2022-23 Flu Shots Were Effective: CDC


Referring to new data from the US Centers for Disease Control and Prevention (CDC) the 2022-2023 flu shot reduced the risk of flu-related hospitalization by nearly three quarters among children and by nearly half among adults, CNN Health writes.

Dr. Mark Tenforde, a medical officer in the CDC’s Influenza Division reportedly told “Vaccination provided substantial protection against inpatient, emergency department and outpatient illness across all ages”. He reportedly added “flu vaccination provided important protection among adults 65 and older, and people who are immunocompromised – groups that are less likely to have an immune response to vaccination, and are more likely to develop serious flu complications”, CNN writes.

Dr. Lisa Grohskopf, a medical officer in the CDC’s Influenza Division and lead for the CDC’s Vaccine Policy Unit, told CNN “This is unfortunately more than in 2020-21, for which one was recorded, and 2021-22, for which 45 were recorded. It was too soon to know whether any of these children had underlying health conditions, but previous research from the CDC showed that most pediatric deaths were among unvaccinated children”.

A statement in the CDC reads “These data underscore that flu vaccination can offer substantial benefit against flu and its potentially serious complications. While flu activity has returned to low levels at this time, CDC continues to recommend annual vaccination as long as flu is spreading in the community.”
