Has anyone heard that there is a new recommendation to get a whooping cough booster after 5 years as an adult if you're going to be around a baby? My bro and SIL are asking us to get the booster to be around their baby (even though we're only going to see him monthly or so) when we both got the vaccine when I was pregnant about 5 years and 3 months ago. The only thing I can find online is 10 years, if anything. We're going to do it, of course, since it couldn't hurt. I just wasnt in a rush about it.
