World-renowned virologist, virus hunter and bioinformatician, Professor Tuli de Oliveira answers all our COVID-19 related question.
Today we asked him:
- Will the third wave truly plague South Africa until October?
- What is the maximum amount of time between shots before the first one becomes ineffective?
- How is it possible that someone in a household is infected with COVID-19 but nobody else in the household tests positive or falls ill?
- If you were recently infected by COVID-19 and you are unsure of the strain or variant, do you have immunity against the Delta Variant? Can you still carry it and infect others
Have a listen as he insightfully takes us through this all of these.
