How does the AstraZeneca vaccine compare to the other two approved COVID-19 vaccines Pfizer/BioNTech and Moderna? Dr Tony Holohan explains.
TRANSCRIPT:
The studies that have been done in relation to AstraZeneca haven't had long enough and haven't looked in the same way at the effects in older people. We fully expect that as we go on, we'll see more information that will give us further assurance in relation to the effectiveness of that vaccine. But we already know, in relation to the AstraZeneca vaccine, that we have substantial evidence, that this vaccine will work very well, it will be effective. And we're really in a really strong position that we'll be able to offer that vaccine to the population as well.
