[Thread]: 1.@Tuliodna the #DeltaVariant is now spreading extremely fast in SA and has become the dominant variant, as is the case in many other countries in the world.
2. This slide shows how the #DeltaVariant (green) is spreading in SA. Look at how the green has overtaken the yellow (this represents the Beta variant) over time.
3. The #DeltaVariant is causing many, many more deaths in Indonesia and Russia (not because it causes more severe disease, necessarily, but because it's so much more transmissible and therefore causes so many more cases).
4. In SA the #DeltaVariant is currently spreading the fastest in:
1. Limpopo
2. Kwazulu-Natal
3. Mpumalanga
5. In Limpopo we've had more than 1000 #COVID19 daily cases in a 7 day rolling average in the last week of June. This is the province where the #DeltaVariant is currently spreading the fastest.
6. In Mpumalanga and the Western Cape the #DeltaVariant is also spreading rapidly. In Gauteng the concern is that the province has reached the highest number of excess deaths since the start of the #COVID19 pandemic in SA.
7. The issue with the #DeltaVariant is that it is so transmissible (likely twice as transmissible as the original form of the virus and it is also more transmissible than the Beta variant that was previously dominant in SA). But vaccines work relatively well against Delta.
8. Even after just one dose of the #Pfizer vaccine, there is considerable protection (94%) against severe disease (so hospitalisation) caused by the #DeltaVariant.
9. A study published in the journal Nature on Thursday showed that vaccines are more effective against the #DeltaVariant than variants such as the Beta variant. It's important that SA expands its vaccine options.
10. The Delta Plus variant has a very low prevalence in SA and the Lambda variant from South America (Peru) has not been detected in SA. The #DeltaVariant is the variant to be worried about.
11. There is no evidence (currently) that the Lambda variant will overtake the #DeltaVariant in the world or in SA.

[Thread] 1. @healthza's Nicholas Crisp:
1. #VaccineRollOutSA now has 2 283 public sector sites and 314 private sector sites.
3. Most public sites do outreach, particularly in rural areas.

The slide shows the nr of sites per province.
2. This slide shows how sites are distributed across districts in provinces. Not all sites are open every day, it depends on need. As the need shifts, sites open in those districts.
3. Over 3 mil people in SA have been vaccinated:
1. By the end of next week, @healthza plans to vaccinated 250 000 people per day.
2. By the end of Aug they want to vaccinate 300 000 people per day.
3. 5.6% of SA's population has been reached with at least one vaccine dose.

[Thread] 1. LATEST #VaccineRollOutSA stats (8 Jul):

* We've crossed the 4-mil mark for doses given + data is now broken down (Pfizer 1st/2nd dose, JnJ) *

1. Total doses (#JnJ, #Sisonke, #Pfizer) = 4, 017, 442
2. People = fully vaccinated (JnJ/ 2 Pfizer doses) = 1, 253, 978
2. Total doses (#JnJ, #Sisonke, #Pfizer): 4, 017, 442

How many are Pfizer doses?
* Total: 3, 141, 867
Breakdown:
* 1st dose: 2, 763, 464
* 2nd dose: 378, 403

How many are JnJ doses?
* Total: 875, 575
Breakdown:
* Sisonke: 479, 949
* Roll-out: 395, 626
3. How many people in SA have been fully vaccinated?
Total: 1, 253, 978
Breakdown:
* JnJ: 875, 575 (you only need 1 dose)
* Pfizer: 378, 403 (these people have all had 2 Pfizer doses)

Fully vaccinated: 875, 575 (JnJ) + 378, 403 (Pfizer 2nd dose) = 1, 253, 978

[Thread] 1. GOOD NEWS about vaccine acceptance: MORE people in SA are now willing to be vaccinated. The latest results from @NIDS_CRAM show:
1. In Feb/March 71% of SAs said they'll consider being vaccinated.
2. In April/May this had increased to 76%.
2. Where does this info come from?
1. About 5000 study participants got asked to respond to the same statement in Feb/March and April/May
2. Statement = "If a vaccine for #COVID19 were available, I would get it."
2. When?
* 2 Feb to 1 March
* 6 April to 11 May
3. You can see the increase in vaccine acceptance here. Acceptance = "strong agreement" (green) + "some agreement" + "been vaccinated" (aquamarine):
1. Feb/March: 55% (green) + 16% (light green) = 71%
2. April/May: 64% (green) + 10% (light green) + 2% (aquamarine) = 76%

[Thread] 1. How many jabs does #VaccineRolloutSA have?

UPDATE: We received 190 710 #Pfizer doses on Wed night (arrival = confirmed by @healthza)

How many jabs have we now received + how many are left?

4 281 286 (without paper records)

(See nr 2 for calculations)
2. Total nr of doses #VaccineRollOutSA has received (#JnJ and #Pfizer):

7, 430, 510 (for calculations on this total, see nr 4 of this thread) + 190 710 = 7 621 220

The nr of jabs SA has left:
7 621 220 - 3 339 934 (#EVDS total used [minus Sisonke] by Wednesday) = 4 281 286
3. Are 4 281 286 doses what we have left in reality? It's likely fewer. Why? Some sites capture jabs on paper. The info = added to the EVDS later. Each day = new paper records. Until the info is entered into the EVDS, we simply don't know how many paper records there are.

[Thread]. 1. The #DeltaVariant now officially dominates in SA, according to the country's latest sequencing results:
1. Samples were collected in June
2. 48% of the genomes = Delta
3. 32% = Beta
4. Delta has been detected in all 9 provinces
(Slides = @Tuliodna and @rjlessells)
2. What are sequencing results? The coronavirus is made up of a string of genetic code. Genomic sequencing allows scientists to decode the genes of viruses and monitor how they change over time. That way they're able to figure out if there are different variants.
3. These two slides show how the May and June sequencing results compare:
1. In May, sequences were still dominated by the Beta variant (69% of samples = Beta variant; 14% of samples = #DeltaVariant)
2. In June, Delta surpassed Beta (Delta = 48%; Beta = 32%)

[Thread] 1. Nicholas Crisp (@HealthZA): How fast can we get #COVID vaccines into the community? We administered 122 701 doses in past 24 hours (that's the nr captured by the #EVDS, so not paper entries yet).
2. The numbers on @healthza's vaccine dashboard will still increase for some of the previous days because we enter backlog paper entries daily (those paper entries are added to the actual day on which the vaccinations happened). sacoronavirus.co.za/latest-vaccine…
3. 300 000 #JnJ vaccines have been administered so far in the basic education sector. Second #Pfizer vaccinations started on Monday at general sites (so for the general roll-out). In the future the government will break down the 1st and 2nd doses on @healthza's vaccine dashboard.
