MACLEOD, Charles BEST and James COLLIP stands as the most in the world. Current Canadian medical research is addressing a number of key health concerns that range from vaccination to surviving cancer. Microbiologists are developing a new meningitis vaccine through innovative genetic research on mouse animal models that could improve the efficacy of vaccination. Because meningitis symptoms progress rapidly a key issue around vaccination is development of a vaccine that can stop the virus before it infects the patient. Oncologists examine the consequences of surviving cancer treatment on patients. Due to the effects of chemotherapy some people are at greater risk of developing other severe health problems such as heart disease, and tailoring survival strategies by following young cancer patients over the long term will help to improve their chances for a healthy life. Sleep researchers are investigating the connection between a sedentary lifestyle, fluid retention and the development of obstructive sleep apnea
