[Thread] 1. What % of SA adults have now been fully vaccinated + with which jab?

Fully vaccinated adults (people of 18+) = 6.1%
- 3.1% have been fully vaccinated with #JnJ (they had 1 shot)
- 3% have been fully vaccinated with #Pfizer (they had 2 shots)

(3.1% + 3% = 6.1%)
2. How are provinces doing with full vaccinations?
Limpopo (8.5%), KZN (7.5%) and the Eastern Cape (7.2%) are leading the way, proportion-wise.

But when it comes to numbers, Gauteng (549 421) and KZN (543 580) have the highest number of fully vaccinated adults.
3. How do you work out how many people have been fully vaccinated? @healthza has a dashboard: bit.ly/3y9JEJV

Total full vaccinations =
#JnJ shots (1, 242, 236, you need 1 shot) + #Pfizer 2nd shots (1, 194, 931, you need 2 shots) = 2, 437 167
4. How do you calculate the proportion of adults (people of 18+) who have been fully vaccinated?

Fully vaccinated adults = 2, 437, 167
18+ population in SA (acc to @StatsSA) = 40, 121, 520

% fully vaccinated = (2, 437, 167 ÷ 40, 121, 520) x 100 = 6,07% = 6.1% (rounded off)
5. Does the 6, 613, 704 (by the end of Jul 26) on @healthza's dashboard mean 6, 613, 704 people have been vaccinated?

No. The 6, 613, 704 refers to doses administered, not people.

By Jul 26, 1, 194, 931 doses were 2nd Pfizer doses (those people had also received 1st doses).
6. How many people had received at least 1 dose of #JnJ or #Pfizer by 26 Jul?

6, 613, 704 (total doses) - 1, 194, 931 (Pfizer 2nd doses) = 5, 418, 773

Why? The people who had received Pfizer 2nd doses have had 2 shots, so we can't double count them.
7. What % of people in SA have received 1 dose of #Pfizer?
(You need 2 doses, but already get a significant amount of protection [94%] @ hospitalisation) about 2 weeks after 1 shot (study = bit.ly/2WpGC6x)

1. Nationally: 10.4%
2. EC: 13.9%
3. WC: 13.3%
4. LP: 12.4%
8. Who can get vaccinated against #COVID19 in SA? Anyone of 18 years and older (our COVID vaccines are currently not approved for use by anyone younger than 18).

🧵1. BREAKING: The peer-reviewed results of the study of a 6-monthly jab, #lenacapavir, in which not a single of the 2134 women between 16-25 years who received the jab contracted #HIV, were released at #Aids2024.

Find the full study here:

2. Women often find it hard to adhere to daily #oralPrEP. In the Purpose 1 trial, 91.5% of women returned on time for their next #lenacapavir jab at 26 weeks and 92.8% at week 52. Image
3. Only 4 women out of 2134 (0.2%) who received #lenacapavir dropped out of the trial because of injection-site reactions. Image

[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
