The World Heath Organization (WHO) announced Wednesday that they expect the number of vaccines available to prevent diseases to double over the next decade to about 40. The WHO's head of vaccine research, Dr Marie-Paule Kieny, was guardedly optimistic, saying "Experience has shown that the uptake of new vaccines is extremely slow. We urgently must find solutions to deliver these powerful and proven health tools to all people at risk."
New vaccines are being developed against a range of often deadly infectious diseases including meningitis, malaria, and cervical cancer, following recent scientific breakthroughs, however scientific, financial, technical, and regulatory issues continue to present substantial obstacles to delivering vaccines to people in need, she said.
