J&J manufacturing delays hit US vaccine rollout

The rollout of the US COVID-19 vaccination programme slowed up this week because manufacturing delays mean no new doses of the recently approved Johnson & Johnson vaccine are available.

The White House said on Tuesday that the government will distribute around 18.5 million doses of COVID-19 vaccines this week, fewer than last week because of a shortage of J&J’s vaccine, which was developed by its Janssen unit.
