Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what evidence his Department used to inform the covid-19 PCR test rules for people travelling internationally without a double vaccination; and if he will publish that evidence.

We are unable to provide the specific advice and evidence as it relates to the ongoing development of Government policy. However, the Department used evidence from Public Health England to inform polymerase chain reaction testing rules. This indicated that immunisation of travellers would reduce the risk of a traveller having become infected before starting their journey and reduce the risk of transmission in groups of travellers where large proportion have been immunised.
