A novel coronavirus (Covid-19) outbreak which originated in Wuhan, China is a global health concern. The Covid-19 infection is spreading and its incidence is increasing nationwide.
If a vaccine is developed, then there will be a limited supply, at least initially, so it will be important to prioritise.
Healthcare workers who come into contact with Covid-19 patients would top the list. The disease is most deadly in older people so they would be a priority if the vaccine was effective in this age group.
However, it might be better to vaccinate those who live with or care for the elderly instead.
