First documented vaccines began when a British doctor Edward Jenner noticed milkmaids who had cowpox never contracted small pox. He then carried out an experiment in 1796 in which puss from a cowpox blister was inserted into an eight year old boy and proved that having been inoculated with cowpox the boy was immune to smallpox. From this beginning vaccines have been developed to protect against many fatal or serious diseases. Better yet, smallpox has been eradicated thanks to the pioneering work of Edward Jenner.
Today immunization starts at birth and most are usually completed by the time the child is two years old. Why start so early? Why not wait until the child is grown? This is what the U.S. Centers for Disease Control and Prevention (CDC) has to say.

The artwork was unusual because most of them were produced using recycled materials like bottle tops, straws, beads, broken CDs, feathers, pieces of cloth, empty juice cans, and wood-logs. This was done to demonstrate the 3Rs strategy in preserving the environment. The 3Rs stand for Reduce, Reuse and Recycle. Essentially what the artists have done is to reduce waste by reusing the items mentioned and recycling them as useful things. This is a simple enough strategy that everyone can apply to help preserve our environment.
