Generally, over how long a time does an infant (who didn’t receive antibodies as a fetus) need to be breast fed for in order to receive protection?
Breastfeeding is strongly encouraged with infants up to age 6-12 months old. In addition to its nutritional value, protective antibodies are passed along to the infant. While these antibodies can provide partial protection, it is still recommended that all Canadians over 6 months old receive the H1N1 vaccine.
