Addressing a press conference in Islamabad, he said that Pakistan will receive 2.8 million doses of AstraZeneca's coronavirus vaccine on March 2 as the first batch of a donation from the worldwide COVAX programme.

State health officials say the bad weather is slowing the delivery of COVID-19 vaccines to Nebraska.

To understand these factors, the authors combined data from randomised controlled trials in the UK, Brazil, and South Africa, including 8,948, 6,753, and 1,477 people, respectively (totalling 17,178 people). By Wednesday, nearly 16 million people had received a first dose.

Some other vaccines, such as for flu, Ebola and malaria, also provide greater protection and stronger immune responses after a longer interval between doses.

The study confirmed the Anglo-Swedish drugmaker's findings from earlier this month that showed the vaccine had 76 per cent efficacy against symptomatic coronavirus infection for three months after the first dose.

Scientists are urging people to have two doses of the vaccine to increase its protection levels.

In January, the kingdom said that it would reschedule the appointments for those who registered to receive their first dose of the Pfizer-BioNTech Covid-19 vaccine, due to "the delay of the producing company in supplying the vaccine to the kingdom".

Last month, AstraZeneca agreed to supply nine million additional doses of its vaccine to the European Union following a row over the bloc's vaccination programme. For this reason, a second dose of vaccine is still recommended.

"We now have all the pieces in place for the rapid distribution of vaccines".

Professor Pollard said: "It is important to understand whether vaccines can reduce Covid-19 transmission". However, we saw a reduction in the overall number of positive cases, which indicates the vaccines may reduce infections.
