London, December 12: Britain's health authorities said on Sunday that bookings for the COVID booster vaccines for everyone aged 30 and over in England will be open from Monday, as one of the key actions aimed at tackling the rapid spread of the Omicron variant of COVID-19 in the country.

There are around 7.5 million people aged 30 to 39, and 3.5 million of those are eligible for boosters from Monday, NHS England said. It comes as early analysis shows booster jabs being effective against the Omicron variant, the first cases of which have started being hospitalised now.

There is no reported death from the variant in the UK yet, but experts warn that it is set to take over from Delta as the dominant coronavirus variant by the end of this year. Omicron in India: Chandigarh, Andhra Pradesh Detect First Cases, 3rd Case in Karnataka; Tally Rises to 36 in the Country.

"The COVID-19 booster programme is accelerating rapidly and more than 22 million people in the UK have already received their top-up, securing vital protection ahead of Christmas,” said UK Health Secretary Sajid Javid.

"This is our national mission – the most recent data shows boosters are the essential defence against Omicron and we are doing everything in our power to get jabs into arms as quickly as possible. We are now expanding the offer to over-30s – so please come forward as quickly as possible to get boosted and help our country get ahead in this race with the variant,” he said.

The expansion of the booster programme follows updated advice from the Joint Committee on Vaccination and Immunisation (JCVI), allowing millions more people to book their third top-up dose. The booking can be made two months on from their second dose, which is a month in advance of becoming eligible to receive the jab - a gap set at three months from the second dose by the JCVI.

"Booster vaccines are the best way to protect yourself and your loved ones from this virus and new variants,” said UK Vaccines Minister Maggie Throup.

"With the emergence of the new variant and the rising case numbers, there has never been a more important time to get boosted. So when it's your turn, come forward and book in,” added Dr Emily Lawson, head of the NHS COVID-19 Vaccination Programme, who also called on people to volunteer for the National Health Service (NHS) vaccination programme to help out as a “vaccinator”.

The UK Health Security Agency (UKHSA) warned that the sheer weight of numbers of people being infected with Omicron means it will find the unvaccinated or people who have had a poor immune response to the vaccine. Nagpur Reports Its First Omicron Case; Man Who Returned from West Africa Found Positive for New COVID-19 Variant.

"It is now a race between the booster and that protection, and the Omicron variant," said UK Education Secretary Nadhim Zahawi. "We are over 20 million (booster jabs) already. We are now in a race to get all adults who are eligible for their booster jab to be boostered as quickly as possible,” he said. On Saturday, the UK recorded another 54,073 COVID-19 infections, including 633 of the Omicron variant.
