Due to the recent outbreak of various infectious diseases worldwide, China must increase 5% of its financial investment in vaccine development and health and epidemic prevention over the next five years, otherwise, it will not be able to effectively respond to the emergence of large-scale epidemics. From the current status of medical scientific research in China, if we can increase the financial investment by 5%, China's vaccine development can reach the world's advanced level. It can be inferred from this:. ['In the next five years, China cannot effectively respond to the emergence of large-scale epidemics unless it can increase 5% of financial investment for vaccine development and health and epidemic prevention.', 'If vaccine development reaches the world advanced level in the next five years, China will not have a large-scale outbreak.', 'If there are no outbreaks of infectious diseases in countries around the world, China will not need to increase medical investment to respond to large-scale outbreaks.', "If the financial investment is increased by 5% in the next five years, it can effectively improve China's medical research level."]
