Man, i noticed swelling at the site right away, anything serious?
A vaccine is basically the dead virus, so your body can recognize it, when you get infected with the real deal.But to force a reaction of your body, you have to intentionally harm your body. Thats why there are additives inside the vaccine, like aluminum or some kind of acids, which cause an immune reaction.If you would just inject the dead virus on its own, nothing would happen, because there is no danger the immune system could react to.
