four distinct virus strains.
Vaccination schedule: 2 months old?
1) 6 in 1 (1st dose)
2) Rotavirus vaccine (1st dose)
3) Meningitis B vaccine
What does the 6 in 1 vaccine contain?
1) diptheria
2) tetanus
3) pertussis
4) polio
5) haemophilus influenzae type B (Hib)
6) hepatitis B
Vaccination schedule: 3 months old?
1) 6 in 1 (2nd dose)
2) Pneumococcal (PCV) vaccine (13 different serotypes)
3) Rotavirus vaccine (2nd dose)
