[Thread] 1.#ZweliMkhize: SA's decision to pause its J&J roll-out is not a knee-jerk reaction. It's a precautionary measure. I have consulted the SAMRC, the ethics committees that oversee the Sisonke study, the MAC and @SAHPRA1 about this decision.
2. #ZweliMkhize: The feeling of all the bodies I have consulted with has been that because this announcement came from the FDA, we would need to collate as much info as possible before we continue with our own roll-out.
3. #ZweliMkhize: SA's first batch of 1 million J&J jabs will arrive next week. The pausing of our J&J roll-out won't have a significant impact - we're hoping it will only be for a few days until we have enough information.

[Thread] 1. #ZweliMkhize says there is no evidence that J&J is linked to blood clots. SA is pausing its roll-out as a precautionary measure to find out if there is something to be concerned about before we proceed.
2. Helen Rees (Sahpra's chair): Vaccine safety is always at the top of our list. In the case J&J, the nr of blood clot cases is very low: 6 cases out of almost 7 million vaccinated people in the US. We need to find out if the cases are accidental or linked to the jab.
3. Helen Rees: This process is called a causality assessment. It's normal to do with new jabs. Why? In trials, jabs are tested on 1000s of people. When you roll them out, millions of people get them. So there's a chance for side effects you didn't see in the trial to occur.

[Thread] 1. VACCINE ARRIVAL UPDATES: According to #ZweliMkhize, J&J has confirmed that just over 1 mil #CovidVaccines will be delivered to SA between 22 + 24 April. They will all come from the local Aspen plant (previously we only knew they'd arrive in the 3rd/4th wk of April).
2. #ZweliMkhize: The 2nd and 3rd J&J #CovidVaccine batches in May and June (900 000 per month) will come from Belgium (the first batch will come from Aspen in SA), so delivery will be more complex. We'll get an exact delivery date within the next 2 weeks.
3. #Pfizer 1st batch of #CovidVaccines is likely to arrive in April. Next week, Pfizer will tell SA how many doses + also a specific delivery date (if there are no payment glitches). #ZweliMkhize previously said we'll get 5.5 million doses between April + June.

[Thread] 1. The two jabs — #JohnsonandJohnson and #Pfizer — that SA will (so far) use in its national #CovidVaccine roll-out have now both been approved for use by our regulator, @SAHPRA1. So what now — when will you get your jab?
2. The next batch of J&J jabs (200 000) will arrive on 10 April. But these #CovidVaccines are for use in SA's Sisonke trial (our implementation study) and only #HealthWorkers can be vaccinated with them. They can’t be used for our wider, national roll-out.
3. Our 1st commercial batch — 1 million J&J jabs — will land in the 3rd/4th wk of April. The diffs between this batch + the Sisonke jabs: we’re paying for this batch + can use it outside of a research setting. The Sisonke jabs came for free but we can only use them for the study.

[Thread] 1. SA’s commercial #CovidVaccine roll-out will start in April, the government says. Which jabs will we use? For now, J&J (the same jabs used in the Sisonke implementation study) and Pfizer. We will also consider Moderna, but no deals yet.
2. Why are we using J&J + Pfizer? SA trials showed J&J works well against the new variant, #501YV2. Pfizer hasn’t been tested in SA, but lab tests suggest it has reduced efficacy @ 501Y.V2. But because the efficacy is high (95%), even the reduced efficacy will provide protection.
3. Have the jabs been approved for commercial use in SA? Pfizer received emergency use authorisation (called Section 21 approval in SA) in March. J&J has not yet been approved (only for research), but on Monday @SAHPRA1 said an announcement will be made “within the next days”.

[Thread] 1.#CyrilRamaphosa: In SA we are not yet ready to return to normal life because of #COVID19. For the 2nd year we will have to limited our interactions during the Easter period. Over the last year we have recorded more than 1.5 million cases.

2. #CyrilRamaphosa: For the past 2 weeks, our cases stayed stable and hospitalisations and deaths have declined. This is because South Africans have largely abided by the restrictions put in place.
3. #CyrilRamaphosa: Phase 1 of our vaccination programme for health workers will be completed within 3 months (it started on Feb 17).

[Thread] 1. How are we doing with our J&J #Covid Sisonke study vaccinations in provinces? Most vaccinations have happened in Gauteng, KZN and Western Cape. Gender breakdown: 74% of jabs have been given to women #HealthWorkers. Source: @LindaGailBekker @DTHF_SA webinar, 13 March
2. Have we seen side effects/adverse events in SA's Sisonke #CovidVaccine study? 2.1% of "vaccinees" have reported minor adverse events, e.g. swelling/redness where they've been injected or mild headaches/body pain. Of those, about 96% have recovered or are busy getting better.
3. What side effects should you expect when injected with the Johnson & Johnson #CovidVaccine? Pain/swelling (at the site of injection), chills, tiredness, headaches. Most of these symptoms disappear within two days.
