Question to the Department of Health and Social Care:

To ask Her Majesty's Government what plans they have to rollout the combined Oxford/AstraZeneca Sputnik V vaccine, and on what scale, in the event that tests show that these vaccines can be combined successfully.

The science is currently uncertain about whether using a mixed schedule of vaccines could produce an even better immune response; and when a booster dose might be needed. For this reason, we will begin a series of trials to test various combinations of vaccines and to test booster doses. These trials do not currently include the combined Oxford/AstraZeneca Sputnik V vaccine.
