How many infants born in the United States are breastfed? The CDC National Immunization Survey is a nationally representative sample of the U.S. population that provides the percent of U.S. children who are breastfed by birth year. Rates are provided on breastfeeding initiation, duration, and exclusivity.
Valtrex (valacyclovir) is an antiviral medication used to treat infections with: 1  herpes zoster (shingles), 2  herpes simplex genitalis (genital herpes), 3  and herpes labialis (cold sores).
However, as with cold sores and shingles, Valtrex is not a cure for genital herpes. Valtrex was approved for treating chickenpox in children based on studies of acyclovir (ZoviraxÂ®), a very similar medication. Other studies have shown that Valtrex (which the body transforms into acyclovir) is safe in children.
