Vast majority of Britons have NO PROTECTION against Omicron | Daily Mail Online
Millions of Britons have effectively no protection against the
Omicron Covid variant, health experts have warned as the public was urged to get their booster jabs - despite chaos on the NHS booking site meaning some can't get jabs until Christmas Eve.
The highly-transmissible mutant strain is likely to make up most cases of Covid in Britain over the next two weeks, the UK Health Security Agency (UKHSA) said in a report yesterday, and could reach one million infections by the end of this month.
It comes as leaked advice from the body, sent to health secretary Sajid Javid, called for 'stringent national measures' to be brought in by December 18.
While the government said there were no imminent plans for more restrictions when Plan B was announced this week, Michael Gove warned on Friday that the government had been shown 'very challenging information' about the speed of Omicron's spread at a Cobra meeting.
And while Covid booster jabs have been shown to be effective against Omicron, there are concerns that the millions of people who are yet to get their third inoculation could be unprotected against the virus without it.
Government scientists compared 581 cases of Omicron in Britain with 56,000 of Delta to give preliminary estimates of how well vaccines protect against a variant with mutations that help it evade the body’s immune response.
They found that the mostly elderly people who had two doses of AstraZeneca several months ago had almost no protection against Omicron infection, and two Pfizer doses offered little more than 30 per cent.
But a third dose, if using Pfizer, can take protection levels back up to 71 per cent in those who had AstraZeneca the first time around and 76 per cent for those who had Pfizer.
