Frequently asked questions
Here are the most commonly asked questions that members of the public ask about vaccine research. More general questions and answers can be found on our COVID-19 page.
Is it alright to travel to take part in vaccine trials or other research in areas with high levels of COVID restrictions in place?
Yes. Please do continue to travel to take part in vaccine trials, other health research or for other healthcare requirements. Volunteers taking part in vaccine trials are even more important in areas highly affected by COVID at the moment. If you have concerns about travel to your appointment or how you will be kept safe during the appointment, please contact the research team for more information.
Please sign up to register your interest. Researchers will be looking for lots of different people to take part in their studies to make sure it works for everyone. A number of studies will be looking for healthy people with no pre-existing conditions. Some studies may be looking specifically for people of different ages with an existing condition or a suppressed immune system, as they may respond differently to a vaccine. In some studies, there will be certain people who cannot be enrolled at this time, such as people who are being treated for cancer, who are pregnant or breastfeeding, or who have certain immune conditions. However, increasingly there are studies that will be looking at people in these groups, when these can be safely trialled.
Registering with this service will allow researchers to contact you. When they do, they will discuss any pre-existing medical conditions you may have with you. You may also want to speak to your own health professional for further advice.
Will suitable volunteers who signed up first be more likely to take part than those that sign up now?
Taking part doesn't work on a first come, first served basis. Most vaccine studies will take place at multiple sites, like hospitals, across the country. Those sites may be looking for different groups of people to take part, some areas may need more people of a certain age for example.
So whether you are contacted to take part will be based on many factors including where you live and information about you and your health. Researchers will look at your answers to the questions asked when you register to see if you're suitable for their trial, and contact you if they think you may match what they need.
In the UK, the research partner of the NHS is the National Institute of Health Research (NIHR). If you sign up to be contacted about vaccine studies, only researchers on studies supported by NIHR - and who have applied to use the service and been approved - will be able to contact you. You can view a list of NIHR supported COVID-19 vaccine studies above.
When researchers from an approved study contact you, the first email will be from an official nhs.net email address. In the list above, you can select an approved study to find out the official email address that you will receive an email from, if you match a vaccine study. Check this list to ensure the email you receive notifying you that you may be eligible for a study is legitimate.
If you are interested in a study you receive an official email about and decide to get in touch with the study team and/or complete the online screening as directed in the email, then the study team will be in touch with you directly.
Researchers will never ask you for money or passwords. Always be alert to the risks of clicking on links or attachments. You can learn more about how to protect yourself from scam emails on the Action Fraud website.
Check back on Be Part of Research or contact the team if you are worried that an email may not be legitimate. Contact from researchers will be from one of the following email addresses: nhs.uk; nihr.ac.uk or ac.uk.
If you enrol on a vaccine study, the research team will collect information as part of that particular study. This information is held by the research team and any information that is collected about you will be kept confidential, in the same way as your medical records.
- If your doctor or consultant is not the person who approached you about the study, it can be helpful for them to be told you are taking part in a study as they will be responsible for your day-to-day healthcare; but they can only be told with your permission.
- Once the study has finished the results are usually published, and often presented at conferences. No name or any information that can identify you will be used in this presentation or any reports about the study.
If you want to know more about how the information collected about you by a study is used, speak to the study team: they are there to support you and answer any questions.
The vaccines themselves should not pose a risk to those you live with. If a household member is shielding and you are supporting them by staying at home to limit exposure to infection, then taking part in the vaccine study would require you to leave your home more frequently.
Vaccines are tested in a number of stages to make sure they are both safe and effective. You may be invited to participate in a study that is evaluating whether the vaccine is safe to be used for other people like you.
The information you are given about any study you are invited to take part in will explain what stage the vaccine is at and how it has already been tested. You can consider this information when deciding whether to take part.
The number of people the vaccine has been tested on will depend on the stage of the study. You should be told how many people have been tested before you decide to take part in a study.
There is no need to routinely self-isolate if you are taking part in a vaccine study. After some vaccines, you may experience a fever for one or two days. If this were to happen, then you may need to self-isolate depending on the current public health policy.
Common vaccine side effects include soreness, swelling and redness at the site of the vaccination and sometimes more general symptoms like tiredness, achy muscles and fever which may last for a few days and get better by themselves. The study team will give you further information about common side effects and how to manage them, and what to do if you experience any other side effects.
You do not have to tell family, friends or employers that you are part of a vaccine study. If you are admitted to hospital for any reason, we ask you to inform the staff caring for you. Please follow the study's instructions if you experience any symptoms of COVID or any unexpected side effects.
We need volunteers for the vaccine trials, to gather evidence on which vaccines are safe and effective, before a vaccine can be deployed for the wider population. It is possible that one or more vaccines will be found effective and approved for use before the trial follow-up period has ended. The Vaccines Taskforce and other relevant organisations will ensure that the best advice is made available to all trial volunteers, and that they are not disadvantaged by having taken part in a trial. This may include trial volunteers being offered a further vaccine if they are in a group set out as a priority for the newly approved vaccine. Advice will be made available to all trial participants.
Joining a research study should not affect life or critical illness insurance cover that you already have. You don’t generally have to tell your insurer that you are taking part in a research study, or the results of any investigations found during the study.
This is because life insurance is long term and continues until either you cancel it or make a claim. It is always best to check the terms and conditions of your policy with your insurer. If you are taking out a new policy, most of the time, insurance companies will ask about your health and your medical treatment, but won't be worried about the fact you are taking part in a study. But if they ask, you need to tell them, and answer all questions as fully and accurately as you can.
No, not generally, as taking part in the COVID vaccine study does not increase your risks. But do speak to the study team if you have travel planned, as it may affect when appointments and tests are booked. When applying for travel insurance, insurers will ask questions about a person's health in order to make an accurate assessment. Customers should answer any questions in the insurance application to the best of their knowledge. The insurer will ask about any pre-existing health conditions and associated medical treatments.
Participation in a clinical trial is not something that would be expected to lead to increased premiums or insurance refusal as it does not carry increased risk above that associated with the condition under trial. So, whilst having a condition itself may attract additional costs to travel insurance, participation in the clinical trial should not result in any further costs or penalties.
Yes, if this is recommended for you. You may need to wait between one to four weeks between receiving the flu vaccine and receiving any COVID vaccine, but you can still enroll in the study and discuss timing with the research team. Do not put off your flu vaccination to take part in the COVID trial, as it will give you important protection.
Some vaccine studies will ask that you do not donate blood for the duration of the study.
Do COVID-19 vaccines contain meat products? Are COVID-19 vaccines vegetarian friendly? Are COVID-19 vaccines Halal/Kosher?
There are many COVID-19 vaccines in development at the moment. We don't have details on every ingredient yet, but many of the COVID-19 vaccines are expected to be vegetarian or vegan and as and when we start deploying vaccines in the NHS, individual details will be shared on individual vaccines.
The Pfizer BioNTech and Oxford/AstraZeneca vaccines are the first vaccines to be given to people in the UK and they do not contain any components of animal origin. They are vegetarian, halal and kosher friendly.
