Local B-cell immunity and durable memory following live-attenuated influenza intranasal vaccination of humans Seasonal influenza vaccines are most frequently delivered as intramuscular inactivated vaccines which elicit systemic responses against the immunodominant hemagglutinin (HA) head domain. An intranasal...

In our new study we show local B-cell immunity and durable memory following live-attenuated influenza intranasal vaccination of humans. We utilized minimally invasive swabbing of human upper airway, following seasonal intramuscular or nasal (FluMist) flu vaccinations
