Only a handful of people in Tayside have been given a flu vaccine that has been recalled amid fears of side effects.
NHS Tayside said there had been no reports of adverse effects after people with a rare allergy were given the egg-free Preflucel vaccine.
The vaccine is not the type most commonly given to protect against seasonal flu.
The Scottish Government recalled 2,500 Preflucel vaccines that had been distributed, but urged people not to panic.
The recall came after a batch issued in September was reportedly causing more side effects than previous vaccines.
The Government has ordered more than one million doses of other vaccines as those at risk are urged to get their seasonal jab.
NHS Tayside flu immunisation coordinator, Dr Finn Romanes, said: ”This issue affects only egg-free vaccine and is a precautionary recall.
”It is business as usual for the vast majority of the flu programme and there is no cause for concern amongst anyone who has had their flu vaccine or is planning to get vaccinated in the coming days or weeks.
”There is a very tightly controlled distribution in Tayside of the egg-free vaccine and there have been no reports of any adverse reactions in the very small number of people who have received it.
”The egg-free vaccine is a newly-introduced product and is manufactured in a different way from all other flu vaccines. Robust safety reporting mechanisms are in place to detect any issues with all medicines.
”All affected vaccine has been removed from use and this will give responsible agencies the time required to determine if there really is a problem.
”Only those with anaphylactic egg allergy require this vaccine, and this is a rare circumstance. People with other egg allergies can be safely vaccinated with low-egg vaccines, after assessment by their doctor.
”We now await news on the availability of a replacement batch of the egg-free vaccine so that we can get on with offering what is a highly effective intervention to protect these patients against flu this winter.”
