Abstract:
Measles remains an important cause of childhood mortality, and global eradication of the disease is being seriously considered. Because of limitations of the current live-attenuated vaccines, new vaccines and routes of administration are being investigated. In the article under review, the authors have measured measles-specific humoral and cellular immune responses after two doses of live-attenuated measles vaccine and found limited correlation between the two. This study highlights an important issue, namely that we cannot assume humoral and cellular immune responses to go hand in hand. However, it remains to be determined if assays with peripheral blood lymphocytes can be used as a correlate of protection from disease.
Insights
Global measles eradication efforts face challenges. This study found limited correlation between humoral and cellular immune responses after measles vaccination, questioning their combined use as protection indicators.
Area of Science:
- Immunology
- Vaccinology
- Public Health
Background:
- Measles is a significant cause of childhood mortality globally.
- Live-attenuated measles vaccines have limitations, prompting research into new vaccines and administration routes.
- Understanding immune responses to vaccination is crucial for disease control and eradication.

What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...
