Most elderly people in Indonesia live in intergenerational households, and isolating them from the rest of the family is often impossible.
The Ministry of Health’s spokesperson for the novel coronavirus disease vaccination program said, “Immunizing the working members of a household will mean they are not bringing the virus into the home, where their older relatives are. So, it’s one additional benefit from this approach, that by vaccinating people 18-59 years old we are also offering some protection to the elderly they live with.”
Professor Robert Read, a member of the vaccination and immunization committee that advises the UK health departments on immunization said the Indonesia approach would need a very high vaccine uptake – “at least 50% in all likelihood, to stop death and hospitalization in their older population.”
This approach relies on the vaccine preventing people from carrying the virus and passing it on to others.
