NEW VARIANT—a new #SARSCoV2 variant C.1.2 just identified in South Africa & several countries, with concerns it could be more infectious and evade vaccines.#C12 also has mutation rate that is nearly **twice as fast** as the rate of the other variants.

BREAKING—The
@WHO announces that new#SARSCoV2 variants will be named after major stars and constellations once they run out of Greek alphabet letters. Examples like “Virgo variant”, “Orion variant”, etc.

There are also solid facts to share, not just emotions:
Kids can get covid
Kids can get #LongCovidKids transmit #SARSCoV2No masks in schools
Hardly any other mitigations
Kids who’re household contacts of acute cases can still attend school https://www.bbc.com/news/education-58394420 … -
If you have
#LongCovid and been denied care or diagnosis because you had no covid antibodies detected in your blood, show this paper as evidence that some people infected with#SARSCoV2 don’t develop antibodies. https://wwwnc.cdc.gov/eid/article/27/9/21-1042_article … -
Study from USA finds no evidence of increased severity of infection with Delta compared to previous variants of
#SARSCoV2 (% of PICU admissions and length of stay actually slightly lower with Delta) However big increases in rates of infection in low vaccination areas https://twitter.com/cdcmmwr/status/1433840991421800451 …

Have you met C.1.2? Our newest addition to the
#SARSCoV2 variants list? It emerged in South Africa, & has so many mutations that it seems to be, "accelerated evolution in a single individual with prolonged viral infection through virus-host co-evolution." https://www.medrxiv.org/content/10.1101/2021.08.20.21262342v2.full.pdf … -
6) Recently, another study found that Moderna’s vaccine had **2-fold lower risk of breakthrough**
#SARSCoV2 infections compared to Pfizer’s in a review of people in the Mayo Clinic Health System in the U.S. from January-July. A preprint. But solid study. https://www.medrxiv.org/content/10.1101/2021.08.06.21261707v2.full.pdf …pic.twitter.com/WNpgao9CQ2

Preexisting cross-reactive T cells against
#SARSCoV2 enhance SARS-CoV-2 immune responses upon infection & vaccination, a new study shows. These cells’ cross-reactivity decreases w/ age, which may help explain the incidence of severe infection in elderly https://fcld.ly/s5lobdg pic.twitter.com/hu8seWj4vO

I have just learned that my younger brother who is visiting Pakistan has been infected with
#SARSCoV2. It's a breakthrough infection. He was asymptomatic & doing just fine. My entire family in Pakistan was tested & the results came back -. Vaccines do work. Please get vaccinated. -

14/The role of *salivary* antibodies in protection against
#SARSCoV2 is unknown. Surveillance of salivary antibodies could provide critical insight into who is at highest risk for breakthrough infection post vaccination, as well as helping to optimize protection against the virus pic.twitter.com/YLEYOxJ6Bk

Elegant work published today
@SciImmunology that could never be done in humans to dissect out each component of the adaptive immune response to#SARSCoV2. Better than the paper is a thread by the master explainer! https://twitter.com/virusesimmunity/status/1433570048715763714 … -
SARS-CoV-2 prevents infected cells from signaling its neighbors, and shields them from T cell recognition and destruction. It also disrupts T cell functioning by targeting MHC-I. Here I describe these immune suppression processes of the virus. https://www.forbes.com/sites/williamhaseltine/2021/08/30/how-sars-cov-2-evades-and-suppresses-the-immune-system-part-9/?sh=edccab8a5c59 …

Data from the UK now show that the
#COVID19 case fatality rate for Delta#SARSCoV2 variant is higher for fully vaccinated people (0.96%) than for unvaccinated people (0.24%). 60.7% of deaths are in the fully vaccinated.
