Vaccine evasion by Delta - seeing is believing. Good part is the vaccinated people (RNA vax) are having mild disease so farhttps://twitter.com/romeo_ph20/status/1407307271466479622 …

Vaccinated are often asymptomatic, but many of these are transmitting. Suggests the 6-fold lower potency of vaccine-elicited antibodies on Delta does matter. Good news: protection against severe disease Bad news: virus continues to mutate and transmit to the unvaccinatedpic.twitter.com/fjfL6UWjes
Granted the above may not be representative of other places (or even Singapore); we'll have to wait and see
And Delta is now the predominant strain in the US. Projections were for mid-July. Instead happened 2 weeks early, and only 5 weeks after introduction. @alexbolze via @ScottGottliebMDpic.twitter.com/EfwrFz51mV
Take-home message: No more sheltering from virus among the vaccinated. If you want protection, get your own arm jabbed.
As others have pointed out, the other message is to continue masking in crowded or indoor public spaces even if you're vaccinated of you want to avoid transmitting the disease to others. Made the point in one of the earlier replies. Also more info belowhttps://twitter.com/michaelzlin/status/1410495608268328962?s=20 …
Starting to get academic research reports on RNA vax evasion by Delta. Here 6 vaccinated people got sick. 2 received Covaxin, 4 received RNA vaccines. As they were symptomatic you can be sure they were contagious. 1 Covaxin died, 1 RNA was hospitalizedhttps://twitter.com/michaelzlin/status/1411959060774080514 …
Can the source of this be verified? Do we know the time frame of the vaccinations, including if this was fully tracked when classifying as "vaccinated"? How many of the "cases" are false positives known to occur with asymptomatic vaccinated?
The source (http://Covid.viz.Sg ) is compiled with the data the Singapore Govt releases daily about every case. The contact tracing here is extremely detailed and it includes date the person received their vaccination (Pfizer or Moderna).
@ChristosArgyrop Who’s gonna make the call? Herd immunity as an exemplar is plausibly impossible to get to now. It would appear to be easily disprovable with small subsets like @michaelzlin’s. The public health waffling has to end.pic.twitter.com/eC1qMX2BjX
There is no need immunity through infection. It'd be *over* now if we had used NPI to limit repeated cycles of infection (which generate the variants) and keep the virus in its initial form so that vaccines could kill it off. Rather elementary Dear Watson @fitterhappierAJ
