susceptible person exposed fewer than 6 days previously,
for susceptible household contacts of measles patients,
particularly contacts <1 year and pregnant women without

Which of the following statements is correct regarding anti-D immunoglobulin?
Your Answer: It is administered as part of routine antenatal care for rhesus-negative mothers.
Explanation:In all non-sensitised pregnant women who are RhD-negative, it is recommended that routine antenatal anti-D prophylaxis is offered. Even if there is previous anti-D prophylaxis, use of routine antenatal anti-D prophylaxis should be given for a sensitising event early in the same pregnancy. Postpartum anti-D prophylaxis should also be given even if there has been previous routine antenatal anti-D prophylaxis or antenatal anti-D prophylaxis for a sensitising event in the same pregnancy.

Question 4
Incorrect

Which of the following is an example of a vaccine produced by recombinant DNA technology:
Your Answer: MMR
Correct Answer: Hepatitis B
Explanation:Hepatitis B vaccines are prepared from the viral surface antigen. The recombinant vaccine is now the most widely used vaccine and induces a sufficient antibody response in 90% of individuals.
Indications for hepatitis B vaccination include:
All health care professional’s
Other professions with occupational risks (foster carers, staff of custodial institutions, morticians etc)
Babies of mothers with hepatitis B during pregnancy
Close family contacts of a case or carrier
IV drug abusers
Individuals with haemophilia
Individuals with chronic renal failure
Sex workers and individuals with frequently changing sexual partners
The vaccine should be stored between 2 and 8 degrees C as freezing destroys its efficacy. The vaccine is administered intramuscularly, either into the deltoid region (preferred) or anterolateral thigh. The buttock should be avoided as it reduces the efficacy of the vaccine.
The standard regime is to give 3 doses of the vaccine, the 1stand 2ndone month apart and the 2ndand 3rdsix months apart. Antibody titres should be tested 2 to 4 months after the primary course.
A peak titre above 100 mIU/ml is regarded as a good response and implies long-term immunity. A peak titre between 10-100 mIU/ml is regarded as a low response and a peak titre of less than 10mIU/ml is regarded as a poor response.
There is no substantiated association between hepatitis B vaccination and Guillain-Barre syndrome. -
