Genetically altered vaccine approved

In 1986, the FDA licensed production of a new Hepatitis B vaccine - the first recombinant DNA (genetically altered) vaccine - by Merck & Co., marketed as RecombivaxHB. This superceded the old method of making Hepatitis B vaccines from blood taken from human chronic hepatitis B virus carriers.

I was out walking with my 4 ye...

I was out walking with my 4 year old daughter. She picked up something off the ground and started to put it in her mouth. I took the item away from her and I asked her not to do that.

"Why?" my daughter asked.

"Because it's been laying outside, you don't know where it's been, it's dirty and probably has germs" I replied.

At this point, my daughter looked at me with total admiration and asked, "Wow! How do you know all this stuff?"

"Uh," I was thinking quickly, "All moms know this stuff. It's on the Mommy Test. You have to know it, or they don't let you be a Mommy." We walked along in silence for 2 or 3 minutes, but she was evidently pondering this new information.

"OH...I get it!" she beamed, "So if you don't pass the test you have to be the daddy."

"Exactly" I replied back with a big smile on my face and joy in my heart.
