Lest you be disappointed

Medical experts warn of excessive speed in making the Corona vaccine

There is a possibility that an ineffective vaccine could lead to dangerous and unexpected side effects.

As potential vaccines for the virus enter their final stages of testing in humans, scientists and public health officials are now cautiously calming their enthusiasm.

The US vaccine initiative, known as Operation Bypass, aims to produce 300 million doses of an effective and safe vaccine by January.

If this initiative is achieved, it will be the greatest scientific achievement in history, given that such an achievement usually takes several years, if not about a decade, to develop an effective vaccine that targets a specific disease.

According to the World Health Organization, there are six vaccines in the third stage, that is, human experimentation, and there are 150 others under development around the world.

"The third stage in the vaccine does not mean that it is ready," said Mike Ryan, Executive Director of the World Health Organization's emergency program, last week, during a hypothetical discussion with the NBC news station. "The third stage means that it is the first time that it becomes ready." Where this vaccine is ready for use in humans, to find out if it is able to protect them against a specific natural disease ».

Amid this global rush to obtain a treatment for Coronavirus disease, medical experts have become more concerned that the supervisors of the US Food and Drug Organization, could face tremendous political pressure to quickly approve a vaccine for the Corona virus, although the Commissioner of the Department, Stephane Hanna, confirmed It is publicly stated that if the vaccine is not safe, the Food and Drug Administration will not approve it.

He said in a recent interview with the Journal of the American Medical Association: "If the effectiveness of the vaccine is 50%, but it is not safe, I will not agree to it." He added, "We will be very, very careful about the issue of safety, and we will be transparent about everything."

Other health officials say that if the green light is given to a particular vaccine, and it is less effective than what was said about it, this will lead to the virus spreading more widely than before.

And there is a chance that an ineffective vaccine could lead to dangerous and unexpected side effects. And Dr. David Stitz, a professor of human genetics and director of bioinformatics at the University of Michigan, believes that even if any vaccine gets accepted, it may confer short-term immunity against the virus.

"If you hope that the vaccine will be the knight that will save the world, you may be very disappointed," Dr. Stitz wrote on Twitter.

Health officials say that if a given vaccine is given the green light, and it is less effective than what was said about it, this will lead to the spread of the virus widely.
