you could say that spikes are common in everyone's vaccinated body that did not get saline solution :)
No, the vaccines create the spikes in response to a certain protein that the virus needs in order for 'contact' to become infection.... problem is the protein it targets is common
your cells grow spikes around them when dna or mRNA enclosed in lipid breaches cell membrane.
Spike is that protein that contacts receptors like ACE2 and also fuses blood platelets
