Q&A: Israel-Gaza conflict halts vaccine rollout

According to the United Nations High Commissioner for Refugees (UNHCR), conflicts in the region have left around 17 million refugees. How could the WHO approve the vaccine when clinical trials didn’t target a significant number of people and when, according to a document published by Reuters, some WHO experts were sceptical? There have also been some trials on people above 60 years old but on a smaller number, so it is hard to measure the efficacy for this group. [...]WHO recommends that countries using the vaccine should monitor its safety and efficacy.
