#JoePhaahla: 1. 20 million+ vaccine doses in stock 2. There's been an increase in take-up over the past week 3. But there's still a risk that 100,000 doses that will expire on March 31 won't be used in time + need to be discarded
2. #JoePhaahla: 1. SA is working with #COVAX to take up doses in SA that risk expiry before use and then return them later (so a kind of exchange programme) 2. Programmes right now specifically target the 18-34 age group where uptake is the lowest
3. Nicholas Crisp, @HealthZA:
More exact count of nr of #COVID19 doses in SA: 25 mil doses
- 13 mil = #Pfizer
- Pfizer = more difficult to store than #JnJ - once removed from low temperatures = limited shelve life
- All JnJ doses only expire in 2023
4. Nicholas Crisp:
- Pfizer = 7 to 9 months shelf life in central storage (at very low temps)
- Once Pfizer doses = removed from central storage and transported to sites, they're stored at lower temps, which reduce the shelf life
5. Nicholas Crisp:
- 1st #Pfizer batch that risks expiry before use: 100,000 doses (expiry = March 31st)
- This has been brought down from an original 400,000 doses that risked expiry by targeting the 18-34 year group via special programmes over the past 2 weeks
6. Nicholas Crisp:
- @HealthZA doesn't want to release the 100,000 doses that risk expiry on March 31st from central storage because if they then expire before use the dpt will have to destroy doses in many different sites (= logistically complex + expensive)
7. Nicholas Crisp:
- The dpt will only distribute the 100,00 doses that risk expiry (on March 31st) to sites if they're 100% sure those sites will be able to use them
- Instead, @HealthZA = distributing doses that will expire later + talking 2 countries/#COVAX 2 exchange doses
8. Which other #Pfizer doses risk expiry?
Crisp:
- No doses = likely to expire in April
- But 7 mil doses = expire in May, June, July (@healthza = trying to swop these doses with countries who need them now)
- SA won't be introducing any new #COVID19 vaccine brands for now
[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.
3. Even though there were more admissions among younger people during our #Omicron wave, people's risk of admission still increased with age. So the older you were, the more likely you were to get very sick with #COVID.
- 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
@Dr_Groome: 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
3. These graphs show how SA's #COVID19 cases have decreased (top) and how the BA.2 version of #Omicron has increased/spread (bottom).
[Thread] Have the new #COVIDV19 jab rules @healthza implemented in Feb resulted in a higher uptake?
- Early data = encouraging (🧵= details)
- What were the changes?
* 2nd #Pfizer jab = 21 days after 1st
* Pfizer booster = 90 days after 2nd
* #JnJ booster = 60 days after 1st
2. When did the changes kick in? 1. #JnJ: 21 Feb #Pfizer: 23 Feb 2. What happened?
Comparison of uptake on 16 Feb + 2 March (1 wk after new rules):
* Increases:
- EC: 113%, KZN: 64%; LP: 96% (private sites)
- WC: 66% (public sites)
- NC (93%) (public +private sites)
3. What changes did @healthza see in uptake in provinces before and after the new rules?
- Uptake in all provinces increased
- Largest increases
MP: 1.7%
FS : 1.3%
GP 1.3%
🧵1. Will SA vax kids between 5 + 11 years @ #COVID19?
- The vax MAC = not made a recommendation 2 @HealthZA. @SAHPRA1 = not approved vax 4 this group yet
- But if they say "yes" = no money 2 buy the jabs. Kids jabs = different from adult jabs. We can't use the ones we've got.
2. Do other countries vaccinate kids between 5 + 11 @ #COVID19?
- Just over a quarter of kids between 5 + 11 = vaxxed in the US
- UK = vaxxing vulnerable kids (for now)
- Sweden = only vaxxing kids vulnerable to respiratory diseases

3. What about our current #COVID19 vax stock?
- In total we've got 27 million doses
- 400,000 #Pfizer doses will expire on March 31
- 7 million #Pfizer doses will expire in June/July

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
