How soon can China achieve herd immunity?

Some 1.2 billion COVID-19 vaccine shots have been administered in China.Compared with other countries such as the US, China’s public vaccination drive had a relatively slow start. It reached its first 100 million shots on March 27, two weeks behind the US.

The rollout expanded from people in high-risk jobs to the general population in a phased manner. Since late March, China significantly accelerated promotion of free vaccinations for its whole population.

It now takes five or six days to vaccinate 100 million people, compared with about 25 days in the early stages.

China aims to achieve herd immunity as early as the end of this year, and it is already halfway to the target of completing inoculation of 80% of its population.

In terms of speed, China’s daily vaccinations rose from less than five million doses in late March to an average of 20 million in June. It just needs to administer nine million doses a day moving forward to reach herd immunity.
