The Prime Minister has resisted calls from health officials to implement the Plan B to manage rising infection rates this winter, which would see tighter restrictions put in place to ease pressure on the NHS.
Health Secretary Sajid Javid admitted this week cases could reach 100,000 a day, but Downing Street insisted there was capacity available in the NHS and Plan B would not be activated only if he was under “significant pressure”.
Plan B includes advising people to work from home and the mandatory use of face masks.
Mr Johnson, who said there were no plans for another lockdown, said: ‘Vaccines are our way through this winter.
“We have made phenomenal progress, but our work is not yet finished, and we know that vaccine protection can decline after six months.
“To ensure your safety, the safety of your loved ones and everyone around you, please get your reminder when you receive the call.
“We can and will beat this virus, but only if we listen to the science and take care of each other.
“This is a call to everyone, whether you are eligible for a booster, have not yet received your second dose, or your child is eligible for a dose – vaccines are safe, they save lives and they are our way out of this pandemic. “
How and when can you get your COVID booster injection?
You will be offered a booster dose at least six months after receiving your second dose.
The NHS will contact you to let you know when it is your turn to receive a booster dose. People were asked not to contact the NHS for one until then.
Most will be asked to make an appointment at a larger vaccination center, pharmacy, or local NHS service, such as a GP’s office.
Front-line health workers or social workers can make an appointment for a booster dose online. These people do not have to wait to be contacted by the NHS.
For those who work for an NHS trust or care home, they will usually receive their booster shot through their employer.

Experts criticized the booster program and the rollout of the jab to children ages 12 to 15 for being too slow.
Four million booster doses have been given, with signs of accelerating deployment, with half a million set aside for Wednesday and Thursday alone.
This has been the busiest week so far for the National Booking Service since the start of the recall campaign.
Number 10 said: “As stated in the fall and winter plan, the winter months will lead to increased transmission of viruses.
“Vaccines are our best line of defense, but data shows that the natural immunity provided by vaccines will weaken over time, especially for the elderly and those most at risk. COVID.
“Recent studies suggest that protection against death drops from 95% to 80% for AstraZeneca after six months, and from 99% to 90% for Pfizer.
“The booster program is designed to complement this declining immunity for those most at risk during the winter months. A 15% drop in efficiency could lead to many more preventable deaths and serious illnesses from COVID.
“The first results from Pfizer show that a booster dose can increase the protection of our vaccines by up to 95.6% against symptomatic infection.
“This extra protection is vital, and anyone over the age of 50 or at high risk of COVID will be invited to their booster shot six months after their second dose. “
A government science adviser on Saturday called for tighter COVID restrictions now and not later, warning that the country is « dilly-dallying in lockdown ».
Professor Stephen Reicher told Sky News vaccines are “not quite enough” on their own and “other protections” are now needed to fight the coronavirus.
His concerns were echoed by fellow government adviser Professor Peter Openshaw, who said he was “very afraid” of another “Christmas lockdown”.
Professor Openshaw, a member of the Advisory Group on New and Emerging Respiratory Virus Threats (Nervtag), said the number of cases and death rates are currently “unacceptable”.
Daily cases overcome 50,000 Thursday for the first time since July 17th. However, Saturday saw a slight decline with 44,985 infections reported compared to 49,298 on Friday.
Likewise, official figures show that 135 deaths were recorded on Saturday, up from 180 the day before.
Speaking in a personal capacity, Professor Openshaw told BBC Breakfast: “I am very concerned that we have another lockdown Christmas if we do not act soon.
“We know that with public health measures, the time to act is immediate. There is no point in delaying.
“If you delay, you will have to take even tougher action later. Immediacy of the response is absolutely vital if you are to get things under control.
“We all really, really want a wonderful family Christmas where we can all get together.
“If this is what we want, we have to put these measures in place now to reduce transmission rates so that we can actually come together and see each other at Christmas. “

Elsewhere, the World Health Organization has warned that the vaccine alone would not be able to lift the world out of the pandemic.
Spokeswoman Margaret Harris told Times Radio: “The problem is focusing on one thing, the vaccine is not going to get us out of there. We really need to take further action.
“We have to be serious about not overcrowding. We should always consider wearing masks, especially when you are indoors. ”
