Professor Susan Michie, Sage behavioural scientist, has warned people may follow the lockdown restrictions less strictly after getting vaccinated for coronavirus.
She said evidence comes from Lyme disease and influenza vaccine rollouts where those vaccinated were less likely to adhere to preventative behaviours.
She told BBC Radio 4's Today programme: "The concern is that as the vaccination programme rolls out and more people are getting vaccinated themselves and seeing other people in their community getting vaccinated, that people may drop their guard."
In national surveys from December, some 29 percent of people said that after getting vaccinated they would adhere less strictly and 11 percent said they would not follow the rules.
This warning comes on the heels of Professor Jonathan Van-Tam urging the nation to continue following the rules after their vaccination during Friday’s Downing Street press briefing.

Wreath laid in West Yorkshire for Sir Tom on behalf of the Queen
The deputy Lord Lieutenant of West Yorkshire, David Pearson, has laid a wreath in Keighley - Sir Tom's birthplace - on behalf of the Queen.
The wreath featured 200 white roses around a picture of the late record-breaking fundraiser.
Wreaths of poppies were also laid by local MP Robbie Moore and the town's mayor and mayoress, Peter Corkindale and Clare Abberton.
Sir Tom was made an honorary freeman of Keighley last summer when he said "it really is great to be back" as he watched a plaque unveiled in his honour.
The hearse carrying Captain Sir Tom Moore is now being transported to the crematorium for his funeral.

'Nothing is going to happen' unless reopening of schools is successful
Geoff Barton, general secretary of the Association of School and College Leaders (ASCL), said he did not want to get into an "arms race" over which jobs were more likely to lead to people dying.
He told BBC Breakfast on Saturday that further loosening of lockdown measures were not going to go ahead unless the first phase of reopening of schools was successful.
He added: "What we don't want to do is get into some kind of arms race as to whether my job is more likely to lead to me dying than you - that's really not what I'm saying.
"I would just go back to my point - it is a national moment on which much depends.
"You were talking earlier on about festivals, etc, happening in the summer, nothing is going to happen, including retail, unless we get this first phase correct."

Captain Tom's funeral today will be "spectacular", says daughter
Sir Tom, who raised more than £32 million for the NHS with a sponsored walk of his garden in the first lockdown, died at Bedford Hospital on February 2 after testing positive for Covid-19.
His funeral will be attended by his two daughters Hannah Ingram-Moore and Lucy Teixeira, four grandchildren and his sons-in-law.
Ms Teixeira, 52, said the service will be “quite spectacular”, adding: “There’s just going to be the eight of us under full Covid restrictions, we will honour him the best way we possibly can.”
Ben Wallace, the Defence Secretary, said: “In national emergencies ordinary people do extraordinary things and inspire us all to pull together to overcome adversity. Few will have heard of Sir Tom before this crisis but his contribution and example now lives on in us all.
"The armed forces are immensely proud to contribute to the celebration of his extraordinary life of service.”

'Capt Sir Tom Moore will today get the send off he so richly deserves'
The crowds may not be able to line the streets to bid him farewell, but Captain Sir Tom Moore will today get the send off he so richly deserves for his contribution to the work of the NHS, writes Patrick Sawer.
A Second World War-era plane will soar over Sir Tom's funeral service as soldiers from the Yorkshire Regiment carry his coffin to the crematorium.
The C-47 Dakota, part of the Battle of Britain Memorial Flight which operates from RAF Coningsby in Lincolnshire, will perform the flypast, recalling the moment last year when Sir Tom punched the air in delight as a Spitfire flew over his home to mark his 100th birthday.
A firing party, a bugler and a ceremonial guard will also form part of the service, which will only be attended by Sir Tom's immediate family in accordance with Covid restrictions.

Vaccinating teachers would have given parents confidence to send children back to school
Geoff Barton, general secretary of the Association of School and College Leaders (ASCL), said vaccinating school staff against coronavirus would have given confidence to parents and young people about the reopening of schools.
When asked on BBC Breakfast what he thought about the plans to prioritise vaccines by age rather than job, he said: "I am certainly not going to argue with an eminent scientist but I think what I would say is a week on Monday we are at a moment, a national moment - 10 million children and young people are going to start the process of going back into their schools.
"The Government today is launching a campaign to try to reassure parents that they should be sending their children back - that tells you something about the level of anxiety there is.
"So, it's understandable that what teachers will say is if you want that public confidence would it not make sense that you simply say to those people working in schools, they have been vaccinated as well.
"That, I think, would strengthen the Government's position and it would be reassuring not just for the people working in schools but for parents and also young people."

'My sister and I have been creating the funeral that my father wanted'
Sir Tom Moore's funeral will be attended by eight members of his immediate family - his two daughters Hannah Ingram-Moore and Lucy Teixeira, four grandchildren and his sons-in-law.
His daughter Lucy Teixeira, 52, said the service will be "quite spectacular", adding: "There's just going to be the eight of us under full Covid restrictions, we will honour him the best way we possibly can."
There are plans to plant trees around the world in his honour, with Ms Teixeira hoping that the Trees for Tom initiative will result in a wood in his home county of Yorkshire and the reforestation of part of India, where he served during the Second World War.
"My sister and I have been creating the funeral that my father wanted," she said.
She added that she had received many messages from well-wishers, and that it was "wonderful" to see people writing in an online book of condolence.
Sir Tom asked that My Way by Frank Sinatra be played at his funeral and that his epitaph reads "I told you I was old", in reference to comedian Spike Milligan's famous epitaph "I told you I was ill".

Government launches drive to convince parents of school Covid safety
Ministers are launching a campaign to persuade parents in England that it will be safe for their children to return to face-to-face lessons next month.
The £BackToSchool campaign will highlight extra protective measures being put in place across secondary schools and colleges ahead of pupils' return - including mass asymptomatic Covid-19 testing.
It came as the Government faced criticism from education unions for not prioritising school and college staff returning to "crowded" classrooms in the next phase of the Covid-19 vaccine rollout.
The campaign, launched ahead of schools reopening from March 8, will highlight the importance of face-to-face education for pupils' social and emotional development and academic success.
Radio and social media adverts will launch on Saturday and run until March 14.
Education Secretary Gavin Williamson said: "We know the benefits that being back in school or college brings to young people's education, development and wellbeing."
He added: "The campaign launching today has details of the extra testing capacity and the strengthened safety requirements in place.

Former chancellor urges Sunak not to end emergency packages yet
Conservative former chancellor Lord (Ken) Clarke said Rishi Sunak must not yet end the successful emergency packages to protect jobs during the coronavirus crisis but urged him to prepare for bringing the mounting debt under control.
The Tory grandee, who led the Treasury under Sir John Major, told BBC Radio 4's Today programme: "He has to keep in place things like the furlough scheme, the successful parts of the package that stopped the economy collapsing and kept alive good business, good jobs, that will revive if we can get ourselves through the end of this Covid crisis.
"That means more spending, more debt piling up.
"What he also has to do is start actually preparing for how he's going to get that debt under control, how he's going to return the burden of debt to normality, how he's going to raise taxation, and I think he's set out his intention to do that."
The peer said he would look at raising personal tax and said looking at corporation tax would be "quite sensible" as it is at "quite unnaturally low levels".

'Small impact' on cases likely when schools reopen, warns expert
Asked whether cases are likely to rise after schools reopen fully on March 8, Professor Sir Mark Walport said: "There's likely to be a small impact because we've seen it every time, actually.
"It's clear that children can transmit and we know that cases among young people go up during term time and tend to go down during holidays."
He said the Government had left five weeks between the stages of lockdown easing because it takes about three to four weeks "to see the signal of change".
Second World War-era plane in flypast for Captain Sir Tom Moore's funeral
A Second World War-era plane will soar over Captain Sir Tom Moore's funeral service in honour of the veteran and NHS charity fundraiser.
The C-47 Dakota, part of the Battle of Britain Memorial Flight which operates from RAF Coningsby in Lincolnshire, will perform the flypast.
Sir Tom's 100th birthday celebrations last year included a Spitfire flypast and he was photographed punching the air as it went past.
Soldiers from the Yorkshire Regiment will carry his coffin to the crematorium on Saturday, with a firing party, a bugler and a ceremonial guard also forming part of the service.
Defence Secretary Ben Wallace said: "In national emergencies ordinary people do extraordinary things and inspire us all to pull together to overcome adversity.
"Few will have heard of Sir Tom before this crisis but his contribution and example now lives on in us all.

Age-related rollout 'fits' for people at 'higher risk of dying'
Professor Sir Mark Walport said: "It's still the case that most of the vulnerability, including in those professions which mix with a lot of people, is still with the older members of those cohorts, and so this is a strategy that maximises the number of vaccines and does it on a basis of the most vulnerable."
He added: "An age-related rollout fits with where people get the worst disease and are at higher risk of dying."
Vaccines rollout in age order 'makes sense', says former chief scientific adviser
Professor Sir Mark Walport, former chief scientific adviser to the Government, said the move to continue the rollout of coronavirus vaccines in age order, rather than prioritising the frontline professions, "makes sense".
He told BBC Breakfast: "We are building on an incredibly successful rollout, so over 19 million people have had the jab and the choice has been made to try and reduce as much as possible people getting serious disease and potentially dying.
"We know that the vulnerability goes particularly with age. There are also younger people who have been in the priority groups who have other serious illnesses, so it makes sense.
"The rollout is going in such an efficient way by doing it through the ages. Of course, there will be many teachers, many police, who are in the 40-50 age group and indeed who will have been immunised already. So, it does make sense."
House passes $1.9 trillion pandemic relief bill, sends it to Senate
The House approved a $1.9 trillion (£1.36 trillion) pandemic relief bill early on Saturday in a win for President Joe Biden, even as top Democrats tried assuring agitated progressives that they'd revive their derailed drive to boost the minimum wage.
The new president's vision for flushing cash to individuals, businesses, states and cities battered by Covid-19 passed on a near party-line 219-212 vote. That ships the massive measure to the Senate, where Democrats seem bent on resuscitating their minimum wage push and fights could erupt over state aid and other issues.
Democrats said the still-faltering economy and the half-million American lives lost demanded quick, decisive action. GOP lawmakers, they said, were out of step with a public that polling shows largely views the bill favourably.
South Korea's Disease Control and Prevention Agency has allowed health workers to squeeze extra doses from vials of coronavirus vaccines developed by AstraZeneca and Pfizer.
The decision on Saturday came after some health workers who were administering the AstraZeneca shots reported to authorities that they still saw additional doses left in the bottles that had each been used for 10 injections.
KDCA official Jeong Gyeong-shil said skilled workers may be able to squeeze one or two extra doses from each vial if they use low dead-volume syringes designed to reduce wasted medications and vaccines.
However, she said the KDCA isn't allowing health workers from combining vaccines left in different bottles to create more doses.
The KDCA had previously authorised 10 injections for each AstraZeneca vial and six for each Pfizer vial.

Philippines extends restrictions as cases rise
Philippine President Rodrigo Duterte has extended partial coronavirus curbs in the capital until the end of March, as the country awaits the arrival of vaccines, the presidential spokesman said on Saturday.
With southeast Asia's second-highest tally of infections and deaths, the Philippines has suffered lengthy, strict lockdowns in Manila and provinces, hitting an economy that was among Asia's fastest growing before the pandemic.
Curbs will stay for another month in Manila, which accounts for 40 per cent of national economic output, the spokesman, Harry Roque, said in a statement. Also under partial curbs are Mr Duterte's southern home city of Davao, and the northern city of Baguio.
The curbs limit operations of businesses and public transport.
The decision follows a report of 2,651 new virus infections, the highest daily increase in more than four months.

Where you'll (probably) be able to go this year, and when
Finally, something has emerged from the suffocating murk of lockdown. A plan for inching back into something wonderful. Normality.
Admittedly, for now, the route out of our stasis is more cryptic, crumpled treasure map than exact military strategy. And there are enough asterisks dotted around it to create a constellation. But it is a start.
The red-letter dates are April 12, when we may be allowed to take a break in the UK, and May 17, when we may be permitted to have a holiday overseas.
Every date in the plan is conditional, weighted with the caveat “no earlier than”. Still, for the first time in a while, we have cause for optimism – and can, with a reasonable amount of hope, begin dreaming of getting away later this year.
Life across Australia inched toward pre-pandemic normal on Saturday, with New South Wales and South Australia states allowing some dancing and Victoria permitting larger crowds at sporting events.
The three states, home to nearly two-thirds of Australia's 25 million people, recorded no community transmissions on Saturday. For New South Wales, the most populous state, it was 41st straight day without a local case.
The state, in addition to allowing up to 30 people to dance at weddings, eased further restrictions on the number of visitors at home. South Australia state allowed some club dancing from Friday.
People in Victoria, which this month imposed a five-day strict lockdown after a small outbreak of the coronavirus, woke up on Saturday to rules allowing stadiums to seat 50 per cent of capacity for sporting events.

US set to approve third vaccine
A US panel on Friday recommended Johnson & Johnson's one-dose Covid-19 shot for emergency approval.
The United States is the world's hardest-hit country, and its emergency use authorisation - which is now expected shortly - of the J&J vaccine would follow those for the Pfizer and Moderna doses.
"We're going to use every conceivable way to expand manufacturing of the vaccine... and make even more rapid progress," said President Joe Biden as the country tries to finally get on top of the virus that has already claimed 510,000 US lives.
J&J stressed its vaccine was proven to work with a single shot, and could be stored long-term at standard fridge temperatures, which "offers logistical and practical advantages".
South Korea said 18,489 people received their first doses of AstraZeneca's vaccine by midnight on Friday as it launched an ambitious inoculation campaign, and will begin using Pfizer/BioNTech vaccines on Saturday.
The first to receive the shots are healthcare workers, staffers at assisted care facilities and other high-risk people, with a goal of vaccinating 32 million to 36 million people - some 60 per cent to 70 per cent of the population - by September.
The government hopes to reach herd immunity, defined as at least a 70 per cent vaccine take-up, by November, as health authorities remain on alert for signs of sporadic infections.
Brazil's capital city goes into lockdown to curb surge
The governor of Brazil's capital city, Brasilia, decreed a 24-hour lockdown for all but essential services on Friday to curb a worsening Covid-19 outbreak that has filled its intensive care wards to the brim.
The drastic step came as right-wing President Jair Bolsonaro, who has repeatedly downplayed the gravity of the pandemic that has killed 250,000 Brazilians, renewed his attacks on state governors for destroying jobs with lockdowns.
"The lockdown will start today and be total, it will be 24-hours a day," said a press aide for the federal district's Governor Ibaneis Rocha. A decree published at the end of the day said the lockdown would start right after midnight on Saturday.
Intensive care wards in Brasilia, the third-largest city in Brazil with 3 million inhabitants, are as full as they were at the peak of the pandemic last year, with more than 80 per cent of the beds occupied, the health department said.
