LONDON: Experts are worried that it might be difficult to get the shots in those young arms as the authorisation of COVID-19 vaccines for US children aged 5 to 11 is approaching, The Guardian has reported.

Only one third of US parents showed their willingness to vaccinate their child right away once a vaccine is available for their age group, Kaiser Family Foundation has found.

Getting people of all ages jabbed is a crucial part of ending the pandemic, Dr Saad Omer, an infectious disease epidemiologist and director of the Yale Institute for Global Health, was quoted as saying.

The cumulative number of child COVID-19 cases in the United States has surpassed six million, according to a report by the American Academy of Pediatrics.
