Purely as food for thought, this recent article about a recent unexplained, or expected, rise in infections in a highly vaccinated island nation.

The surprising part is that 37% of the new cases are people are fully vaccinated.

Clicky, clicky.....

Thanks, JaxDad - this is a bit alarming since the USA just announced that we can take those masks off (paraphrased). And on last night's news, they said the Nurses' Union says that's a bad idea. I realize we are all participating in a study of the pandemic indirectly - but for myself, I'll keep my mask handy, and keep watching the data for new cases.

The article indicates that most were vaccinated with the Sinopharm vaccine.

WHO: The Sinopharm COVID-19 vaccine: What you need to know

Quote:

How efficacious is the vaccine?

A large multi-country Phase 3 trial has shown that 2 doses, administered at an interval of 21 days, have an efficacy of 79% against symptomatic SARS-CoV-2 infection 14 or more days after the second dose. Vaccine efficacy against hospitalization was 79%.

The trial was not designed and powered to demonstrate efficacy against severe disease in persons with comorbidities, in pregnancy, or in persons aged 60 years and above. Women were underrepresented in the trial. The median duration of follow-up available at the time of evidence review was 112 days.

Two other efficacy trials are under way but data are not yet available.

Does it work against new variants of SARS-CoV-2 virus?

SAGE currently recommends using this vaccine, according to the WHO Prioritization Roadmap.

As new data becomes available, WHO will update recommendations accordingly. This vaccine has not yet been evaluated in the context of circulation of widespread variants of concern.


The devil is in the details and the popular press is prone to gloss over these details. Most were vaccinated with a vaccine shown to be less effective against the original variant than the mRNA vaccines and it is not yet known how effective it is against the new variants.

This is from the news article.
Quote:

To date, among those who a have received two doses, 57% have received Sinopharm and 43% Covishield, the Seychelles’ health ministry said. It’s unclear which vaccine had been given to individuals who had been fully immunized but then tested positive for Covid.

Mark gives a good perspective of this news report from the Seychelles.

Reports of breakthrough infections in this country have also been reported in people fully vaccinated. Remember that the efficacy was reported at 95% which means that we could expect 5% breakthrough infections.

The CDC has changed their reporting methodology and now just report hospitalized breakthrough cases. As of May 10, there were 1349 out of 115 million fully vaccinated people. CDC Breakthrough cases

I understand the relaxation of mask mandates. The chances of a fully vaccinated individual currently acquiring COVID and requiring hospitalization is miniscule. But NOT ZERO.

I think part of the reasoning had to be to create an inducement to get the vaccine for hesitant individuals.

Sorry if I wasn’t clear enough, the fact that they were jabbed with the Sinopharm vaccine and then got sick WAS my point.

Sure the article was about a tiny island nation, but what about the 1.4 billion people in China and who knows how many more around the world that are also going to get that vaccine?

Will those people continue to be a threat of reinfection to the rest of the world?

The article indicated those vaccinated received one of two vaccines and the public health officials did not know which vaccine was taken by the vaccinated people who then got sick. It also indicates that most of those hospitalized had not been vaccinated. The unvaccinated population is the greatest risk for continuing waves of Covid-19 infections and the development of new variants.

Are cattle farmers better protected from COVID-19?

Not able to open the article; but saw on TV a few days ago, (PBS story on the immune system) of twin sisters in their 20's - one was a "girly-girl"; the other loved horseback riding and was forever at the barn, cleaning, brushing, etc. The Horsey-girl mentioned that she never got sick, while the Girly-girl seemed to catch everything.

I DO believe exposure to dirt/bacteria/grunge keeps our immune systems tweaked :-)

Sorry, I could not find another source of this new article. Here is a summary.

Early on, medical and veterinary scientists indicated that people cannot be infected by Bovine Respiratory Coronavirus and therefore, those exposed to this animal disease would not have immunity to Covid-19. A local MD and veterinarian near Staunton VA noticed that those who work around cattle were less likely to get severe cases of Covid-19 than those who do not work around cattle, this was also true within the same family (daily exposure to cattle correlated to less severe cases of Covid-19). The MD and veterinarian formed a hypothesis that like with smallpox (those exposed to the related cowpox had some immunity to smallpox), exposure to BCov lead to the development of antibodies to BCov (without getting infected like with a vaccine) and these BCoV antibodies had some cross reactivity to SARS-Cov-2. All coronaviruses have spikes (defining characteristic of these viruses) and RBDs which bind to the ACE2 receptor.

This is a very reasonable hypothesis. Medical science has been producing antibodies against human proteins and human infecting viruses by inoculating other species (mice, rabbits, sheep, etc) with the human protein or relevant portions of the human infecting virus. The resulting antibodies have names like: "mouse anti-human PSA" and these are then used in human immunoassays (example: PSA blood test) and immunotherapies.
