Neuroscience: exploring the brain By Mark F. Bear, Barry W. Connors, Michael A. Paradiso explains the following in regards to the organs of smell:
“Sniffing brings air into the convoluted nasal passages but only a small percentage of that air passes over the olfactory epithelium. The epithelium exudes a thin coating of mucus, which flows constantly and is replaced about every ten minutes. Chemical stimuli in the air, called odorants, dissolve in the mucus layer before they reach receptor cells. Mucus consists of a water base with dissolved mucuspolysaccharides (long chains of sugars); a variety of proteins, including antibodies, enzymes, and odorant binding proteins; and salts. The antibodies are critical because olfactory cells can be a direct route by which some viruses (such as the rabies virus) and bacteria enter the brain. Also important are odorant binding proteins which are small and soluble and may help concentrate odorants in the mucus.” Link:
Now, a vaccine like Flumist and Tami flu with live viruses would pose a reasonable risk of entering the brain as well as any other bacteria or virus, especially considering the amount of (weakened) virus administered in a single dose. Of course we don’t see this happening very often but the risk is there and this is one of many reasons I personally would not use this kind of vaccine, and I would not under any circumstances give it to my children.
The only one who will watch out for your own health is you. Make educated decisions.
