Donald Trump: ''First vaccine administered. Congratulations USA! Congratulations world!''

United States President Donald Trump congratulated the world on the administration of the first dose of the COVID-19 vaccine in the country.

''First vaccine administered. Congratulations USA! Congratulations world!'' Trump tweeted.

Pfizer offers up to 95% protection against Covid-19 and was deemed safe by US regulators on Friday.

The first three million doses of the vaccine are currently being distributed to dozens of locations in all 50 states across the US.

The first shipment of those doses left a facility in Michigan on Sunday, with health workers and the elderly in line to receive the first shots as early as Monday.
