BREAKING [Thread]
From Wed, 23rd Feb, you can: 1. Get a 2nd #Pfizer jab 21 days after a 1st jab (previously = 42 days) 2. Get a Pfizer booster (3rd jab) 3 mnths after a 2nd jab (previously = 6 months) or choose 2 have a #JnJ booster after 2 #Pfizer shots (boosters = only for 18+)
2. From TOMORROW, Mon, 21st Feb, people of 18+ who received 1 #JnJ jab can:
- Choose to have a #Pfizer booster (instead of a 2nd #JnJ shot [booster] after 1 JnJ shot), in other words, you'll be able to "mix and match"
3. What should you do if a site has only 1 brand of #COVID19 vaccine available?
@HealthZA: 1. You should go with the same jab that you got 4 vaccination as a booster (or look for a different site) 2. Homologous boosting (booster = same as your other doses) = preferred
4. Confused? Here's a great table that explains the #COVID19 vaccine changes:
5. What else has changed?
If you received your #COVID19 jabs in ANOTHER COUNTRY, you will soon be able to get your BOOSTER dose in SA — the #EVDS is being updated to allow for this. Not date for this yet.
6. One more change: 1. You can now get a #COVID19 jab at the same time as another vaccination (e.g. a flu or #HPV jab). 2. Previously, @healthza said you had to wait for 2 weeks after a #COVID jab before getting a different type of jab. But that's no longer required.
7. SUMMARY: 1. You can (so far) only mix + match with BOOSTER #COVID19 vaccine doses in SA, not with primary schedule shots (if you had #Pfizer you need to get a 2nd Pfizer shot, you can't get a JnJ jab as a 2nd shot, only as a booster) 2. Boosters = only approved for 18+ in SA
8. What about #HealthWorkers = both vaccinated + boosted with #JnJ — can they get a #Pfizer booster (so a 3rd dose)? @healthza:
@heatlhza = asked the vaccine MAC for guidance. So far, the EVDS has not been programmed 4 this. But depending on the guidance, that could change.

1. South Africa, Egypt, Kenya, Nigeria, Senegal and Tunisia are the 1st six countries who will receive technology transfer to produce #mRNA vaccines as part of the WHO's mRNA tech transfer hub.
2. What is tech transfer? It's sharing the "know how" of how to produce jabs, in addition 2 the recipe. It's a little like putting together a piece of DIY furniture: You need the different pieces to put together but also instructions on how to do it plus the tools to do it with.
3. What is the WHO's mRNA transfer hubs?
1. One of the hubs will be based in SA 2. The hubs in low- and middle-income countries will work with local companies, scientists + academics to figure out the methods for making specific jabs
BREAKING: [Thread] 1. @SAHPRA1 has given emergency authorisation for the importation of the #COVID19 treatment molnupiravir (provided by the drug company MSD)
2. What is molnupiravir? It's an antiviral pill that can lower your chances of falling seriously ill or dying from COVID
2. With which conditions does @SAHPRA1's authorisation of molnupiravir come?
1. The pills can initially only be imported for 6 months 2. There's a limit on the nr of pills that can be imported (nr = not mentioned in the press release) 3. Only people of 18+ can use it
3. How well does molnupiravir work?
If taken within 5 days after the 1st #COVIVD19 symptoms, it can: 1. Lower the risk of hospitalisation by 30% in unvaccinated, high-risk COVID patients 2. Reduce the risk of dying from COVID by 89%
[Thread] 1. How fast is BA.2 (a subvariant of the #Omicron variant) spreading in SA and is it making people sicker than BA.1 (the original form of #Omicron)?
2. What is BA.2? 1. It is a new form (scientists call it a sub-variant or new lineage) of the #Omicron variant 2. BA.2 has been detected in 145 countries 3. Data from the UK and Denmark suggest BA.2 is more transmissible than BA.1 (so it spreads faster)
3. How widely has BA.2 spread in SA? 1. BA.2 (one of the new forms of #Omicron) has taken over from BA.1 (original form of #Omicron) 2. Look at the graph:
- Light orange = BA.1
- Dark orange = BA.2
JUST IN: 1. [Thread] 1. 63 civil society orgs in SA have written an open letter to #Moderna to immediately withdraw the mRNA vaccine patents it has filed in SA 2. Why? They says the patents pose long term barriers to local production of #mRNA vaccines
2. What about #Moderna's #COVID19 jab? 1. Moderna = pledged not 2 enforce patents on its jab 4 the duration of the pandemic 2. But the company = filed several patents with broad claims in SA, prompting fears it will begin enforcing patents while COVID = still endemic in Africa
3. Has #Moderna agreed to join and help Africa with local production via the WHO's #mRNA hub?
No. They're refusing to be part of the hub or to share their know-how. That's why SA's Afrigen has had to decipher their #COVID19 vaccine recipe. bit.ly/3Js0YiF
[Thread] 1. Why are #Omicron infections in SA decreasing slower than what they increased? @Dr_Groome of @nicd_sa: 1. 4th wave’s downward slope = plateaued. We’ve had similar nrs of new #COVID19 cases for 3 weeks 2. 4th wave downward slope (graph) = not as steep as upward slope
2. Is the number of #COVID19 infections per 100 000 people increasing in any province?
1. Yes, it's increasing in MP, FS, GP, LP (if we compare the past 7 days with the previous 7 days) 2. In coastal provinces (WC, KZN, EC) cases are decreasing
3. Is the % of #COVID19 tests coming out positive (test positivity rate) increasing in any province?
1. Yes, over the past 3 weeks the test + rate has increased in GP, FS, MP, LP (black line on graph) 2. But the test + rate declined in coastal provinces (WC, EC, KZN) and NC.
