OVER half a million people have received both doses of the Covid-19 vaccine in the UK.

As of Saturday, the Government confirmed a total of 537,715 people across the UK have received both does of the Covid-19 vaccine, and 15,062,189 have received the first dose.

The two vaccines that have been approved by the MHRA that are in use in the UK, have impressive efficacy rates, offering protection to those most at risk, according to the NHS.

The short-term vaccine efficacy from the first dose of the Pfizer-BioNTech vaccine is calculated at around 90% and around 70% for Oxford AstraZeneca, with high protection against severe disease.

Given the high level of protection afforded by the first dose, expert clinical modelling produced by the Joint Committee for Vaccination and Immunisation shows vaccinating a greater number of people with a single dose will prevent more deaths and hospitalisations than vaccinating a smaller number of people with two doses.
