Pfizer's COVID vaccine: Individual requires 2 shots given 3 weeks apart, says UK PM

After the formal authorisation of Pfizer-BioNTech coronavirus vaccine, United Kingdom Prime Minister Boris Johnson on December 02 said that the vials are going to be stored at -70 degrees Celsius and each person required two injections given three weeks apart.

"There are immense logistical challenges.

The vials are going to be stored at -70 degrees Celsius, each person needs two injections, three weeks apart.

So it will inevitably take some months before almost vulnerable are protected.

It's vital that we are not carried away with over-optimism or fall into the naive belief that the struggle is over.

Today, in England, we have ended national restrictions, opening up significant parts of the economy," said PM Johnson on COVID vaccine.
