Funding opportunity

Funding opportunity: Infections and immunity new investigator

Apply for funding to:

  • research infections and immunity
  • take the next step towards becoming an independent principal investigator

You must have:

  • a postgraduate degree
  • the support of a host research organisation eligible for MRC funding

There is no limit to the funding you can apply for, but the typical full economic cost of a project is under £1 million. MRC will usually fund 80% of the full economic cost.

This funding usually lasts 3 years and covers up to 50% of your salary.

This is an ongoing scheme. Application rounds close every January, May and September.

MRC is preparing the transition of responsive mode funding opportunities to the new UKRI Funding Service.
You may need to apply to the next round of this opportunity using the new service. Check this opportunity at the time the next round opens for confirmation on how to apply.

Who can apply

This opportunity is one of a number of new investigator research grants. It is aimed at researchers in the field of infections and immunity who are capable of becoming independent principal investigators and are now ready to take the next step towards that goal.

You can apply for funding to carry out research at your current eligible research organisation or any other eligible research organisation you want to move to. You can find details of eligible types of research organisations in section 1.1 of the MRC guidance for applicants.

You must:

  • have research organisation support
  • be able to show that your skills and experience match those in the ‘transition to independence’ stage of the MRC applicant skills and experience table, such as showing evidence of career progress and clear plans to develop your own research niche
  • provide a clear rationale of why this grant will best support your long-term career goals and chosen career route
  • have at least a postgraduate degree, although most applicants have a PhD or medical degree
  • be the sole intellectual leader of the proposed project, although we will allow co-investigators when they bring expertise to the project which is outside the applicant’s field
  • focus your application within the research area of infections and immunity

You are also eligible to apply if you:

  • are employed as a postdoctoral research assistant, but this grant cannot start until your current work finishes
  • hold a lecturer appointment, a junior fellowship or another research staff position
  • hold, or have held, an early career training fellowship such as an MRC skills development fellowship
  • do not have a contract with your chosen host institution
  • are either a non-clinical or clinically active researcher

You do not need any postdoctoral experience to be eligible to apply.

You can only have 1 new investigator research grant or fellowship proposal under consideration by MRC at any one time.

Who is not eligible to apply

You are not eligible to apply if you have achieved independence, for example by receiving substantial grant income as a principal investigator.

‘Substantial grant income’ is typically defined as grants or fellowships up to 3 years long, with more than £50,000 direct science costs (excluding the principal investigator’s salary) per year. If you are unsure whether you fulfill the eligibility criteria, contact an MRC programme manager to discuss further.

You are also not eligible if you have:

If you have any doubts about your eligibility, you should contact the relevant MRC programme manager to find out whether you can apply.

If you are still unsure as to whether you are eligible to apply, read our new investigator research grants frequently asked questions for situation-specific eligibility information.

What we're looking for


We’re looking for new investigators with a proposal for research that increases understanding within the field of infections and immunity.

The infections and immunity board funds research into infectious human disease and disorders of the human immune system.

The board supports a diverse portfolio of research of relevance to the UK and globally and addresses both long-standing questions and supports the investigation of emerging higher-risk opportunities.

Research we fund includes, but is not limited to, the following areas:

  • discovery research relating to:
    • human pathogens
    • pathogenicity
    • antimicrobial resistance
    • host pathogen responses including inflammation and the development function and disorders of the immune system where this informs mechanism of disease
  • immune disease including:
    • allergy (except asthma and other organ-based disorders)
    • transplantation immunology
    • systemic immune disorders
    • auto-immune disease
    • use of in silico systems, relevant animal models and experimental studies in humans throughout the life course
  • population-level research using epidemiological, genetic and omic approaches, and computational modelling, to:
    • elucidate disease risks, aetiologies and progression
    • understand the evolution of pathogen populations and epidemic preparedness
  • research to inform novel strategies for preventing and controlling infectious and immune disease, including:
    • vector control
    • predictive modelling
    • early development research to inform future intervention strategies including vaccines

We encourage you to contact us first to discuss your application, and for advice if you believe your research may cross MRC research board or research council interests, or if you would like to apply for a short or long-duration project.

If your application fits another research board remit better, we may decide to transfer it there to be assessed.

Co-investigators can be involved, but must bring expertise to the project which is outside the applicant’s field. Your current supervisor or lab head should not be a co-investigator.

How you spend your time

We expect you will want to combine your research project with other activities. For example:

  • time spent on other research grants or clinical duties
  • teaching
  • administration duties
  • other time spent in faculty

You may spend up to 50% of your contracted working time on this project and we will cap our contribution to your salary at this level.

If you want to spend more time than this on your project, you must provide a strong scientific rationale and your host institution will need to underwrite the extra time.

The salary requested should be in line with the research organisation’s usual new investigator levels.

Project duration

New investigator research grants usually last 3 years and are not renewable. It may be possible to apply for a longer period but you will need to justify why this is necessary.

Projects help applicants in the transition to independence so will not usually be for shorter periods.

What we will fund

We will consider requests for costs such as:

  • a salary contribution, capped at 50% of your total working time
  • the salary for any hours that your co-investigators will spend working on the project
  • support for extra research or technical posts
  • consumables and equipment
  • travel costs
  • data preservation, data sharing and dissemination costs
  • estates or indirect costs

There is no set limit to the funding available, but your application must be for an amount that:

  • is appropriate to the project
  • you can justify in order to deliver the objectives of the proposed research

Your application must show 100% of the full economic cost. We will fund up to 80% of the full economic cost of your research to your institution. Find out more about full economic costing.

We will not fund

We will not consider request for costs such as:

  • research involving randomised trials of clinical treatments
  • costs for PhD studentships
  • publication costs
  • funding to use as a ‘bridge’ between projects

Team project partner  

If you are looking to include any project partners that will support your research project, by providing cash or in-kind contributions, such as:

  • staff time
  • access to equipment
  • sites or facilities
  • the provision of data
  • software or materials

We especially encourage collaboration between academic and industry researchers.

Each project partner must provide a letter of support. If your application involves industry partners, they must provide a company letter of support if the team project partner falls within the industry collaboration framework.

Find out more about subcontractors and dual roles.

Who cannot be included as a team project partner

The individual named as the contact for the project partner organisation cannot also be named as staff.

Supporting skills and talent

We encourage you to follow the principles of The Concordat to Support the Career Development of Researchers and the Technician Commitment.
