Omicron thwarts some of the world’s most-used COVID vaccines
Inactivated-virus vaccines elicit few, if any, infection-blocking antibodies — but might still protect against severe disease.
The world’s most widely used COVID-19 vaccines provide little to no protection against infection with the rapidly spreading Omicron variant, laboratory evidence suggests.
Inactivated-virus vaccines contain SARS-CoV-2 particles that have been chemically treated to make it impossible for them to cause an infection. Stable and relatively easy to manufacture, such vaccines have been distributed widely as part of China’s global vaccine diplomacy…They include those made by China’s Sinovac and Sinopharm, which together account for nearly 5 billion of the more than 11 billion COVID-19 vaccine doses delivered globally so far…
…recipients of inactivated vaccines, although not necessarily protected against infection by Omicron, should still be shielded from the worst ravages of COVID-19 triggered by the variant…T cells destroy infected cells; B cells remember past infections and strengthen immune responses for the future; and binding antibodies contribute to viral control… [end quote]
It’s early days with Omicron so it will take months to get a real answer from populations. And, of course, a new variant could pop up any day now.
China and India provide a huge amount of products that are exported to the U.S. We often think of consumer goods, but chemicals and pharmaceuticals are also very important. If widespread illness in these giant countries shuts down manufacturing, U.S. inflation will spike and some products may be unavailable. This is a Macro risk that could impact the markets as well as a Micro risk that could impact households.

If inactivated virus vaccines are ineffective, does that imply that people who had been infected with early live viruses also have no immunity? So all the vax deniers in Florida, for instance, who think they are now immune, and pushing the state toward herd immunity, because they had an earlier variant over the last two years, aren’t, and are going to go through the loop again?

They have, They are, they will.
However there are some things working in their favor as hospitalization are much less per 1000 infections.
Also, Florida is past peak.

125996 on January 10th vs 54994 on January 13th looks like an improvement, but that is a pretty short time span. Might want to wait a bit before hitting the bars unmasked and unvaxed for a victory lap.
All the holidays have been playing havoc with data collection in Michigan. Reporting will be down again Monday for MLK day.
But there are a heck of a lot of people in the hospital being treated for covid, instead of fueling the economy.

Good question. Only actual data will answer it, which will take time.

This is Florida. Even the armed robbers don’t west masks in bars.
In the mean time we are sitting on the balcony sunning in the 60 degree weather. We will be driving down to pier park to walk out on the pier. The water is super clear and the tourists are no where to be found.

Not really. The danger is mostly for those who have not had a vaccine or gotten COVID19. COVID19 was a “novel virus,” which means that no one’s body has seen anything like it before. When it takes our bodies to recognize there is a problem and mount a defense, a novel virus can reproduce and cause major damage. Being infected or injected with anything similar to COVID19 has given the body a “heads up, this doesn’t belong here” warning and a much quicker response time. Many people have been vaccinated, and omicron will care for the rest. IMHO this is the beginning of the end for COVID19 as we know it. There will be future outbreaks, and rich countries will still have Pfizer and Moderna to tailor boosters to the varients. But, to me, things are looking up.
Now, if someone could explain to me the huge sell-off of Moderna, a company that helped save the developed world’s collective arses…

A federal judge in Texas blocked the Biden administration from enforcing its coronavirus vaccine mandate for federal workers on Friday, citing the outcome of last week's Supreme Court ruling that nullified the administration's vaccine-or-test requirement for large employers.
