Half of China's elderly population is at higher risk of severe Covid-19 because of the country's patchy vaccination campaign. China's homegrown Sinovac vaccine was found to be less effective at preventing death from Covid among the elderly than the BioNTech/Pfizer jab, unless they received three shots. Most Chinese have received either Sinovac or Sinopharm, which also requires a triple dose.

Only about half of over-80s have been fully vaccinated. Less than a fifth have received a booster shot. Some 52m people over the age of 60 have not received two jabs.
