Earlier this week, a pharmaceutical company announced that its experimental Zika vaccine would be the first to go through human testing. The first trial will involve 40 healthy people, after which it will be tested on those with Zika and a larger number of people, reports CNN. However, it could be several years before a vaccine is ready for use, WHO told the outlet. So while this news is encouraging, there’s no reason to skip the bug spray any time soon. (Also, you probably don’t need to freak out anyway.)
