While IPV is safe for most children, certain individuals should avoid the vaccine: 1. Severe Allergies: Children with severe allergic reactions to any component of the vaccine, such as neomycin or streptomycin, should not receive IPV. 2. Previous Adverse Reactions: Those who had a severe allergic reaction to a previous IPV dose should avoid further doses. Consulting a healthcare provider is essential to determine if IPV is appropriate for a specific child.
