We're going to turn, now, to what may be the worst flu season in years. It's hitting early and hard this year. And abc's dr. Richard besser is talking about what all of us can do to keep from getting it. And here in the northeast, already see a lot of the flu. Yeah. I mean, this is unusually early. Take a look at this map. The east coast in particularly, the southeast, has been really slammed by the flu. What you should see is over the course of the next new months, it's going to continue to spread. It's not too late to get vaccinated against the flu. And there's choices. Once again, adults can get the shot. But there's a choice of a nasal spray vaccine. No needle involved. If you take the vaccine, can ill get the flu? The flu vaccine is not one of our better vaccines in terms of protection. But it's the best protection we have. And we won't know until later in the season how well it protects. But the vaccine strains are the same ones that are circulating. So, that is good news. The vaccine is one step. What are things people can do to prevent it? You want to wash your hands. And use alcohol sanitizer. You want to get the shot. And if you get the flu, be nice to your colleagues and friends and stay home. You can help them stay well. Some thought that you can actually get the flu from the vaccine? I get this every year. People say, I got the shot and it gave me the flu. It can give you a sore arm. It can give you a little fever. It is not going to give you the flu. Get it if you can. Dr. Richard besser, thanks very much.
