As governments and pharma companies all over the world prepare to bring out boosters targeting more contagious virus variants, World Health Organisation (WHO) Chief Scientist Dr. Soumya Swaminathan has stated that nations where people have got at least one dose of the COVID-19 vaccine but are now facing shortages don't need to count on these. Swaminathan stated that heterologous prime-boost immunisation or immunisation using a combination of vaccines could be of big help for these countries instead.
WHO defines heterologous prime-boost immunisation as a form of vaccination wherein two different vectors or delivery systems expressing the same or overlapping antigenic inserts are administered.
