We cannot even say, but some of those who died of dengue from past year may have been vaccinated with Dengvaxia. The family may just be clueless about the vaccine which turned out that only those who are already diagnosed with Dengue before can avail of it, other otherwise severe case of Dengue if someone who's vaccinated never had Dengue before. The issue tells there is corruption in this vaccine which was rushed right before the election. But what is worrying are those kids who got injected.
