Influenza A virus shedding reduction observed at 12 weeks post‐vaccination when newborn pigs are administered live‐attenuated influenza virus vaccine

Abstract

This study showed significant reduction in nasal virus shedding with regard to both frequency and duration. A 1 mL intranasal dose of Ingelvac Provenza^™ given as early as 1 day of age showed protection for at least 12 weeks later as evidenced by the reduction of shedding live, viable virus after challenge with either a heterologous H1N2 strain or a heterologous H3N2 strain.
