I'm struggling to find the right way to disagree with this. On one hand, we do know the downsides, provided there is no immunization. We don't develop the antibodies needed to fight the disease, and we're at greater risk for an outbreak. Polio was defeated largely due to immunizations, but there's still outbreaks that are devastating because people don't get vaccinated. I'm also not sure we can vaccinate against the cold, I think it's like the flu, it mutates too quickly.
