Abstract
The recent publication by Jessica Metcalf and others (Aug 13, p 728),1 calls for the establishment of a World Serum Bank; something we feel should be titled a World Serology Bank given its emphasis on monitoring changes in the immune response to infections. A possible rapid and cost-effective way of setting this up would be to use existing primary care sentinel networks such as the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC).2
