Dengue vaccines may escalate zika outbreaks!
Researchers at York University and Xi’an Jiaotong University identified that vaccinations for dengue increase the number of people contracting zika. They have also shown that more people in a particular population that are vaccinated against dengue, the earlier and larger the Zika outbreak. The research also found that the most effective way to minimize the unintended effect of dengue vaccinations on Zika outbreaks is through an integrated strategy that includes mosquito control.
More work needs to be done to understand how to optimize dengue vaccination programs and minimize the risk of Zika outbreaks.
