BARCELONA – Desperate to jumpstart Europe's sluggish vaccination program, leaders from across the continent scrambled Wednesday in the wake of an unexpected delay in the rollout of Johnson & Johnson's COVID-19 shots amid reports of very rare blood clots.
While some European Union countries opted for caution, Poland said that it would go ahead and administer the first batch of 120,000 doses that had arrived.
Others like Spain and Portugal were left without a choice: They are still waiting for their first deliveries. The Johnson & Johnson vaccine, distributed in Europe by its subsidiary Janssen, is a key part of the continent's immunization campaign.
