Advice line for health professionals

Due to a technical issue,only some calls are coming through on the system and callers are being notified they have dialled an incorrect number when the line is very busy.

Please continue to call 0845 602 6712 (during opening hours) as we work with the telecoms provider to fix the problem. NaTHNaC apologises for any inconvenience this may cause.

Telephone: +44 (0)845 602 6712 (local call rate)

The advice line is usually staffed by one Specialist Nurse Advisor

Please note: mobile charges may vary

With effect from the 23 March 2020 and until further notice, the advice line opening hours will be as follows:

  • Mondays to Thursdays 11:00 - 13:00
  • Fridays 13:00 - 15:00

Please ensure that you are familiar with the detailed information available on the country specific information and the factsheets for special risk travellers as caller questions can sometimes be answered by reading the information available on the website.

Please note: NaTHNaC does not keep a central record of all yellow fever vaccines given to individuals. We are therefore unable to re-issue yellow fever certificates or provide information on previous vaccination dates / batch numbers.

Information for health professionals calling the advice line

The advice line is for health professionals who have queries about

    • travel scenarios that involve either complex itineraries.
    • travellers with special health needs.

The advice line is usually staffed by one Specialist Nurse Advisor each session and does get very busy. However, many queries can be answered by information that is available online.

In order to make best use of the service there are several resources that health professionals can check prior to calling:

Additionally, it is anticipated that callers will already have accessed key resources such as an atlas, Immunisation against infectious disease (the Green Book) and the Guidelines for malaria prevention in travellers from the United Kingdom in an attempt to find the answer to their query.

Callers are asked to have the following information available:

  • Contact telephone number and postcode of practice/clinic/pharmacy
  • Age; date of birth of babies
  • Body weight of babies (for malaria prophylaxis related enquiries)
  • Past/current medical history (including any relevant recent blood test results)
  • Past/current medication
  • The detailed itinerary of the traveller
  • Date of departure & length of trip
  • Reason for trip & planned activities whilst travelling

We are unable to answer travel health queries from the general public and non-clinical administrative members of staff.

Advice line disclaimer

The purpose of the NaTHNaC advice line is to provide guidance to healthcare professionals advising travellers with complex travel itineraries and/or special health needs.

Whilst NaTHNaC will use its clinical knowledge and expertise to advise on the most appropriate course of action, it is reliant on the information vicariously provided by healthcare professionals and, as such, is unable to review any records or consult with the traveller themself. NaTHNaC does not (and cannot) therefore accept any responsibility for clinical decisions made with regard to the administration of vaccines and prophylactics. Such decisions must be made by healthcare professionals in accordance with the individual circumstances and clinical condition of the traveller.

For the avoidance of doubt, the healthcare professional thus remains responsible for individual risk assessments relating to travel and for any clinical decisions made regarding the administration of vaccines, other prophylactics, or for information given regarding travel health.

Traveller Enquiries

We are unable to provide individual clinical advice to members of the public. If this is required, please contact your GP, pharmacist or travel health clinic for guidance at least 4 - 6 weeks ahead of travel. However, even if time is short, an appointment is still worthwhile. For other health enquiries call 111, free from any phone, or go to
