[Thread] 1. From TONIGHT (Fri), 8pm, adult #COVID19 hospitalisation data in SA will be available on @HealthZA's dashboard.

Milani Wolmarans, @HealthZA, #EVDS:
The data will be categorised into 3 types of patients:
1. Fully vaccinated
2. Partially vaccinated
3. Unvaccinated
2. What's happening so far?
Of 7,826 adults in hospital because of #COVID19:
- 5,731 (73%) = unvaccinated
- 321 (4%) = partially vaccinated (this = lower than fully vaccinated as there are far fewer partially than fully vaxxed people in total)
- 1,774 (22.6%) = fully vaxxed
3. What % of adults (18+) have been fully + partially vaccinated?

1. Fully vaccinated: 40.14% (if 2020 Stats SA population estimates = used)
2. Partially vaccinated (1 shot of #Pfizer only): 7.7% (12,367,221 [1st shots] - 9,289,091 [2nd shots] = 3,078,130 [1st shot only])
4. The new dashboard page will break hospitalisations down into severity of admission, so the dashboard will indicate who, in each of the patient categories, have been admitted to:
1. A general #COVID19 ward
2. A high care COVID19 unit
3. A COVID19 intensive care unit
5. What's happening so far?
Of 661 ICU admissions:
- 396 (60%) = unvaccinated
- 37 (5.6%) = partially vaccinated (1 shot of #Pfizer)
- 228 (34.5%) = fully vaccinated
6. The dashboard will have tables that categorise hospitalisations according 2 vaccination status + sex:
1. Red = unvaccinated; orange = partially vaccinated; green = fully vaccinated
2. Left graph = women; right graph = men
3. More women than men have been admitted to hospital
7. Vaccinations will also be categorised according to vaccination status and age:

1. The (left) graph shows, as expected, by far the most hospitalisations are among people for 60+
2. In the 60+ age group, 64% (2047/3200) of hospital admissions = unvaccinated
8. There will also be visual representations of hospitalisations, broken down into vaccination status and type of admission:

The graphs show that, for serious disease (high care/ICU), we have roughly double the number of admissions among unvaccinated vs. vaccinated people

[Thread] 12 things to know about the the proportion of pregnant women infected with #HIV from SA’s latest antenatal HIV survey. The survey is conducted by the @nicd_sa.

(Analysis of our 95-95-95 goals in my next thread later in Jan).

1/12 Image
2. What is the antenatal #HIV survey?

1. It measures the % of HIV+ pregnant women between the ages of 15 + 49.
2. Only women using state pregnancy clinics take part.
3. The survey has been conducted each year between 1990-2015, then in 2017, 2019 +2022. Image
3. How many pregnant women between 15-49’s blood was tested for #HIV? 37 828 out of 40 542 collected samples.
- 37 7171 = Black African women
- 37 541 didn’t live with the dad of their child
- 35,635 of dads were 5 years+ older than moms (this makes them more likely to get HIV) Image

JUST IN [Thread]:
1.@healthza's Lesley Broomberg:
An extra #COVID19 booster jab for people of 18+ in SA will become available towards the end of JANUARY
- People of 50+ qualify for a 5th dose
- People of 18+ qualify for a 4th dose
2. Lesley Broomberg: Can you mix and match with additional boosters? Yes. You can choose whether you want a #JnJ or #Pfizer booster.
3. Lesley Broomberg:
Will teens of 12-17 qualify for boosters? Not at this stage. Why not? The #VMAC = not recommended booster doses for 12-17, based on an understanding that the protection provided by 2 #Pfizer doses = adequate, as 12-17 = @ low risk of severe #COVID19 illness

[Thread] #JoePhaahla:
- Genomic surveillance Network reported the detection of the new subvariant XBB.1.5 in SA of a sample of a patient tested on 22 Dec
- Details of the patient = not known, it was a random sample taken for testing
- XBB.1.5 = also common in US
2. XBB.1.5 = common in US
#JoePhaahla:
- 97%+ of #COVID19 cases worldwide = still #Omicron
- XBB.1.5 cases = no major change in hospitalisations or deaths
- Immunity of SAs (vax and natural immunity) = still strong, so that is why we haven't seen much change in terms of hospital admissions/deaths

🧵1. SA's @aspenpharma will be making 4 jabs (fill + finish) — pneumococcal, rotavirus, meningococcal, hexavalent — from 2023.

How will they finance this?
With a $30 million grant from @CEPIvaccines + @gatesfoundation.

Which APIs will Aspen use?
India's Serum Institute's
2. Why is it NB that an African company makes these jabs?

#Africa imports almost all its jabs. #COVID19 showed us this results in Africa being last in line to get vaccines during pandemics. The grant to Aspen is 1 of the 1st steps to change that.
3. What's the goal?

By 2040, the African Union wants #Africa to make 60% of the jabs the continent uses.

Why?
So that Africa is better equipped 2 respond 2 outbreaks (by developing the ability to make jabs + have technology in place to also make new jabs during pandemics).

🧵1. BREAKING: @SAHPRA1 has confirmed the registration of the #HIV prevention jab, #CABLA in South Africa. On Thursday, #ViiVHealthcare issued their statement. ImageImage
2. Who can use the jab? @SAHPRA1 didn't specify restrictions for use in their statement, only that it is "a highly effective option for people at substantial risk of #HIV infection." Image
3. How does the jab work? It uses an #ARV called cabotegravir that prevents #HIV from replicating and entering someone’s cells. It’s taken every two months. Read my latest story for more. bit.ly/3ER7ejq

🧵1. @SAHPRA1 says it’s “days away” from announcing a decision on the registration of the #HIV prevention jab, #CABLA. The shot virtually wipes out your chances of contracting HIV through sex + needs to be taken every 2 months. bit.ly/3ER7ejq#WAD2022
2. How does the jab work? A bit like contraception, says @LindaGailBekker. “U take contraception before sex 2 prevent pregnancy. Similarly, u take the jab before being exposed 2 #HIV 2 prevent infection.” Listen 2 Linda-Gail on @bhekisisa’s #HealthBeat. bit.ly/3FjBlS8
3. What makes #CABLA work? An antiretroviral drug called cabotegravir. Some people with #HIV use it for treatment, along with other #ARVs. The drug prevents #HIV from entering your cells. bit.ly/3ER7ejq
