[Thread] 1. What do we know about the #FDA’s decision re #JnJ ingredients made at Emergent BioSolutions?
On 11 Jun, the FDA said: 1. Two batches of #JnJ ingredients are suitable for use — but under special conditions 2. Several other batches are unsuitable for use
2. Shortly before the FDA released its statement, the NYT reported: 1. The FDA told #JnJ 60 mil doses of jabs are unsuitable for use because they contain potentially contaminated ingredients made by Emergent BioSolutions 2. 10 mil doses are suitable for use, but with a warning
3. The FDA didn’t mention the nr of doses that can’t be used. But the NYT says it’s 60 million. Is that true? We don’t know for sure until the FDA releases its report. The FDA said: 1. Several batches are not suitable for use 2. More batches are still under review
4. What do we know? Sources in SA's gov say they’ve been given similar nrs: 60 million can’t be used + 10 mil (not part of the 60 mill) have been cleared. The FDA's report will clear this up.
5. What else do we know? On 11 Jun, the day of the FDA statement, #JnJ released a statement re jabs destined for Europe:
“In alignment with the precautionary measures recommended by the European Medicines Agency, the Company will not release certain batches of its ... vaccines.”
6. Late Jun 11, @healthza released a statement and said: 1. Two million of SA’s already made #JnJ jabs at Aspen in Gqebherha can’t yet be released, as they need further assessment by @SAHPRA1 2. There's a “real possibility” that Sahpra could rule that the jabs can’t be used
7. @healthza also said in its statement: 1. 300 000 cleared/unaffected #JnJ doses will be shipped to SA “as a matter of extreme urgency” 2. The expiry date of the doses has been extended from 3 to 4.5 months (before the extension they expired on 28 June)
8. The hlth dpt told me the 300 000 doses = for school staff (480 000 = originally ordered, but they were reduced to 300 000 because of concerns that we wouldn’t be able to use the 480 000 before the original expiry date of June 28. The shelf life was only extended after that).
9. The 300 000 doses for school staff are likely to be flown to SA early next week (if #JnJ releases them in time). Sahpra has to approve the extended expiry date (from June 28 to early August), but that's not a long process.
10. #JnJ doses at Aspen: Is it only SA’s which were made with ingredients from the batches the FDA is investigating? Unlikely. Aspen also fills and finishes millions of imported JnJ jabs destined for distribution to other African countries via the AU. bit.ly/3wiyv8V
11. What other implications do the potentially unusable #JnJ batches hold for Africa? The NYT says it puts a dent in the US gov’s plans to share jabs with poorer countries, as J&J jabs = one of the 3 vaccines (Pfizer, AstraZeneca and JnJ) the Biden administration plans to share.
12. What about the almost 500 000 #JnJ doses used in our #Sisonke study? The ingredients they were made with were not produced by Emergent BioSolutions, so they're not contaminated, says one of the co lead investigators, @LindaGailBekker:
13. When will we have final answers re: 1. How many doses cannot be used? (60 mil?) 2. How many doses can be used under special conditions (10 million which are not part of the 60 mil?)
The hlth dpt seems to think Sahpra will receive a report over the weekend/early next week.

🧵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
