A factory in Wales that produces AstraZeneca's COVID-19 vaccine was partially evacuated on Wednesday after it received a suspicious package and police said a bomb disposal unit was dealing with the incident.
Operated by Wockhardt UK, the plant provides so-called fill-and-finish capacity for AstraZeneca's UK supply chain, which is the final manufacturing step of putting vaccines into vials or syringes and packaging them.
AstraZeneca has agreed to supply Britain with 100 million doses of the vaccine it developed with Oxford University.
A spokesman for Prime Minister Boris Johnson said his office was being kept up to date on developments in Wales.
