This can cause a hyperinflammatory response, a cytokine storm, and a generally dysregulation of the immune system that allows the virus to cause more damage to our lungs and other organs of our body. In addition, new cell types throughout our body are now susceptible to viral infection due to the additional viral entry pathway facilitated by the FcγRII receptor, which is expressed on many different cell types.

What this means is that you can be given a vaccine, which causes your immune system to produce an antibody to the vaccine, and then when your body is actually challenged with the real pathogen, the infection is much worse than if you had not been vaccinated.
