Flu Effectiveness of Flu Vaccine in Older Adults could be reduced


Flu vaccines can be less effective in the elderly due to lack of antibody diversity, according to a new study. However, the findings also suggest a way forward to create flu vaccines even more effectively.

The vast majority of flu-related deaths occur in patients over the age of 65, making it the main cause of death for elderly people. This is thought to be due to changes in older patients' immune systems, but a team of researchers across the country wanted to find out exactly what was leading to the phenomenon.

The researchers decided to look more closely at cells B, the cells responsible for producing antibodies, to see how they behave differently in young patients and old patients.

According to study results published in the magazine Cell Host & Microbe, the authors found that the cells B that were secured by elderly patients were getting less conversations, making them less well-known when swapping the flu virus switched rapidly.

While young patients' B cells are penetrated so that they can absorb new evolution in the flu virus, the study authors found that elderly patients B cells were originally worse.
