Israel vaccinated more than a million of its citizens, about 12 percent of its population since the vaccinations efforts began on 19 December.
The nation was delivering jabs to about 150,000 people a day, giving priority to over-60s, health workers and people who are clinically vulnerable.
Israel secured supplies of the Pfizer-BioNTech vaccine following negotiations early on in the pandemic. It is contacting people with priority access to the vaccine through its health care system – by law all Israelis must register with a recognised health care provider.
Israel has safely subdivided shipments of the Pfizer vaccine, which must be stored at -70C. This means smaller batches of the vaccine can be sent out to remote communities.
Prime Minister Benjamin Netanyahu, who is campaigning for re-election, has predicted Israel could emerge from the pandemic as early as February. It is currently in its third national lockdown.
With a rate of 11.55 vaccination doses per 100 people, followed by Bahrain at 3.49 and the UK at 1.47, according to a tracking website affiliated with Oxford University.
The US fell far short of its target of vaccinating 20 million people by the end of 2020, with just 2.78 million having received a jab by 30 December.
Meanwhile, the US government’s top infectious diseases expert, Dr Anthony Fauci, has said he does not agree with UK plans to give as many people as possible a first vaccine dose, while delaying second doses.
India has meanwhile approved two vaccines for emergency use – the Oxford-AstraZeneca vaccine and the Covaxin vaccine, developed locally by Bharat Biotech and the state-run Indian Council of Medical Research.
Two further vaccines are awaiting approval. The country aims to vaccinate 300 million people by the middle of the year and has been staging drills to prepare for mass distribution.
