Drugs manufacturer Sanofi Pasteur has recalled a number of batches of their typhoid vaccine.
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a drug alert to healthcare professionals advising them of the recall of 16 batches of Typhim Vi.
Concerns around the effectiveness of the vaccine in some syringes distributed from 7 January 2011 following filling problems in the manufacturing process led to the recall.
This means some patients who have been vaccinated with Typhim Vi may not be fully protected against the disease.
“There are no concerns over the safety of this vaccine but the recall has taken place because the vaccine may not be as effective as it should be,” said Ian Holloway, MHRA Head of Defective Medicines Report Centre.
“Anyone who has been to a typhoid region of the world and has a fever, abdominal pain and vomiting should contact a healthcare professional. They can also give them information and advice about minimising the risk of getting typhoid.”
Patients are being advised if they have received the vaccine and recently returned from abroad and are unwell to contact their doctor.
The DH is working with manufacturers to help ensure current supply problems of the vaccine are resolved “as soon as possible”.
