Annual influenza vaccination is a key preventive measure in childhood. In recent years, in addition to the classic injectable vaccines, a newer form of administration has been added, specifically aimed at children: the intranasal influenza vaccine.
From the autumn 2025, this specific option is also available in Greece, allowing vaccination without the use of a needle.
How it works
Unlike injectable vaccines, intranasal:
contains live attenuated viruses
acts locally in the nasopharynx
activates the immune defense from the "entrance gate" of the virus
Administered with nasal spray, in a very small amount, without pain or injury.
What ages is it aimed at?
The vaccine can be used in children from 2 to 18 years old.
Its application is given priority to children 2–5 years old, an age group for which there is also compensation.
In older children, vaccination is possible, but it is done without cost coverage.
Why would a family prefer it?
For many children, fear of injections is an obstacle to vaccination. The intranasal form:
reduces stress and resistance
facilitates the child's cooperation
quickly applied in the doctor's office
At the same time, it is a vaccine with long experience of use internationally and well-documented safety profile.
When it is not a suitable option
Due to its composition, it is not recommended for children with:
recent episodes of wheezing
known bronchial asthma
immunosuppression conditions
long-term treatment with salicylates
In these cases, protection against influenza is achieved by: injectable flu vaccines.
The available vaccination options
Today, the pediatrician can choose between:
injectable inactivated vaccines
cell culture vaccines
intranasal vaccine
The choice is made individually, based on the child's history.
When is the right time?
Influenza vaccination is recommended before the start of the seasonal outbreak, ideally from mid-October to late November.
If this is not possible, it can be done later in the winter.
How many doses are needed?
Usually enough one dose
In younger children who have not had previous full immunization, booster shots are required. two doses with a distance of 28 days
If the intranasal vaccine is not available for the second dose, it can be given with injectable vaccine.
Safety and precautions
Vaccination is postponed in case of:
febrile illness
a serious allergic reaction to a component of the vaccine
Final thoughts
The ability to get vaccinated without a shot is changing the way many children approach the process. The intranasal flu vaccine offers a modern and reliable solution, especially useful at younger ages.
The final decision is always made in collaboration with the pediatrician, who evaluates the benefits and indications for each child individually.
