Over 3.33 billion COVID-19 vaccine doses had been administered on the Chinese mainland as of April 27. The country has accelerated vaccination among the elderly aged 60 years and above as it strives to build a nationwide solid shield against the coronavirus' onslaught. Cities across China have upgraded and optimized services including free shuttle, home-visiting vaccination and on-site consultations for the elderly who want to receive the jabs but may have difficulties in mobility. 

China launched the free vaccination campaign for its vast population of 1.4 billion against COVID-19 in February 2021. The expenses of vaccine procurements as well as the inoculation outlay are largely covered by the country's medical insurance fund and the government budget. The country announced in February 2022 a breakthrough in the vaccination drive to allow a different kind of vaccine for the booster shot.
