All western society is focused on achieving a vaccine that can end the coronavirus pandemic. But everything is not so easy. In fact, not even at the time when it can be announced that the vaccine already exists it can be said that the pandemic is over.

The CNN collect the doctor’s statements Umair Shah |, who heads the Harris County Health Department, Texas: “With the swine flu there were many moving parts. It took many weeks not just to organize everything, but to implement and do it safely and effectively. And that was a mild pandemic. “

Therefore, Shah believes that things will be much more complicated with the coronavirus and that still there’s a long way to go until the pandemic is over.

“I am cautiously optimistic that we will have a vaccine at the end of this year,” said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. “But it won’t be like flipping a switch or turn on another. It will be gradual, “he adds.

Having a vaccine does not mean immediately having a vaccine approved, distributed and in the arms of millions of people.

In the United States, the vaccine must be licensed by the United States government, a process that typically takes months or even years. Despite the fact that the United States Government has already announced that it will speed up the procedures, the vaccine has to pass yes or yes through a committee of experts.

Even going through all the steps, vaccines will be put into risk groups first, so they will not generate the herd immunity necessary to extinguish the pandemic. That will take time, even if the vaccine is ready in January, according to experts consulted by CNN.
