Can certain foods help your flu jab last longer?

Sylwch, mae’n bosibl bod gwefannau ac adnoddau allanol yn ddarparu eu cynnwys yn y Saesneg yn unig.

Older people across Wales are being asked to join a study, called the IRFLUVA study, to determine whether taking a simple food supplement can improve the long term immune response to the flu vaccine.

This Cardiff University study is open to people who are:

• aged over 65
• eligible for a normal flu vaccine
• able to visit the University Hospital of Wales in Cardiff where the trial will take place.

See the full list of exclusion criteria and other patient information.

The study lasts for 37 weeks and involves four visits. Participants will receive a normal seasonal flu vaccine and will be asked to take either a dietary supplement or placebo every day at home, with follow-up blood tests to check their general health and immunity to flu.
