Coronavirus vaccine may not be available until mid-2021

The World Health Organization doesn't expect to see the coronavirus vaccine until mid-2021.

And the World Health Organization has said there probably won't be a vaccine by the end of 2020. Instead, the vaccine could arrive in the middle of next year.

None of the current vaccines in trials have shown sufficient efficacy to be effective enough for widespread global spread, said WHO spokeswoman Margaret Harris.

"We really don't expect to see a large-scale vaccination until the middle of next year."

"This phase 3 should take longer because we need to know how much protection the vaccine really is and we also need to know how safe it is."

Russia approved a coronavirus vaccine less than two months after the test.

The United States has had few trials of cooking vaccines. There have been some suggestions that vaccines will be ready in October or November, just in time for the elections.

Dr. Scott Gottlieb recently told CNBC that a coronavirus vaccine was unlikely to be ready by then.

"I think it is highly unlikely. I think it is most likely that I will get a high quality result sometime in November and can make a decision on an emergency use license after that."

Experts are concerned that the United States has not planned enough to be ready to handle the vaccine, he wrote for Deseret.com.

"There is an enormous amount of work that needs to be done to prepare for this vaccination program and it will not be finished by November 1. Countries will need more financial resources than they have now," said Dr. Kelly Moore, associate director of the Program. Immunoeducation at the Immunization Action Coalition.
