True or False
All vaccines , including live-virus vaccines, can be given to women who are breastfeeding.
True
True or False
Infants under one year of age are most frequently exposed in daycare settings.
False
Infant exposures to pertussis 32% of the time come from mothers and 75% of exposures are familial (siblings, grandparents, etc.).
True or False
The best time to immunize pregnant women with MMR, Tdap, and Varicella vaccines is postpartum in the hospital.

Optimally a woman should be vaccinated prior to pregnancy, but when an unimmunized pregnant woman’s presents to office, these vaccines should be given postpartum.
True or False
Pregnant women are at 4x the risk of complications and hospitalizations due to the normal seasonal flu and were 6x more likely to die than the general population due to H1N1 infection in 2009-10. Therefore, it is advised that pregnant women receive the TIV influenza vaccine.
True
True or False
Women who have been exposed to one HPV genotype can still benefit from HPV vaccines because they will be protected against other genotypes and therefore should receive the HPV vaccine.
True
How often does Rapid Cycle Analysis through the Vaccine Safety Datalink occur in order to compare adverse events in people who have received a vaccine as compared to those in a similar group who have not?
Weekly
CDC Guidelines on immunizations indicate that it is safe to give inactivated vaccines on the usual schedule but live virus vaccines should be withheld a minimum of three months following completion of radiation therapy.
True or False
True
True or False:
There are no concerns that radiation therapy may affect the efficacy of immunizations.
False
Because these concerns exist, immunizations during radiation therapy should be avoided if possible and deferred until three months after radiation therapy has been completed.

Since MMR is a live-virus vaccine, a vaccine recipient could shed the virus and infect another person. This is a concern for a household member who is immunosuppressed.
True (with caveat)
Although the above statement is true, no unusual adverse events have been reported in immunosuppressed individuals receiving inactivated vaccines.
Which flu vaccine should be used in an immunocompromised patient, TIV or LAIV?
TIV
Persons with altered immunocompromised are generally advised to receive which vaccine according to CDC guidelines?
- TIV
- Polysaccharide-based vaccines (I.e. PCV, PPV, MCV4, MPSV, and Hob vaccines)
This recommendation is based on the facts of demonstrated effectiveness and an increased risk for disease if the vaccines are withheld.
