Final answer:
The LAIV is contraindicated for children with asthma or wheezing. Specific age guidelines may vary, but in the United States, the CDC recommends not giving LAIV to children aged 2-4 years with asthma or a history of wheezing.
Step-by-step explanation:
The LAIV (Live Attenuated Influenza Vaccine) is contraindicated if a child has asthma or wheezing. This means that the vaccine should not be given to children with these conditions.
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, which can lead to wheezing and difficulty breathing. LAIV contains live, weakened forms of the influenza virus, which could potentially trigger an asthma attack or worsen symptoms in children with asthma or wheezing.
The specific age at which LAIV is contraindicated for children with asthma or wheezing can vary by country and guidelines. However, in the United States, the Centers for Disease Control and Prevention (CDC) recommends that LAIV should not be given to children aged 2 through 4 years old who have asthma or a history of wheezing.
