Ethics approval and consent to participate

: Human samples used for this study were unanimously obtained after informed consent in accordance with the rules set forth by the Declaration of Helsinki of the World Medical Association. For the vaccinated individual special conditions apply (see also Ethical considerations in the Materials and Methods section), since the interventions were performed as self-experimentation by an investigator and designer of the research himself on his own person. As the Declaration of Helsinki does not comment on self-experimentation the requirement for ethics approval does not apply, whereas it is widely accepted that in absence of coercion or dependency this form of interventions is an ethically and legally legitimate form of experimentation. For reference samples received from healthy blood donors Institutional Review Board approval was obtained.

: Written informed consent for publication was obtained and a consent form signed by the vaccinated individual was made available to the Editor.
