Vaccines are not distributed systemically through the body for this reason, systemic distribution which these PEG coated solid lipid nano particles provide. Normally vaccine administration is done in a localized area like a muscle in order to prevent systemic distribution. Local immune response is adequate to create antibodies which are later distributed systemically. To distribute any kind of vaccine systemically increases the risk of shock or systemic inflammation. The PEG SLN used in this vaccine can cross the blood brain barrier, which for a vaccine is utterly fucking insane or malicious. Only an insane or malicious person would try to trigger an immune response in CNS tissue for the purpose of vaccination. What they are injecting people with is not a vaccine. It does not fit the profile of a vaccine or make logical sense as a vaccine method.
