On the possible interaction between vaccines and drugs

Reduction in the hepatic cytochrome P450 system activity has been described after a vaccination in previous studies.

Moreover, it is unclear how the effects of vaccines on hepatic cytochrome P450 system activity affect patients who present risk factors such as age or genetic predisposition.  Abstract

VLA Comment:  The study was done regarding the effect of vaccination on patients taking drugs.  Apparently, associated with vaccination, the vaccination interfered in Cytochrome P450 metabolism.  Hence, after vaccination, the metabolism (detoxing the various drugs out of the body) slowed down resulting in the drug remaining in the body. The conclusion intimates that vaccination has a relationship to Cytochrome P450.
