There's a rather interesting entry on Science Life today about the future of vaccines. Rob Mitchum writes:
A revolution in the scientific approach to creating vaccines has begun to yield promising new strategies for controlling previously stubborn diseases, such as meningococcus and MRSA. Those advances have also made vaccines safer than ever, eliminating even the small risk inherent in the vaccines used early in the 20th century. As scientists move on to tackling diseases of adolescence, adulthood and developing countries, the ability of vaccines to change the world is only growing, said Rino Rappuoli, global head of vaccines research at Novartis Vaccines and Diagnostics.
The entry goes on to discuss how new approaches using, for example, genomics may lead to new vaccines. It's worth reading.
