World Health Organization and partners recently released guidance on COVID-19 vaccination planning and deployment for national governments, aiming to help them design strategies for the deployment, implementation and monitoring of COVID-19 vaccines and better integrate their strategies and financing to boost efficiency.
With the vaccine race heating up as multiple companies post Phase-3 trial results, AstraZeneca's vaccine is among the top candidates globally due to its relative ease of refrigeration.
Britain gave AstraZeneca's COVID-19 vaccine a vote of confidence on Friday when it asked its regulator to assess it for a rollout after experts raised questions about trial data and the company said it might run another study to gauge the shot's efficacy.
She said vaccination in combination with tried and tested public health measures would help end the pandemic.
AstraZeneca said the administering of the half dose had been reviewed and approved by independent data safety monitors and the United Kingdom regulator, adding that the regulator publicly confirmed there was "no concern".
Pfizer and Moderna are the furthest in that process and both use a new technology, with manufacturing based in other countries.
When the vaccine becomes available to you, get it. "The newer mRNA vaccines are much more expensive when we compare it to, say, the AstraZeneca vaccine which is a more established type of vaccine platform", said Rees.

The House would go on to approve two articles of impeachment the next month and the Senate would subsequently vote to acquit him. As the weather has cooled, virus cases have surged and more than 250,000 people have died.
The government has not revealed the precise delivery timelines in their contracts with manufacturers.
Pfizer will deliver the first one million doses in the first quarter of 2021, with 1.7 million, 5.8 million and 4.3 million doses to follow in subsequent quarters.
"Big Pharma" and biotech firms have invested heavily in research and development and in boosting manufacturing during the pandemic to be able to roll out vaccine doses, Cueni told a Geneva news briefing. "We've got Manitoba, Saskatchewan, Ontario within the last 24 hours saying that they don't have details", she said. "What has the government been doing for 11 months?" The percentage could be higher for the Pfizer vaccine in Africa, where infrastructure is limited and around 60% of the population live in rural areas.
"It's important to note that the initial supply of these vaccines will be limited", he said. Yet many the world's richest nations and regions, such as the USA and the European Union, have arranged to buy hundreds of millions of vaccine doses, raising fears of delays for lower- and middle-income countries. Some of those vaccines require two doses, which means the first shipments will cover a small proportion of the Canadian population and will be given to those at the highest risk.
"The fact that we're the 10th largest economy in the world and can't produce vaccines, there's something deeply problematic about that", he said.
He said he is hopeful all Canadians could have the vaccine by late 2021 and most would be vaccinated before next September, but he cautioned it will be a challenge.
