Batches of the coronavirus vaccine have been pictured arriving at a hospital in south London ahead of the UK-wide rollout of the treatment this week.
Staff have been unloading doses of the Pfizer/BioNTech jab from boxes at Croydon University Hospital before placing them in freezers on the site.
Vaccinations will be administered at dozens of hospital hubs from Tuesday but people over 80 have been told not to worry if they are not called up to receive the vaccine this month.
Chris Hopson, chief executive of NHS Providers, said people need to "hang fire" and be assured they have not been forgotten if they have not received a letter or a phone call about the jab.
The UK has ordered 40 million doses of the Pfizer/BioNTech jab, enough to vaccinate 20 million people, as people need to receive two doses.
There are 800,000 doses in the first tranche, meaning 400,000 people will be vaccinated initially.
