Interesteind guote about vaccine effectuveness in South Africa in today's AU edition of The Guardian.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Some medical experts are speaking at the National Press Club today.
Prof Robert Booy is first up. He is providing some analysis of the news that South Africa is pausing its AstraZeneca vaccinations after preliminary data showed it had a 10% effectiveness against the South African strain.
He says that economic and social issues in South Africa also effect vaccine effectiveness.
“We have had reports in the last week of Johnson & Johnson, of Novavax, having 90% protection but then in South Africa only 60% or so.
“I’d like to contend that the effect in South Africa may not just be the virus, but it might also be the population of the people because they live in such a crowded situation in many cases, apart from a few rich people...the virus can spread more easily from person-to-person.
“So a 60% effectiveness in South Africa might actually be 80% in a richer country with less crowding and a better health system.
“Now, the South African variant is worrying us. I’m not trying to down play it, I’m just trying to put it into perspective.”
