Higher taxes on tobacco and sugar is one of the headline-grabbing keys to ending worldwide healthcare disparities by 2035, according to a report by health experts from across the globe, Business Standard reported. Investing in research, cultivating vaccines and drugs, and protecting women and children will also help developing countries achieve longer life expectancy rates and better health standards.

Officials based some of their expectations off four countries with rising health care systems known as the "four C's" for Chile, Costa Rica, China, and Cuba, according to Business Standard. The "C's" have enhanced and extended the lives of their citizens by fighting preventable diseases and ensuring the health of the two building blocks of society: women and children.

"What all the 4Cs show us is that a grand convergence between different countries, in terms of health disparities, is possible if there's a focus on preventable infections as well as the health of mothers and children," said Larry Summers, former US treasury secretary who co-chaired the report titled, "Global Health 2035: A World Converging within a Generation."

Summers believes the four C's could still benefit from increased taxation on tobacco and sugar. Taxing tobacco 50 percent in China, for example, could save 20 million people from premature deaths and create $20 billion annually in government revenue for the next 50 years, Reuters reported.

The report, compiled by Summers and 24 international health experts and economists, emphasizes prioritized spending and collaboration between countries over aid. Countries should direct their money towards combating devastating disease like HIV/Aids, malaria, tuberculosis, malaria, and tropical infections, along with the previously mentioned protection of women and children. Annual global spending for research and development in these areas must increase from $3 billion per year to $6 billion per year in order to achieve the report's desired effects, one of which is to save 10 million lives in the year 2035 alone, according to Reuters. The process, according to Summers, is "less about financial support to individual countries and more about the provision of global public goods."

"The role of international assistance, while still vital, is going to increasingly emphasise scientific research, provide templates and models that can be emulated, and focus on development of techniques and dissemination of information," Summers said in a statement.

Though Summers calls for better vaccine technology, present techniques are effective enough that the execution of his plan is more reliant on the other measures of his plan: spending money in the right areas, focusing on women and children, and countries working together.

"For the first time in human history, we are on the verge of being able to achieve a milestone for humanity: eliminating major health inequalities...so that every person on earth has an equal chance at a healthy and productive life," Summers said.
