The AZD1222 COVID-19 vaccine has shown positive early results, according to AstraZeneca.
Test results from an analysis done in clinical trials in Brazil and the UK have shown that it is a reliable and effective means of preventing the virus. Those that have taken the vaccine have had no hospitalizations or severe cases as of yet. In the analysis, there were 131 total cases.
When used in one dose, the vaccine had an efficacy of 90%. When given as two doses at least a month apart, the vaccine showed an efficacy of 62%, leading to a combined efficacy of about 70%.
The next steps are for AstraZeneca to prepare to submit all necessary documentation, information and other regulatory measures to authorities around the world. The company seeks to have early approval for the vaccine, in light of the emergency situation that is COVID-19. They will seek an Emergency Use Listing from the World Health Organization (WHO) in order to fast track the approval.
