[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

🧵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.

🧵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

🧵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

🧵1. @HealthZA will offer #COVID19 #Pfizer jabs 2 high-risk kids between 5 + 11 yrs on recommendation of the VMAC.

When? The #EVDS 1st needs 2 be updated, a circular needs to be issued + health workers need 2 be trained. Nicholas Crisp: "It will take at least a month." 2. What counts as a high-risk condition?
Chronic respiratory disease
Chronic heart conditions
Chronic conditions of the kidney, liver, digestive system
Endocrine disorders
Chronic neurological disease
Genetic abnormalities

[Thread] 1. SA saw its 1st confirmed #monkeypox case last week. Will there be more cases? YES. Why? The 1st case doesn’t have a travel history so he (a 30 year old man from Jhb) contracted it from someone in SA who already had it. bit.ly/3QNA7SH 2. How do you get #monkeypox? Through close contact, e.g. hugging, kissing, sex, or contaminated materials, e.g. shared linen or cutlery. It’s much harder to contract monkeypox than #COVID19. The @nicd_sa's Jackie Weyer explains it in this sound clip:

[Thread] JUST IN:
1. @healthza has confirmed that #JoePhaahla has repealed regulations 16A, 16B + 16C in section 90 of the National Health Act. What does this mean?
In short:
1. No masks
2. #COVID19 gathering rules = dropped
3. COVID entry requirements into SA = dropped 2. What does regulation 16 A say?
- You must wear a mask indoors
- You must wear a mask when using public transport

This has been repealed, so you no longer:
- Have to wear indoor masks
- Have to wear masks when using public transport

🧵JUST IN: 1. From Mon, 6 June, people of 50+ can get an extra #Pfizer #COVID19 vaccine booster 120 days after their previous booster. Technically, you can already get one from tomorrow (Sat), as the #EVDS went live tonight, but you’ll only receive an sms alert from Mon. 2. Can you choose if you want an extra #JnJ or #Pfizer booster? No. For this round, you'll need to take a #Pfizer booster (all SA’s #Pfizer jabs will have expired by the end of Oct, so this is one way of using them faster before then).

🧵1. It used to be straightforward to determine when we were in a #COVIDinSA wave. Everyone used the ministerial advisory committee’s formula. In 2022, things are a bit more complicated. Some researchers argue this method is no longer all that useful. bit.ly/3wkRRwv 2. If we use the MAC formula, the fifth wave started on May 7. But since these numbers alone no longer translate into curfews, lockdowns or liquor bans, @nicd_sa researchers believe a new benchmark may be necessary. bit.ly/3wkRRwv

🧵1. #JoePhaahla, #HIV:
- 8 million SAs = HIV positive in 2021
- Nr on #ARV's: 5.4 million, so there's a gap of over 2 million who are projected to be HIV positive but not on treatment.
- Main concern = spread amongst young people, especially young girls. 2. SA's policy = to provide #HIV treatment for everyone who tests positive to achieve viral suppression and reduce transmission.

🧵1. BREAKING: @SAHPRA1 has approved a 3-month extension of the expiry dates of #Pfizer #COVID19 shots when stored at -70 °C. @HealthZA says it's stored the 92,370 jabs that originally expired on March 31 at -70°C, so they'll now only expire on June 30th and can still be used. 2. Why are there new expiry dates?

#COVID19 jabs have only been around for +/- 1.5 years. Manufacturers can only test if they stay stable 4 extended periods of time as the time moves on. They've now established that Pfizer jabs can be kept at -70°C for 12 (instead of 9) months

🧵1. Is SA in a 5th #COVID19 wave?
@ProfAbdoolKarim: It’s too early to tell. We don’t have reliable data 2 compare infections of the last 7 days with the previous 7 days. Why? SA = 2 holidays in the past week, so testing nrs = down + can’t reliably be compared 2 the previous wk. 2. Why do we need to compare data of the last 7 days with the previous 7 days?

- For a 5th wave the 7-day moving average would have doubled every 2-3 days (so we would have had 10,000+ cases by now)
- But we’ve seen only a 52% increase: from 3,097 (April 24) to 4,693 (May 1)

🧵1. It's been 2 years of mostly only #COVID19 reporting. What has the pandemic taught me about journalism?

Lesson 1: Accurate information is pretty useless if people don't understand it. Explanatory journalism should be specialist field: bit.ly/36xvxWm Lesson 2: Pandemics like #COVID19 make things happen faster. But to speed things up you need more hands and skills — you're going to get nowhere on your own.

The power lies in journalism oranisations sharing skills and resources. So learn to work together, or miss the bus.

🧵1. What will a potential next #COVID19 variant of concern look like?
We dunno but it's unlikely 2 look like #Omicron, Beta/Delta, unless it arrives only when immunity from Omicron infection = waned
Why? Omicron infection = good immunity @ itself, Beta, Delta 2. Since #Omicron = spreading so fast + widely vs. past variants of concern, there are many vaxxed people who became infected with omicron and now have good immunity 2 all existing variants of concern. Similar immunity = evident in unvaxxed people with past Omicron infection.

🧵1. Will SA see a 5th wave?

1. @ProfAbdoolKarim says likely, but we don’t know if it'll be big or small. What we do know, is that we will almost certainly see a new variant. Each wave in SA has been driven by a new variant.

So what will a new variant look like? (next tweet) Image 2. What will a new variant look like (let’s call it Pi)?

We dunno.

But for Pi to become the dominant variant it will have to be more transmissible than #Omicron, or it won’t be able to replace/out-compete it (if they were athletes, Pi would need to run faster than Omicron). Image

🧵1. What's happening with #COVID19 in globally + in SA?
@Dr_Groome, @nicd_sa:

- Europe's had a relatively big 4th #Omicron wave, which seems to have stabilised
- Western Pacific countries (Hong Kong, China, Singapore) have seen huge increases in #COVID infections 2. Which variants caused a spike in infections in Western Pacific countries?

@Dr_Groome: Mostly #Omicron and here and there #Delta. So new variants haven't been the cause.

🧵1. It's @SAHPRA1's job to ensure only meds that are safe/effective are used in SA. What does that mean?

Mark Blockman, Sahpra:
It means Sahpra looks out 4 common side effects + more rare adverse effects that the manufacturer reported + new ones that emerge after registration 2. How does @SAHPRA1 review meds?
1. They look at data submitted by drug companies
2. They look at data published in studies about the meds
3. They look at decisions of other credible regulators

🧵1. Until when will you be able to get a #Pfizer #COVID19 jab in SA?

Most likely only until July 31st, says @HealthZA. After that only #JnJ will be available.

Why? SA has received all the doses it's procured from Pfizer and the last batch expires on July 31. 2. How many #COVID19 jabs has SA received?

Total: 60,6 million

- #Pfizer: 39,272,220 (this includes US donations and jabs we got via #Covax)
- #JnJ: 21,333,840 (we also got 500,000 for #Sisonke1 + 250,00 for #Sisonke2)

[Thread] 1. What's happening with #COVID19 hospital admissions in SA?

Waasila Jassat, @nicd_sa:
- Over the past 14 days, admissions have decreased between 18% and 59% in all provinces 2. Your risk of hospitalisation due to an #Omicron infection is about 50% lower than in Wave 1,2,3 in SA (the risk for each wave = slightly different)

Most admissions in Wave 4 (#Omicron) = people between 20 and 39 years. In Wave 1,2,3 = admissions of people between 40 and 70.

🧵1.What's happening with #COVID19 infections in SA?

@Dr_Groome, @nicd_sa:

- Our #Omicron wave is over
- There was a small uptick when schools and colleges opened and restrictions were also eased, but infections are now down to "in between wave" levels 2. What version of #Omicron is dominant in SA?

1. BA.2 (the version that's now spreading around the world, as opposed to BA.1, the original version)
2. BA.2 (dark orange on pie charts) = more transmissible, but SA data shows it doesn't make people sicker than BA.1
