Heroes or Zeros? Discussing Ireland's Covid strategy with ISAG's prof Aoife McLysaght

For much of the pandemic, the Independent Scientific Advocacy Group (ISAG) has recommended that Ireland should aggressively suppress virus transmission as part of a zero-Covid policy. That strategy has, however, failed to find favour with either the Government or health officials. As we prepare for the next phase of reopening in May, ISAG spokesperson, professor Aoife McLysaght, talks to Hugh about what the group would do differently, why one wrong step now could quickly lead to disaster again and why ISAG's zero-Covid campaign has been worth it, even if it fails.
