NEW: [Thread] 1. #JnJ 2day announced (via a press release: bit.ly/3AFFCu0): 1. JnJ's #COVID19 jab = more effective when given as a double shot, 56 days - 6 mnths apart (vs. just 1 shot) 2. The efficacy of 1 shot doesn't wane, but a booster shot makes it more effective.
2. When a 2nd #JnJ shot is given 56 days after the 1st one, the 2-dose combo provides:
* 100% protection @ severe #COVID19 14 days after the 2nd shot
* 75% protection @ symptomatic (moderate to severe/critical) COVID19 in the countries where the jab was tested
3. When a 2nd/booster shot of the #JnJ#COVID19 jab was given 56 days after the first shot, trial participants' antibody levels rose to 4-6x times higher than after just one shot.
1. The aim of vaccination certificates = not to punish people, but to protect each other 2. Vaccination certificates will allow SA to introduce policies to open up more activities, e.g. larger sports events, for vaccinated people
2. #Phaahla: Vaccination certificates will allow vaccinated people more access to activities than unvaccinated people. But it won't deprive unvaccinated people from accessing essential services, e.g. health clinics. You won't need certificates to access such services.
3. How will vaccination certificates be accessed? #Phaahla: 1. A link from which you can download your certificate will be sent to your phone (you can only download it if you have a smart phone) 2. Your vaccination site will be able to print you a certificate
[Thread] 1. #Phaahla: Vaccinations of people below 18: 1. #Pfizer has been approved for use on people of 12+ 2. SA, for the next month or two, will remain focused on vaccinating people of 18+ (higher risk people) 3. Main priority = 50+ (most vulnerable) before our 4th wave
2. #Phaahla: 1. We're not ignoring the fact that #Pfizer has been approved for use by people below 18 yrs + schools want learners vaccinated 2. We're hoping by the end of Oct we will have covered enough adults to then review our policy + consider vaccinating people of below 18
3. #Phaahla: 1. @healthza believes it will be irresponsible to "start running around" vaccinating teenagers before we haven't reached enough adults (high risk group) 2. Goal = to have 50% of people of 50+ vaccinated first (currently = at 30%).
[Thread] 1. #Phaahla: SA's 3rd #COVID19 wave has been considerably longer than other waves: 1. First wave = 87 days 2. Second wave = 95 days 3. Third wave (so far) = 120 days
2. #Phaahla: When compared to the previous 7 days, overall new #COVID19 cases are down by 35%. The positivity rate (the % of tests that come out +) is down by 9.5% to an average + rate of 9.3%. That brings us closer to the WHO's recommend, "safer" +rate of 5%.
3. #Phaahla: Active #COVID19 cases are going down. The WC and KZN still have the highest numbers of active cases, but they're slowly coming down.
[Thread].1. How is Northwest province doing with #VaccineRollOutSA?
* To reach 70% of adults by Dec, NW needs to do 20 000 jabs six days/week
* Where are they now? NW is doing 13 000 jabs/week
* Biggest challenge = vaccine hesitancy
2. How many #VaccineRollOutSA sites does NW have?
* 55 fixes sites (42 public, 13 private)
* 200 outreach sites
* NW has all the required equipment and also enough staff and funds to vaccinate all adults who needs a vaccine
3. Vaccine hesitancy in NW province = biggest problem. NW hlth dpt says the graph below shows that it's particularly difficult to get people to visit sites that are open over weekends, so there are huge dips in weekend vaccination numbers.
#Phaahla: [Thread] 1. BREAKING 1. In about 1 week, vaccinated SAs are likely to be issued with digital vaccination certificates 2. The certificates can be uploaded onto smart phones + will be printable 3. You can only get a certificate if your vax details = recorded on the #EVDS
2. #Phaahla: SA doesn't currently require vaccine passports for travelers coming into the country. We only require #COVID (PCR) test results not older than 72 hours.
3. #Phaahla: Digital vaccination certificates for vaccinated people in SA will:
* Protected from fraud, as far as possible
* Be in line with WHO requirements (WHO is standardising vaccine certificates for all countries to decrease the possibility of fraud)
[Thread] 1. #Phaahla: There has been a 24% drop in new #COVID19 cases, compared to the previous 7 days. But the WC (23.6% of new cases), NC, FS, KZN still have relatively proportions of new cases.
2.#Phaahla: Hospitalisations = decreased by 10% vs. the previous 7 days. WC has the highest #COVID hospitalisation rate. The WC is followed by FS and GP. Cases in GP = drastically dropped, but because people take time to fall ill, hospitalisations = still high in the province.
3. Positivity rates (the % of tests coming out +) have decreased from 30% on mid-July to 12% on Thu. Gauteng has the lowest + rate = 4.4%. GP = the only province with a + rate below the WHO's recommended rate of 5%.
[Thread] 1. Are fewer vaccinated than unvaccinated people of 60+ in WC being hospitalised for #COVID19 + dying of it?
YES, FAR FEWER.
1. Hospitalisations: Out of 729 admissions, 699 (96%) = unvaccinated 2. Deaths: Out of 292 deaths, 287 (98.3%) = unvaccinated.
Data: 14-20 Aug
2. Look @ the note @ the bottom of this @WestCapeHealth slide: "With thanks to Sanford Health Hospitals for concept". This is in reference to a slide with a similar template which Sanford Hospitals use for their data, which was also used to release Groote Schuur data this week.
3. #Antivaxxers falsely argued Groote Schuur Hospital data released on this template = untrue because it used a graphic that looked like Sanford Health Hospitals'. But @westerncapehealth confirmed the data as accurate + 2day released more data using a similar template.
[Thread] Why has @healthza not procured vaccines other than #Pfizer and #JnJ (so a third option)? @healthza's Nicholas Crisp: 1. There are 2 vaccines to choose from: AstraZeneca and Sinovac. 2. Both of these jabs have been approved for use by @SAHPRA1.
2. AstraZeneca: 1. We have data that it works @ the #Delta variant. 2. Availability = an issue, we're looking for a supplier with stock. Serum Institute in India = no stock. If we buy from a new manufacturer we need a certificate of good pharmaceutical practice = takes time.
* @healthza hopes stock may become available at the end of Sep or Oct
[Thread]. 1. The Overberg district has the highest #COVID vaccine registration rate in SA: 1. 96.7% of 60+ = registered 2. 84.5% of 60+ = vaccinated 3. What helped with success? Partnerships between the private and public sectors.
2. The Overberg district has daily meetings to identify which geographic areas have low registration rates and then specifically target those areas (example = table on the left).
3. How does Overberg convince people in areas with low vaccination registration areas to register? 1. Community workers go door to door 2. People on megaphones go into communities + read scripts that encourage people to get registered 3. Social media + WhatsApp groups
[Thread] 1. #JoPhaahla: Our 3rd #COVID wave behaves differently from the 1st + 2nd wave.
How? In wave 1 + 2, new cases decreased consistently after peaks. In the 3rd wave, it's not that clear cut. The 3rd wave seems to drag on longer.
2. #JoPhaahla: In July we saw a downward trend of new #COVID cases, but on 13 Aug cases started to increase again. This was not only a national fluctuation, but could also be seen in provinces, specifically, in EC and NC.
3. #JoPhaahla: In Gauteng, there is encouraging news. There has been a sustained downward trend of new #COVID cases.
Hint: When burger ingredients join forces, each 1's role = amplified.
2. The burger patty
Ground beef is the star of the traditional burger. Its scientific equal = raw data scientists collect.
But you can’t just slap mince onto a burger. You need a binder before you can call it a patty.
In research, a study protocol (rule book) = the binder.
3. What is the #SputnikV jab?
- It's a viral vector jab (like the #JnJ jab, it uses an adenovirus to sneak an unharmful form of the #COVID virus into your body)
- You get 2 doses (they're not the same)
- Sputnik is under review by Sahpra
[Thread] 1. How many #COVIDVaccines will SA receive in Aug?
Nicholas Crisp, @healthza: 1. We no longer have a supply shortage 2. The slide below shows delivery dates + doses. It takes a week for doses to get to sites after arrival (clearance, quality testing, distribution).
2. How many adults have registered for #COVID vaccinations?
Crisp: 1. Registrations have been disappointing 2. 9.2 mil (out of 40 mil = 23%) adults have registered 3. 60+ = age group with the largest % registered (3.5 mil out of 5 mil = 70%)
3. Crisp: 1. Vaccinations = slowed down by SA's vaccine shortage 2 wks ago (see slide) 2. We've lost momentum: We now have enough supply, but demand has decreased 3. There will defs be a 4th wave, but we don't know when + which variant will be dominant (could be a new one)
[Thread] Joe Phaahla: 1. Despite the downward trend in #COVID19SA cases, SA is still in its third wave. It's like a relay race: as cases in 1 province goes down, cases in another province take over.
2. Joe Phaahla: Cases in Gauteng are clearly down, but cases in the Western Cape have now taken over: over the last 7 days, the WC has taken the lead with the most new daily #COVID19 infections, active cases and hospitalisations.
3. Joe Phaahla: Nationally, SA's active #COVID19 cases have decreased by 7% over the past week and hospital admissions by 4.4%, so there is a little bit of relief on hospitals.
3. Gray: #Sisonke researchers used three sets of data to analyse the study's results: 1. 2 sets of data from medical insurers were used and one set of provincial persal data 2. Today Gray is only reporting on two sets of data
