Readers came out in force to share their thoughts on Prime Minister Boris Johnson's announcement on Sunday, urging everyone over the age of 18 to get their Covid-19 booster jabs.

The target of giving every adult in England the booster jab has been brought forward by a month amid fears of a “tidal wave of Omicron” that could cause “very many deaths”.

In a pre-recorded address to the nation at 8pm on Sunday December 12, Mr Johnson scientists had discovered that being fully vaccinated is “simply not enough” to prevent the spread of the Covid-19 mutation and that, without a lightning speed mass booster campaign, the NHS could be overwhelmed.

The mission to administer millions of jabs by December 31 will see 42 military planning teams deployed across every health region, extra vaccine sites and mobile units, extended clinic opening hours to allow people to be jabbed around the clock and at weekends, and the training of thousands more volunteer vaccinators.

The announcement comes as the UK Covid alert level was raised to Level 4, up from Level 3, following a rapid increase in the number of Omicron cases being recorded.

Here's what you, the readers, had to say about the news.

Leigh-kate Waller said: "Then another variant will rear it's head and we will all need a 4th vaccine."

Poppy Taylor said: "How much longer can we keep going through the same old procedure, how many more boosters can our bodies withstand[?] Every time I visit a shop even though vaccinated I worry 'what if' - we seem no further on than when Covid first landed on our doorsteps."

Guy Brennan was concerned about the impact that the announcement might have on the current vaccination programme.

He said: "Watch what happens when everybody turns up for their booster tomorrow, because Boris said so, it will cause chaos, and overwhelm the vaccinators who are doing a great job under unprecedented circumstances."

Every adult over 18 in England who has had a second dose of a vaccine at least three months ago will be able to have their booster, the Prime Minister added.
