A changing shot at Ebola is a necessary step toward prevention, but the process is fraught with challenges. The first attempt at an Ebola vaccine was rejected by Guinea and was later considered premature. But scientists are trying to create a more effective vaccine that protects against all five strains of the virus. Since Ebola is related to the Marburg virus, which is lethal to humans, the vaccine can help prevent the deadly disease.
When the disease first ravaged West Africa in 2003, researchers in Winnipeg, Canada, had other pressing concerns. Severe respiratory syndrome had spread from China to Hong Kong, Singapore, and Toronto. Despite this, the group made time for their research on Ebola and had a deserved reputation. Geisbert agreed to replicate the mouse study in nonhuman primates, because nonhuman primates are the best animal model for Ebola.

The Merck vaccine has shown promise in preventing the disease and preventing it from spreading. Researchers from the pharmaceutical company Merck developed a human-grade vaccine that is effective against Ebola. However, it was never deployed in the Ebola outbreak. Merck is still waiting for FDA approval of the vaccine. It may require two doses of the vaccine to provide long-term protection. However, it could help in emergency situations such as containing the outbreak.
The new vaccine is a welcome addition to current preventive measures. However, the lack of spatial structure in these models limits their use for prevention and control. Because it is so new, it is unlikely to be used during the current outbreak in Sierra Leone. A vaccine is the only reliable way to protect the population and prevent the virus from spreading. In the meantime, the hope for a vaccine is not to late. While the virus is not yet fully eradicated, public health experts are optimistic that it will be contained.
