Other Vaccines

On 12 March 2021 the World Health Organization (WHO) listed the COVID-19 vaccine Ad26.COV2.S, developed by Janssen (Johnson & Johnson), for emergency use in all countries and for COVAX roll-out. The vaccine from Janssen is the first to be listed by WHO as a single dose regimen, which should facilitate vaccination logistics in all countries. The ample data from large clinical trials shared by the company also shows that the vaccine is effective in older populations1:
