CDC has updated select ways to operate healthcare systems effectively in response to COVID-19 vaccination. Note: For airborne viral particles, upper-room UVGI systems provide air changes per hour that are similar to the introduction of clean air into the space. While safe and effective vaccines are a great tool for prevention, it is important to continue other preventative actions such as wearing masks, performing hand hygiene, physically distancing from others, and avoiding crowded spaces and spaces with poor ventilation.7 There are several vaccine candidates, and many have been listed under WHOs emergency use.

In the context of COVID-19, the IPC goal is to support the maintenance of essential healthcare services by containing and preventing COVID-19 transmission within healthcare facilities to keep patients and healthcare workers healthy and safe. Infection prevention and control (IPC) is the practice of preventing or stopping the spread of infections from the delivery of healthcare services in facilities like hospitals, outpatient clinics, dialysis centers, long-term care facilities, or traditional practitioners. A physical distance of at least 1 meter (3 ft) between persons is recommended by the WHO to avoid infection,1 whereas CDC recommends maintaining a physical distance of at least 1.8 meters (6ft) between persons.
