The problem is there are hundreds of different cold viruses out there, and they are constantly changing. So while you can be vaccinated against the current strain of the flu, you'd have to line up and get about 200 or more anti-cold shots.Kiss and Tell
Pushing an elevator button is more likely to make you sick than kissing your under-the-weather husband. Why? If someone sneezes into his hand before hitting the button, the virus-ridden fluid from his nose awaits you.
