"The perfect time to get vaccinated against flu is right before cases start to take off," says Dr. Kawsar Talaat, highlighting the critical timing for flu vaccination.
Dr. Robert Jacobson notes that children under nine getting vaccinated for the first time need two doses, suggesting early vaccination makes sense before school starts.
Flu vaccines take about two weeks to maximize immune response, making the end of October an ideal time for vaccination before cases peak.
Despite immunity waning after three to four months, remaining protection is still significant, emphasizing any timely vaccination is better than none.
