Covid-19: Update

My Lords, all the major vaccine companies are already looking at tweaking their existing vaccines, or developing new ones, in response to the new variants. AstraZeneca, for instance, has been working on that for some months. It is not clear, at this stage, whether we will have to start again on the vaccine programme or simply arrange new booster shots, or whether the existing vaccines will, in fact, run the full course. It is unbelievably frustrating to be in this hiatus of short knowledge—that is where we are at the moment—but please be reassured that this Government are investing absolutely everything necessary to ensure that vaccines will be available for whatever comes down the track.
