| Question | Answer |
| TRUE/FALSE? A. Measles vaccination may be administered before 12 months of age. | True. The measles vaccination is ideally given at 12 months or there after. It may be given earlier, for example during an outbreak of measles or in developing countries where measles is a common illness. However if given earlier than 12 months of age a second dose is recommended after 12 months of age, taking into consideration poor vaccine response prior to 12 months of age due to interference by maternal antibodies. |
| TRUE/FALSE? B. The immune system responds to polysaccharide vaccines from birth. | False. Polysaccharide vaccines are not very immunogenic in children under two years of age and are therefore not very effective in this age group. |
| TRUE/FALSE? C. Conjugate vaccines are immunogenic under 2 years old and require several doses. | True. Conjugate vaccines are immunogenic under 2 years old and require several doses. |
| TRUE/FALSE? D. The MMRV vaccine is given at 24 months as part of the Australian immunisation schedule. | False. The MMRV vaccine(measles, mumps, rubella and varicella vaccine) has recently been added to the Australian immunisation schedule, to be administered at 12 months and again at 18 months of age. |
| TRUE/FALSE? E. Adolescents are susceptible to pertussis. | True. Adolescents are susceptible to pertussis and may transmit the disease to infants. School age children/adolescents should have a booster dose of dTpa vaccine. |
| TRUE/FALSE? F. The highest notification rates for pertussis is in infants under one year old. | True. The highest notification rates for pertussis is in infants under one year old with rates of approximately 100 per 100 000. The common source of infection is parents and/or grandparents who should therefore ideally be immunised against pertussis. |
| TRUE/FALSE? G. Varicella vaccine has 100% efficacy. | False. Varicella vaccine has a 70 to 90% efficacy rate. |
| TRUE/FALSE? H. Varicella vaccination is not required in adolescents and young adults. | False. Adolescents and young adults who do not have a history of varicella infection should be immunised (if they had a dose of varicella vaccine at 18 months, they should receive a booster dose) as chicken pox can have serious complications in adolescents and young adults. |
| TRUE/FALSE? I. House hold contacts of immuno-suppressed persons should NOT receive varicella vaccine. | False. House hold contacts of immuno-suppressed persons should receive varicella vaccine even though it is a live vaccine as it can aid in preventing infection being brought into the household. |
| TRUE/FALSE? J. Influenza vaccine is recommended in children under five years of age. | True. Influenza vaccine is recommended in children aged between six months and five years (2 doses 1 month apart the first time), although it is not a part of the Australian immunisation schedule. |
| TRUE/FALSE? K. The HPV vaccine is currently being administered to females aged 10-13 years. | True. The HPV (Human Papilloma Virus) vaccine is being administered to females aged 10-13 years. There are no studies on the clinical effectiveness in preadolescence as collection of genital specimens is not appropriate. It is likely that the vaccine will be most effective when given prior to onset of sexual activity. |
