A POSTnote describing the impact of the COVID-19 pandemic on children's mental health. This briefing summarises the latest understanding from research about the effects on children throughout the pandemic, and the factors that increase vulnerability to poor mental health. It also reviews policy approaches that seek to protect children's mental health, with particular focus on recent initiatives to address this.
- COVID-19 vaccine coverage is the proportion of people who have received at least one dose of a COVID-19 vaccine. On 1 July 2021, 85% of adults aged 18 years and over had received at least one dose and 62.8% had received two doses (England).
- Vaccine hesitancy is when an individual is uncertain or less likely to receive a vaccine despite the availability of vaccination services.
- Causal factors for hesitancy include mistrust, concerns around safety and future health risks, (mis)information, societal attitudes, beliefs, and values.
- Vaccine hesitancy is seen most in young people, ethnic minorities, women, certain religions, and those from socially deprived backgrounds.
- Regionally the lowest vaccine uptake is seen in London (62.5% have received the 1st dose and 41.2% the 2nd dose).
- Vaccine uptake rates vary across ethnic groups. For individuals aged 40 years and older the rates are: White British – 92.6%; Indian – 87.5%; Chinese – 80.3%; Bangladeshi – 78.6%; Other – 77.1%; Mixed – 75.9%; White other – 72.8%; Pakistani – 70.3%; Black African – 67.8%; Black Caribbean – 63.68%.
- Evidence shows that perceptions and attitudes towards COVID-19 vaccines can change depending upon the interventions used. These include targeted information campaigns and community engagement.
COVID-19 immunisation programme
The national COVID-19 immunisation programme began in December 2019. It was designed to balance protecting the people most vulnerable to the disease against the need to deliver a national programme quickly and practically. The approach is vaccinating groups of the population to reflect age-related risk. There are two phases:
- Phase 1: completed on 13 April 2021, this targeted at-risk individuals including those aged over 50, healthcare and social workers and the clinically vulnerable to reduce the incidence of death and severe disease (see POST rapid response changing the UK COVID-19 vaccine dosing schedule).
- Phase 2: aims to offer vaccines to the remaining adult population (divided into age cohorts) by the end of July 2021. Individuals aged 18 and above are currently being invited for vaccination. As of 14 April 2021, it was reported that 3 million people who had been offered a vaccine had not received it. PHE suggest barriers to access to be the main factor, followed by vaccine hesitancy and refusal.
Public Health England estimated that 13,200 deaths and 39,700 hospitalisations have been prevented following the launch of phase 1 and 2. In April, the Joint Committee on Vaccination and Immunisation (JCVI) published their advice for phase 2 of COVID-19 vaccinations for all adults aged over 18. To vaccinate adults as quickly as possible, the programme will continue to offer vaccines by age cohorts rather than subgroups based on other risk factors:
- all those aged 40 to 49 years
- all those aged 30 to 39 years
- all those aged 18 to 29 years
The JCVI identified the following groups to be at higher risk of morbidity and mortality from COVID-19 and advised public health services to prioritise and promote vaccination to these individuals:
- Male individuals at risk of hospitalisation aged 18-49
- Individuals from certain ethnic minority groups (see POST rapid response impact of COVID-19 on different ethnic minority groups)
- Individuals with a body mass index of 30 or more
- Those experiencing socioeconomic deprivation (see ONS data COVID-19 deaths by area and deprivation)
- Those with occupations where the risk of exposure to COVID-19 is high (see POSTnote COVID-19 and occupational risk)
In March 2021 SAGE discussed the risk of a third wave of COVID-19 infections among vulnerable groups who are not directly protected, either because they are not vaccinated or because the vaccine offers insufficient protection. Depending on regional and local-level vaccine coverage, vulnerable groups may be indirectly protected by the wider vaccine uptake in the community.
However, if there are communities with lower vaccination levels, they may be more susceptible to infection and disease. Consequently, the dose schedule was changed to accelerate 2nd doses and therefore increase two dose coverage.
What is vaccine coverage?
Vaccine coverage is a term used to describe how many people in a population have received a specific vaccine. Vaccination coverage data is important; when a larger proportion of the population is vaccinated, the more protected it is.
COVID-19 vaccines reduce the risk of infection, transmission, severe morbidity and mortality (See POST Rapid Response COVID-19 vaccines and impact on transmission). The current UK approved COVID-19 vaccinations require two doses of a COVID-19 vaccine, given on separate occasions, to afford the highest level of protection. PHE cites evidence (June 2021) that shows a single dose is between 55-70% effective against symptomatic disease.
Current data on COVID-19 vaccine coverage in England
In England, as of 1 July 2021, the Government coronavirus data dashboard showed that for adults over 18 years:
- 85% (37,618,263) had received one dose
- 62.8% (27,776,520) had received two doses
This data is updated daily on the dashboard and can be sorted according to region.
What do we know about how COVID-19 vaccine coverage varies?
NHS England collects data on COVID-19 vaccinations for people aged 18 and over. There are geographic differences in coverage.
As of 1 July 2021, the lowest coverage rates were in London where 62.5% of adults had received one dose and 41.2% had received two doses. Coverage rates increase to 79.2% and 60.6% in the North East of England, with the highest rates of coverage seen in the South Western region with 81.5% having received one dose and 61.6% receiving two doses.
The ONS reported on vaccine coverage on 15 May 2021. It found that disparities are associated with:
- Socioeconomic deprivation: vaccination coverage is lowest in the most deprived areas – 84.1% compared to 93.6% in the least deprived areas. NHS data shows that coverage is 75% for those aged 50-54 in the most deprived areas of England compared to 90% in the least deprived areas.
- Ethnicity: 92.6% of White British people aged over 40 were vaccinated compared to 63.6% of Black Caribbean, 67.8% of Black African, 70.3% of Pakistani and 72.8% of White other people in the same age group.
- Age: of individuals over 90 years old, 96.0% are vaccinated. This compares to 76.6% of those aged between 40-49 years.
- Religion: People of Muslim religion or those who identified as having an ‘Other’ religion had lower vaccination rates (71.8% and 79.9% respectively) compared to those with Christian and Jewish religion (92.1% and 91.0% respectively). Those with no religion displayed a vaccination rate of 87.3%.
- Household tenure: Homeowners had a higher rate of vaccination (92.8%) compared to private rented (77.7%) and social rented (83.6%) householders.
An Understanding Society UK study (April 2021) found that disparities were also associated with pre-pandemic mental and physical health diagnosis. Individuals who have been prioritised for COVID-19 vaccinations due to physical medical conditions were more likely to accept the vaccine.
Why is vaccine coverage lower in some groups?
There are numerous reasons why someone may have chosen not to be vaccinated or to have delayed their vaccination. These include barriers to access and attitudes towards a vaccine including vaccine hesitancy.
Barrier to access
The ONS reports on barriers to COVID-19 vaccination and other studies (including the Nuffield Council on Bioethics report on vaccine access and uptake) show that individuals’ access to vaccination are influenced by numerous factors:
- timing, availability, and location of appointments;
- accessibility of transport to and from facilities where vaccines are offered;
- childcare responsibilities, particularly for larger families;
- forgetting appointments;
- indirect costs associated with vaccination, such as transport or taking time off work;
- accessibility of information, including language barriers and the ability to access and use digital systems; and
- changing address frequently is common among some groups, including traveller communities and the homeless, resulting in inaccurate or incomplete NHS records.
Some of these barriers are common and have been documented in previous vaccination programmes as highlighted in the PHE immunisation inequalities strategy (2021).
Attitudes towards a vaccine
Attitudes to COVID-19 vaccination have changed over the course of the pandemic. Data from the ONS recorded from January 2021 to May 2021 show that COVID-19 vaccine hesitancy has decreased, and positive attitudes around vaccines increased in the first three months of the COVID-19 vaccine rollout. Research from the Ipsos MORI UK Knowledge Panel confirms an increase in vaccine confidence and shows a month-by-month increase in willingness to be vaccinated (December 2020 to March 2021). Vaccine confidence refers to the level of trust individuals have towards vaccination.
In a study by the University of Oxford in autumn 2020, 58.1% of ethnic minority participants were likely or very likely to take the vaccine, and this increased to 80.5% by February 2021 after the vaccination programme began.
Understanding Society’s UK longitudinal study investigating the predictors of COVID-19 hesitancy (see definition of longitudinal studies here) identified a number of characteristics associated with increased vaccine hesitancy: lower educational attainment; coming from an ethnic minority group; being younger; being female; and coming from a socioeconomically deprived background. These findings have been reflected in many other surveys.
The Opinions and Lifestyle ONS Survey May 2021 found that:
- 13% of adults aged 16 to 29 years reported vaccine hesitancy, the highest of all age groups, whilst 9 in 10 reported positive sentiment towards a COVID-19 vaccine;
- 21% of Black or Black British adults reported vaccine hesitancy, the highest compared with all ethnic groups;
- 8% of adults in London reported hesitancy: a higher percentage than most other regions in England;
- 12% of adults in the most deprived areas of England (based on the Index of Multiple Deprivation) reported higher vaccine hesitancy, compared with 4% of adults in the least deprived areas of England.
A paper prepared by SPI-B (Independent Scientific Pandemic Influenza Group on Behaviours) for SAGE analysed a series of data and made a recommendation to examine vaccination rates in more nuanced subgroups moving beyond broader categories like age or ethnicity to understand more clearly the factors influencing vaccine uptake and to develop better messages.
Reasons for COVID-19 vaccine hesitancy
The ONS commissioned an in-depth qualitative study carried out by IFF Research that investigated vaccine refusal and uncertainty amongst 50 individuals, between February and March 2021 in the UK. It included individuals who were parents, on a lower income, who had low education attainment, belonged to an ethnic minority or were clinically vulnerable. Research suggests that factors affecting COVID-19 hesitancy include:
- Some participants displayed a lack of trust in the Government’s reporting of COVID-19 cases and the approach to vaccine roll out. Participants expressed a lack of trust towards vaccine manufacturers on account of them being granted some legal protection against civil liability where vaccine consequences may occur.
- Mistrust is a significant concern amongst some ethnic minorities. According to the HealthWatch VacciNation report, one aspect of mistrust is related to alleged systemic oppression within UK institutions and recent events like the Windrush scandal. An article in the Lancet also reports that vaccine hesitancy among people from some minority ethnic backgrounds has been linked to a lack of trust resulting from institutional racism, discrimination and historical abuses, such as the Tuskegee syphilis study.
- A review by the Nuffield Council on Bioethics found that lack of trust was also related to suspicions about motives and interests driving vaccination programmes. They report that some groups lack trust because they view vaccination as an ‘attempted ‘quick-fix’ technical solution which fails to address deeper structural social and cultural problems that affect health and disease, such as inequalities of wealth, housing and education.’
- The Lancet article found that trust can also be affected by previous interactions with healthcare systems, for example, where people have experienced inequality of access to, and quality of, healthcare. The Oxford COVID-19 vaccine hesitancy study, found that if participants had positive healthcare experiences with ‘supportive doctor interactions and good NHS care’ they were more positive about vaccination.
Safety and risks
- Participants in the ONS/IFF study believed that the COVID-19 vaccines were developed more quickly in comparison to other vaccines and that any long-term side effects were not yet understood.
- In the UCL-Penn Global COVID study, safety concerns and side-effects were a key reason that study participants gave as the reason why they were unsure about taking the vaccine. In the Healthwatch report, participants were also concerned about the potential impact of vaccines on fertility. Similar findings were found in ONS opinions and life survey where fears of long-term effects on health, side effects and how well the vaccines work were the top three reasons on reporting negative attitudes.
- Although the national vaccine programme monitors safety (see POST Rapid response monitoring COVID-19 safety in national immunisation programmes) surveys show some individuals feel that there is a lack of transparency in safety monitoring. This is also seen in the UK household longitudinal study (2021), where the main reason for hesitancy was fear over unknown future effects.
- Some participants reported stories linking the COVID-19 vaccine rollout to conspiracy theories relating to population control. This experience is supported by evidence from surveys investigating hesitancy and attitudes to COVID-19 vaccines, which found that exposure to conspiracy theories was associated with vaccine hesitancy.
- Some participants were keen to have more and clearer information on COVID-19 vaccines, and specifically on: side effects; their contents; how they were developed; and the differences between the COVID-19 vaccines. The participants admitted they would re-think their sentiment toward the vaccines if there was accessible information available about the side effects. There was some confusion and concern about the different types of COVID-19 vaccines. Media coverage with different news stories about each vaccine made it harder for individuals to understand whether they were all safe. Similar concerns were presented in the UCL-Penn Global COVID study.
- The Nuffield Council on Bioethics’ briefing states that recent studies have found that individuals that source information from mainstream media are generally more positive towards vaccines, whereas those who rely on the internet and social media platforms, where misinformation and contradictory messages may be rapidly circulated, are less positive (See POST Rapid Response COVID-19 vaccine misinformation).
Societal attitudes, beliefs, and values
- Some participants were worried about the vaccine development processes and contents of the COVID-19 vaccines, and whether these conflicted with religious and ethical beliefs. These include beliefs around the purity of the body or animal rights. A Lancet study looking at global trends in vaccine confidence and investigating barriers to vaccine uptake found that an individual’s religious belief was the most common factor associated with vaccine uptake.
- However, the study also found that some participants who were unwilling and uncertain about getting a COVID-19 vaccine felt vaccination was unnecessary since they believed they were less likely to catch or develop serious symptoms from COVID-19. This was because they were young or felt they were taking precautionary steps like natural remedies or relying on their immune system.
Interventions and recommendations to increase vaccine coverage
The Nuffield study set out several strategies being used by different governments to address barriers and to improve access to vaccines. These strategies include education, information campaigns and policies that aim to incentivise vaccination or penalise those who do not get vaccinated (such as by restricting access to certain services).
The evidence of using simple and positive information as a technique to improve vaccine sentiment was reported in a randomised control trial studying the effects of different types of written vaccination information on COVID-19 vaccine hesitancy in the UK (OCEANS-III). This provided evidence on how providing in-depth information on a personal level increases the vaccine confidence and willingness across all participants including those from different ethnic and socioeconomic backgrounds. There is are also some research suggesting interventions which protect against online misinformation (See POST Rapid Response COVID-19 vaccine misinformation) .
The Government’s equalities office published the second quarterly report on progress to address COVID-19 health inequalities (March 2021), summarising target interventions for COVID-19 vaccinations. It also reports on government pilots of community-led, localised, asymptomatic testing at places of worship in ethnically diverse areas with the aim of removing some of the main identified barriers to engaging with Test and Trace, including trust and access. The success of community approaches to testing engagement could offer a model for improving vaccine coverage.
However, the Healthwatch report cautioned that targeted communication campaigns can be “counter-productive”. It noted that some Black and Asian individuals had felt that information aimed at them had created a “sense of blame” and in some it had raised suspicions about the motivations behind the campaign. It reported that pressure to get the vaccine “felt very oppressive for some”.
Current and prospective projects in the UK to increase vaccine uptake
In February 2021 the Government published the UK COVID-19 vaccine uptake plan. This described the four key “enablers” to improving vaccine uptake across all communities:
- Working in partnership: using a community-led approach supported by the Government, NHS England and local authorities.
- Removing barriers to access: directly working with hard-to-reach and deprived communities.
- Data and information: publicly sharing data frequently and targeting information and advice via social media, tv, radio and printed materials whilst acting against incorrect claims about the virus and anti-vaccination messages.
- Conversations and engagement: providing advice and information at every opportunity in a simple format people can understand, leveraging role modelling, peer education and champions across society and sharing these examples.
The Government is also reviewing whether COVID-status certification or “vaccine passports” could be used to enable access to settings or to reduce restrictions. The consultation closed in March 2021, the review has not yet been published. The Government also ran a consultation on potential vaccine mandates for staff working with individuals of older adult care residents, which closed in May 2021. The Government responded to the consultation on 16 June. It stated that it will be bringing forward regulations to require all Care Quality Commission-regulated service providers of nursing and personal care, in care homes in England, to allow entry to the premises only to those who can demonstrate evidence of having had a complete course of an authorised COVID-19 vaccine. Entry will also be allowed for those with evidence that they are exempt from vaccination.
Some experts have raised concerns that vaccine passports could inadvertently discriminate or exacerbate existing inequalities and vaccine hesitancy. For example, if people for whom vaccination is unacceptable, untested, inaccessible, or impossible are denied access to essential goods and services. Some experts claim that it will have ‘significant implications across a wide range of legal and ethical issues. They argue that these examples signal the need for alternatives and exemptions (see COVID-19 vaccines and virus transmission).
The Local Government Association has produced a briefing on guidance and recommendations for local authorities on increasing uptake for COVID-19 vaccinations with key guiding principles being to ‘engage to understand, engage to empower and engage to evaluate’.
In order to improve public health communications with those communities most at risk from COVID-19, the Government released £23.75 million in funding in February 2021 to local authorities under the Community Champions scheme. This funding is to enable local authorities to work with community groups to tailor public health communications and to use trusted local voices to promote healthy living, encourage vaccine uptake and counter misinformation. This seeks to complement current communication campaigns aiming to engage with all communities through champions. For example, the London Borough of Southwark introduced vaccine vans and pop-up clinics in mosques and churches to reach people in familiar local locations. This approach has now been implemented by other local authorities.
The UK Government recently announced a partnership with dating apps to improve vaccine uptake. This includes online communications and online rewards and bonuses such as extra credits to boost an individual’s profile and show an individual’s support for vaccination.
The NHS has enrolled celebrities to influence and increase COVID-19 vaccine uptake in particular groups as well as the general public. A video and signed open letter featuring high profile individuals from Black British and Asian backgrounds was released to increase engagement amongst those communities – although concerns have been raised about the effectiveness of this approach as mentioned in the Healthwatch report.
A prospective 18-month research study funded by the UK Research and Innovation’s Economic and Social Research Council has been approved and will investigate the factors limiting vaccine uptake in minority ethnic groups through interviews and focus groups with community members. This in-depth exploration aims to use a behavioural sciences framework to evaluate campaigns across the UK and ‘develop evidence-based messaging which support vaccination decision making.’

A correction was made on 06.07.2021. POST corrected a sentence in the section on reasons for vaccine hesitancy under the subsection of safety and risks. It previously read ‘Participants were also concerned about the potential impact of vaccines on fertility. Safety concerns and impacting fertility was also a reason stated in participants of the UCL-Penn Global COVID study and the Healthwatch report’ and now reads ‘In the UCL-Penn Global COVID study, safety concerns and side-effects were a key reason that study participants gave as the reason why they were unsure about taking the vaccine. In the Healthwatch report, participants were also concerned about the potential impact of vaccines on fertility.’ Under the same section, under the subheading ‘information’, in the second bullet point, a sentence was added at the end which states ‘Similar concerns were presented in the UCL-Penn Global COVID-19 study’. These changes were applied to improve the accuracy of citations regarding the data and information produced from the studies cited in the rapid response.
As the UK COVID-19 immunisation programme reaches all adults, the Government has announced an update to its policy on using a COVID-19 vaccine in children. So, how does COVID-19 affect children? What will the impact of vaccinating children be on preventing disease and minimising associated risks? And what do we know about public attitudes to using COVID-19 vaccines in children?
The impact of the COVID-19 pandemic is a significant public health concern, with a growing body of research describing the effects on the population since March 2020. This POSTnote summarises the key findings from research, highlights the groups most affected and their mental health outcomes, and the limitations of current knowledge. It also discusses policy approaches to protect mental health and how healthcare services can adapt to improve outcomes.
