What exactly does it mean when you hear the COVID-19 vaccine is 90 or 95 percent effective? And should you get one if you have certain pre-existing conditions?

It could be too early to tell.

That's a similar sentiment from doctors, pharmacies, and medical experts alike.

With several companies announcing early results their COVID-19 vaccine is 90-percent effective it opens the doors for dozens of questions that research cannot answer today.

Dr. Dee Banks an infectious disease physician said, "THIS VACCINE is good at PREVENTing AGAINST THE DISEASE  but were not quite sure about preventing the infection."

In the real world, vaccine recipients may have pre-existing conditions, that's why researchers and the CDC will go through the data already obtained meticulously before anything is authorized.

That research will watch how long immunity lasts and analyze how well the vaccine decreases the severity of COVID-19.

The first batch of the vaccine will be going to health care workers, then those over 65 and the rest of the population probably not until spring.

In Ohio, several hospitals have already been PREPOSITIONED for vaccine distribution.

So if your doctor doesn't have an answer for you right now, patience is key.
