According to Pauchi, who serves as director of the National Institute of Allergy and Infectious Diseases, scientists hope to develop a vaccine that is 75% effective, although 50% or 60% efficacy would also be acceptable. Pauchi made the remarks at a panel at Brown University.
“The chance of 98% efficacy is not great, meaning the public health approach must not be abandoned,” he explained, “the vaccine should be thought of as a tool that will allow us to make the epidemic no longer defined as an epidemic, but rather a disease under control.”
Already last month, the US Food and Drug Administration (FDA) announced that it intends to approve the use of a corona vaccine that has been proven to be at least 50% safe and effective. Dr. Stephen Hahn, who heads the FDA, said the U.S. may eventually find itself with a vaccine that reduces the risk of corona disease by an average of only 50 percent.
Medical system executives and scientists hope that by the end of the year we will know if at least one of the many vaccines they are currently working on is safe and effective. The pharmaceutical companies Pfizer and Moderna began human trials last week and the two companies hope to recruit at least 30,000 participants for this purpose.
However, Pauchi has already expressed concern about the “resistance” of potential vaccines, noting that if the current virus behaves like other diseases in the family, the vaccine will not necessarily provide long-term protection. Still, it is estimated that there will be no complete return to routine until a vaccine is found.
Earlier this week, the World Health Organization (WHO) warned that “magic treatment” against the virus would not necessarily be found. According to the organization, the fact that three trials have already been launched does not necessarily mean that the vaccine is close to the development and use of the public. According to the organization’s secretary general, Tedros Adhanum, although there is hope that a safe and effective vaccine will be found, there is no guarantee of that. “We cannot say that there is a vaccine. It may be and it may not be, “he said.
In what he said yesterday, Fuchi noted that he maintains “cautious optimism” about the possibility that scientists will be able to develop a safe and effective vaccine. He added that the corona may never completely disappear, but world leaders can work together to reduce the virus to “low levels.”
In contrast, US President Donald Trump continues to contradict the expert’s remarks, and in his estimation the virus will “disappear” eventually. In addition, Trump estimated on Thursday that the US will have a safe and effective vaccine even before the November election.
