In the wake of the H1N1 flu pandemic, every mother would like to improve her baby's immunity to keep it away from H1N1. Thus, some bovine colostrum products on the market are labeled with "preventing H1N1", claiming that "its components are similar to human colostrum and some nutritional indexes even surpass human milk, significantly enhancing newborns' immunity". This attracts parents to take out a handsome amount of money to purchase such products.
