Malaria Vaccine Breakthrough Announced

 A malaria vaccine breakthrough has been announced in the journal Science. 

Twenty volunteers took part in testing the PfSPZ vaccine. Malaria is a tropical disease that is spread by mosquitoes. 

An estimated 200 million people are infected with malaria every year. As reported by CNN, nearly one million people die from malaria each year. There is no approved vaccine for the deadly disease. Malaria is a serious disease that is often fatal. 

Although it is most likely transferred by mosquitoes, it has been transmitted through blood transfusions. However, increased screening of donors has reduced the risk. As reported by the Centers for Disease Control, most cases of malaria are concentrated in Africa. More than 91 percent of malaria deaths occur in Africa. Malaria is rare in the United States. Around 1,500 cases are reported in the US every year. 

However, officials suspect most residents are infected while traveling. Between 1957 and 2011, officials recorded 63 malaria outbreaks in the US. Most cases were traced back to people who were infected elsewhere. When they were bitten by local mosquitoes, the disease was spread through the communities. 

The most common symptoms of malaria include fever, chills, and illness that mimics the flu. It is generally diagnosed through blood tests. Successful treatment depends on numerous factors. However, otherwise healthy individuals usually respond to medication.

 As reported by NBC News, PfSPZ was injected into 15 volunteers. The PfSPZ vaccine uses an immature form of the disease. Nine volunteers received four injections, the remaining six received five. The research revealed that 100 percent of the volunteers with five injections were protected from the malaria.

 Six of the nine volunteers with four injections were protected. All six volunteers who did not receive the vaccine were infected. The malaria vaccine is still in development. However, the results are very promising.
