Fentanyl is an addictive prescription opioid that is over 80 times mora potent than morphine. The synthetic nature of fentanyl has enabled the creation of dangerous “designer drug’ analogues that escape toxicology screening, yet display comparable potency to the parent drug. Alarmingly, a large number of fatalities have been linked to overdose of fentanyl derivatives. Herein, we report an effective immunotherapy for reducing the psychoactive effects of fentanyl class drugs. A single conjugate vaccine was created that elicited high levels of antibodies with cross-reactivity for a wide panel of fentanyl analogues, Moreover, vaccinated mice gained significant protection from lethal fentanyl doses. Lastly, a surface plasmon resonance (SPR)-based technique was established enabling drug specificity profiling of antibodies derived directly from serum. Our newly developed fentanyl vaccine and analytical methods may assist in the battle against synthetic opioid abuse.

The present application relates a composite multi-epitope expression cassette, a recombinant virus composed thereof and application thereof, and in particular to a chimeric recombinant Newcastle disease virus inserted with an IBV epitope cassette and a vaccine prepared by using the virus. The expression cassette comprises: (a) T cell epitopes derived from S1 proteins of avian infectious bronchitis virus Holte strain and avian infectious bronchitis virus QX-like strain; and (b) B cell epitopes derived from S1 protein of avian infectious bronchitis virus Australian T strain. In the present application, the multi-epitope chimeric ST/B gene of avian infectious bronchitis virus is inserted into the backbone of LaSota strain, so that the LaSota strain can express S1-T/B protein. Thus, the purpose of preventing both ND and IB diseases is achieved. In addition, the T cell epitopes and B cell epitopes act synergistically to produce an earlier and more comprehensive immune response against virus.
