The United Kingdom started administering injections of Pfizer’s coronavirus vaccine to the elderly on Tuesday morning, days after the nation became the first in the world to approve the jab.

In line with the government’s plan to vaccinate members of the public and state employees in order of priority and vulnerability to coronavirus, residents of elderly care homes were the first to receive the injection on Tuesday morning. In the coming months, the NHS intends to continue vaccinating as it works through several ‘waves’ of priority, moving down the list of age bands, and those with clinical conditions and underlying health issues that make them more susceptible to disease.
