Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what research they have commissioned on the development of a COVID-19 vaccine which can be administered in a single dose.

The Government has invested in a portfolio of COVID-19 vaccines across a range of modalities to secure UK access to the most promising candidates.

The clinical trials of these vaccines involve testing their safety and efficacy across a range of scenarios, including testing efficacy rates of both single and multi-dose delivery methods.

This will ensure the UK has early access to those vaccines that offer the most protection against COVID-19.
