The Public Health England Acute Shortages Guidance was introduced on 17 April as a result of an acute shortage of PPE. Given our improved supply, this guidance has now been withdrawn.
Should similar guidance be required in the future, it would be re-issued based on the best available scientific evidence at that time.
We continue to work across government and with regulators to investigate the efficacy and scientific validity of decontaminating and repurposing single-use respirators (FFP3s), to help with resilience in the event of potential future supply shortages. If proven safe and effective, we will work closely with NHS organisations to support preparedness in the event of a future emergency situation.
