Coronavirus vaccine: 4 infections apart from COVID-19 which still don’t have a vaccine


Human Immuno Deficiency virus (HIV), which causes AIDS (Acquired Immuno Deficiency Syndrome) is one of the deadliest virus affecting 36.9 million people globally which caused rampant infection ever since it started to spread in the 1980s. While many countries, including India, have managed to lower down the spread of the infection with a host of measures, the world is still far from seeing a vaccine being developed for the infection. The most recent studies were underway in China, where scientists conducted trials using a CRISPR technology but no developments have been made on the same.

There are also a lot of challenges with developing an effective HIV vaccine. HIV virus targets the immune system in a lot of different ways, so it’s not entirely possible to develop one with full efficacy.
