If you want to prepare your body to be as healthy as possible, injections are the worst thing to do.

Why not increase your activity level, increase your exposure to sunshine if it's low, eat more vegetables and fruits, and focus on more quality rest(9-12 are the most restful)? These things will have a lasting impact on you from recovery time to prevention of getting sick in general.

Instead everyone rushes to have a quick fix, oh yes take a pill or an injection instead of maintaining the body with the best you can.

Look at the ingredients on any vaccine and tell me that they're healthy or that it's a natural thing that should be in your body, at any point in time. Tell me with a straight face that they couldn't have figured out a less toxic way to introduce you to the viruses for inoculation.

Everyone wants to do no work and consume. If that's you, get the injection and enjoy playing roulette.
