It recommends using isoflurane and sevoflurane instead of halothane as inhalation anaesthetics in all public and private hospitals nationwide
US data on hospitalisation from nine states during the period when the Delta variant was dominant also suggests that the Moderna Inc vaccine was more effective at preventing hospitalisations among individuals of all ages than vaccines from BioNTech/Pfizer Inc or Johnson & Johnson.
In that study of more than 32,000 visits to urgent care centers, emergency rooms and hospitals, Moderna's vaccine was 95 percent effective at preventing hospitalisation compared with 80 percent for Pfizer and 60 percent for J&J.
Overall, the findings, released on Friday in the US Centers for Disease Control and Prevention's weekly report on death and disease show that vaccines continue to offer strong protection from COVID-19.
