If a healthy 6-year-old child (who does not have evidence of immunity to varicella) was exposed to a confirmed case of varicella 2 days ago, the correct action to take is:

a) advise the parents that the child will likely develop varicella.
b) administer antiviral medication (or refer the child to a health care provider who can administer antiviral medication).
c) administer vzig (or refer the child to a health care provider who can vzig).
d) administer varicella vaccine.

Administer varicella vaccine to the health 6-year old child (who does not have evidence of immunity to varicella) was exposed to a confirmed case of varicella 2 days ago.
