PHILADELPHIA (KYW Newsradio) — There is a great deal of talk about a vaccine to fight COVID-19. 

National Institutes of Health officials like Dr. Francis Collins say we could have one by the end of the year. Others say it is impossible to develop a vaccine. 

So what is the truth? 

If we can get a vaccine that is at least 60% effective, like the flu vaccine in most years, we could be in far better shape, because it means that someone who gets the vaccine could still contract the virus, but the hope is that even if the vaccine is not 100% effective in preventing the virus, it will reduce the severity of symptoms. 

My sense is that we will not get a perfect vaccine to make the virus to go away all at once, but it will be a combination of wearing masks, as well as developing a vaccine and treatment, that will make the difference.
