As it happened: One in five UK adults has had both coronavirus jabs - BBC News
Just under 10.8 million people in the UK have been fully vaccinated against coronavirus, figures show.
China has today announced it has administered more than 200 million vaccine doses .

After the US, which has delivered 213 million doses, it is the country with the second highest number of vaccinations in the world.

China is aiming to vaccinate 40% of the country's population by the end of June, and has in recent days been strengthening calls for eligible recipients to get vaccinated amid concerns that at its current pace of between three and four million a day, it will not reach that target.

Media have repeatedly said the country remains at risk of a domestic outbreak - via infected people entering the country from overseas - unless vaccination is accelerated.

Outlets observe the number of new Covid-19 cases worldwide has been rising for eight consecutive weeks.

Today, however, the National Health Commission's spokesperson has commented that in China, "some people have reported that it has been difficult to make an appointment for a second dose".

On Sina Weibo, China's version of Facebook or Twitter, users are talking about how that has been their experience, with commenters saying that they've still not been notified about when they will receive a second dose , or have simply been told a second appointment is currently not available.

It is more likely this is due to staff shortages than vaccine shortages. China is one of the world's largest vaccine producers, and it says it has the capacity to provide five billion doses annually .
