Flu shot less effective this season for some kids, CDC report suggests
Read Original Source
This season's influenza vaccines may have been less effective against emergency room visits for some kids compared to last year, a new study by the Centers for Disease Control and Prevention suggests, though effectiveness was still high against hospitalization. So far this season, the vaccine's protection against flu hospitalization was at least 63% for children and at least 41% for adults.
AI Summary
Main Idea: A CDC report suggests this season’s flu shots were less effective at preventing some kids from getting sick enough to need urgent care, but they still worked well at preventing hospitalization.
Key Points:
- The CDC found flu vaccine protection against hospitalization stayed high this season, at least 63% for children and at least 41% for adults.
- Protection against outpatient visits, including urgent care and emergency room visits, was lower for children and teens at 32%, down from 67% last year.
- The report says the weaker outpatient result may be tied to how many infections were caused by the H3N2 flu strain.
- Adult protection against outpatient flu visits was 36%, similar to last year’s estimate of 33%.
Impact on the People
Negative Impact
Some children may face more flu-related urgent care visits this season, since CDC data suggest weaker shot protection against infection.
Positive Impact
Flu shots still appear to give strong protection against hospitalization for children and adults, which can help prevent severe illness and strain on hospitals.
