Disease in Africa: Good and Bad news

Scientists find big chink in in malaria's armor, headlines Khaleej Times. Research into how the disease enters the blood cells has led to a possible way to block all known strains of malaria from entering them, allowing scientists a specific path for which to look in the search for a vaccine.

However, another article suggests that climate change may allow insects that carry and spread diseases such as sleeping sickness, yellow fever, and malaria to propagate with greater intensity which would cause the diseases to become more common and wide-spread.

Now the question is, would a vaccine be a positive change or merely counter balance the increase in malaria and other insect-carried diseases?
