Relative deficiency in immune cells can account for poorer vaccination responses in the older population

In a study examining the ageing immune system and what makes it less efficient, researchers looked at the effects of COVID-19 mRNA vaccination in older adults. They found that older adults’ weaker immune response can be attributed to their relative deficiency in a specific type of T cells. As we age, the immune system’s efficacy weakens, leading to less effective defences against new pathogens—such as the SARS-CoV-2 virus. How immunosenescence in older adults affects their immune response to COVID-19 mRNA vaccinations is poorly understood and is an active area of study. A study led by Dr Vanda Ho, a PhD
