It's drugs.

Regulator on Thursday recommended conditionally approving Johnson and Johnson's shot.

The move comes as the block seeks to speed up its stuttering inoculation campaign and boost its supplies of vaccines.

The shot is the fourth to be endorsed for use in the EU after vaccines from Pfizer, Biontech, AstraZeneca, Oxford University and Moderna.

The European Medicines Agency said.

Use of the J and J vaccine is recommended for those over 18 years of age.

Its approval follows green lights in the United States, Canada and Bahrain, while South Africa is carrying out an expedited review.

An EU official had previously told Reuters that Johnson and Johnson said it was facing supply issues and that these may complicate plans to deliver 55 million doses to the block in the second quarter of the year.

The region is having difficulty taming a spike in cases driven by a more contagious variant of the virus, with countries including Italy and France imposing fresh lockdowns.
