Bacterial Outer Membrane Vesicles (OMVs)-Based Dual Vaccine for Influenza A H1N1 Virus and MERS-CoV 2019-05-28 .txt text/plain 6278 319 49 Herein, we generated a bacterial outer membrane vesicles (OMVs)-based vaccine presenting the antigenic stable chimeric fusion protein of the H1-type haemagglutinin (HA) of the pandemic influenza A virus (H1N1) strain from 2009 (H1N1pdm09) and the receptor binding domain (RBD) of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) (OMVs-H1/RBD). In addition, the OMVs-H1/RBD vaccinated mice showed a significant increase of neutralizing antibodies against the MERS-CoV strain HKU-NRCE-270 at week 2 and reached the highest neutralizing titer 160 (7.3 log2) at week eight compared to the control group (p < 0.001) (Figures 2c and 3a) . Based on these observations we engineered the expression of antigenically-stable and immunogenic (OMVs)-based bivalent vaccine that elicits protective antibodies (Abs) following immunization to control infections with H1N1pdm09 and MERS-CoV. In summary, the results show that the generated (OMVs-H1/RBD)-based vaccine presenting the antigenic stable chimeric fusion protein of H1-type HA of the pandemic influenza A virus (H1N1) strain and RBD of MERS-CoV induces specific neutralizing antibodies against H1N1pdm09 and MERS-CoV leading to protection of immunized mice against both viruses. ./cache/cord-338538-uea9kwge.txt ./txt/cord-338538-uea9kwge.txt
