World leaders who have been vaccinated have been eager to show off the moment they received their dose.

The public displays are usually intended to show confidence in the vaccines and remove any lingering doubts from those hesitant to face the needle.

Scroll through the gallery above to see them receiving their first doses, when they had them, and which vaccine they chose.

German Chancellor Angela Merkel received her first dose of AstraZeneca's Covid-19 vaccine last week.

Her decision to use AstraZeneca was significant. Enmeshed in an internecine blood clotting furore, the Oxford jab is banned among under 60s in Germany.

Using it in her own body was the strongest possible endorsement for the under-fire vaccine the 66-year-old Ms Merkel could give.

A more nativist choice would have been the German-engineered Pfizer/BioNTech vaccine chosen by her German compatriot and EU Commission President Ursula von der Leyen.

British Prime Minister Boris Johnson went native too, using the UK-engineered AstraZeneca jab -  but not all world leaders' vaccine choices have been so politicised.

Two men conspicuous by their absence are Russian and Brazilian leaders Vladimir Putin and Jair Bolsonaro.

President Putin has received both doses of a Covid vaccine but refused to do so on camera and only revealed that it was one of three produced by Russia.

President Bolsonaro spurned his vaccine completely, giving a typically outlandish and unsubstantiated reason.

"In the Pfizer contract, it's very clear: 'We're not responsible for any side effects.' If you turn into a crocodile, that's your problem,” he said.
