Failure to address a global surplus of COVID vaccines raises the risk of new variants emerging, health experts warn

The world finds itself awash in COVID-19 vaccines, but governments can’t get them into arms fast enough, as hesitancy and logistical hurdles threaten to indefinitely extend the pandemic. Advocates for widespread inoculation say participants at the second global COVID-19 summit need to come up with a plan to shift focus from producing vaccines to administering shots. They warn that failure raises the risk of new variants arising, potentially with the ability to evade vaccine immunity and spark yet another wave of infections and deaths.
