[Thread] 1. How does @SAHPRA1 operate?
Helen Rees, board chair:
Governing Acts require Saphra to be: 1. Transparent, fair and objective 2. Allow Sahpra to co-operate with other regulatory authorities 3. Evaluate applications of all medical devices
2. @sahpra is an autonomous entity: 1. Sahpra reports to parliament, the health minister and the Sahpra board 2. The health min appoints Sahpra's board 3. The CEO makes operational decisions, not the board
3. Boitumelo Semete-Makokotlela, @SAHPRA1 CEO: Sahpra is internationally recognised for its stringent standards. Part of the reason why the WHO has chosen SA to host the new #mRNA tech transfer hub (for #COVID vaccines), is because of the detailed, rigorous processes of Sahpra.
4. @SAHPRA1 helped to investigate the fake vaccines which entered the country last year from China and they worked with the police to stop the falsified jabs from being distributed in SA. The occurrence of fake medicines in SA is lower than in many other countries.
5. What does the CEO do? The CEO doesn't make decisions alone. There is extensive consultation with academics and scientists. If an applicant isn't satisfied with a @sahpra decision, they can appeal. First to the CEO and then to the health minister.
6. @sahpra is part of very few African regulators who are part of an international coalition of medicines regulators such as the FDA, TGA (Australia), EMA (Europe) and NAFDAC (Nigeria) to collaborate on #COVID19 product approvals. They share data and advice.
7. @SAHPRA1 doesn't procure medicines, that's the role of the public/private healthcare system. Sahpra's job is to establish whether those products are safe + whether they do what their manufacturers say they do. Once approved, both the private + public health sectors can use it.
8. These are the steps @SAHPRA1 follows in order to establish if a product such as a #COVIDVaccine is safe and effective. Sahpra also looks at manufacturing processes after it's approved a product: if production processes are not sound post approval, they can revoke an approval.
9. @SAHPRA1 assesses whether there are impurities in products to establish if they're safe. They also look at how products are packaged.
10. @SAHPRA1 looks at Phase 3 trial data that has been submitted for a product such as a #COVIDVaccine. It reassess the raw data and the way efficacy has been calculated.
11. With regards to #COVID19, @SAHPRA1 doesn't just assess vaccines. It is currently evaluating 50+ antibody COVID tests and it has overseen the approval of PPE equipment such as specialised masks, and also ventilators and treatments such as dexamethasone.
12. @SAHPRA1 can withdraw product approvals. In the case of Section 21 (emergency use authorisation) approvals (most #COVID vaccines are approved this way), it can withdraw approvals immediately. For market authorisations, there's a longer process.
13. Normally, @sahpra takes about 20 months to approve a vaccine. For #COVID19 jabs, that process has been sped up to about 90 work days.

🧵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.
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.
3. Only 4 women out of 2134 (0.2%) who received #lenacapavir dropped out of the trial because of injection-site reactions.
[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
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.
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)
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
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.
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."
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
