Reflecting on SA experience with Omricon thus far in Gauteng - the epicentre in SA. 1. Rate of increase per capita much quicker than any of previous three waves. Strongly suggestive of more transmissible than even delta. 2. Positivity rate 30-40% in some settings.

7. Unfortunate still delay rollout of 3rd Pfizer dose to older than 60yrs and immuncompromised. Little value doing so after the wave has already peaked probably in next 2 weeks. Likewise no 2nd dose for ALL single dose JJ recipients inexcusable with 15 million vaccines in depot.

8. Health facilities under pressure due to infections in staff, needing to go into isolation for 10’days- despite the isolation (and quarantine) recommendations being outdated and probably obsolete in context of underpinning immunity and widespread infection.

9. IF downturn in infection rate and no massive surge in hospitalisation and death in the next 2-3 weeks, may well mark turning point in pandemic, particularly since SA not boosting to prevent infection and mild illness like HIC are doing (at cost exacerbating vaccine inequity)

10. Gvt response correctly remains measured by not increasing restrictions and not panicking with increase in cases, but seem to rather focussing on COVID ( excluding coincidental Ix) hospitalisation and health facility capacity. 11. Lastly, vaccine coverage still lagging.

Hi Prof. I just wanted to know, does T-cell immunity also wane as with antibodies? Or is the T-cell response still strong for those who haven't received a booster for J&J as yet
-
That is a good question, who is being tested for anti bodies and T cells

I've seen people saying SA is 100% previously infected or vaxed, 85%, and now this 73%. Where did you get this number?
