Repeat Influenza Vaccination Linked to Higher Risk of Infection
A recent preprint co-authored by the U.S. Centers for Disease Control and Prevention’s (CDC) U.S. Flu Vaccine Effectiveness Network Investigators found that repeat annual influenza vaccines are associated with an increased risk of influenza infection.

The preprint authors initially wondered if vaccination timing and influenza infections in prior seasons may have contributed to repeat vaccinees’ increased risk of infection.
However, they concluded that these factors “cannot fully explain the increased infection risk in repeat vaccinees compared with non-repeat vaccinees.”

Aren't they just wonderful! Her add to post is interesting. I have a son working on a pipeline in B.C. that was approved many years ago that I hadn't heard of as it never makes the news. Previously he worked on Trans Mountain which was major news daily.
