Seafarer vaccination programmes against Covid-19 are making progress but there are significant bottlenecks, Intercargo says in its latest annual report.

The short supply has limited crews' access to vaccines, according to the organisation that represents owners controlling about one-­quarter of the global dry bulk fleet.

"Ensuring access to the second dose of the vaccine remains a challenge and, in many cases, there is a significant gap between the two doses for seafarers," Intercargo said.
