Omicron infection (UK data):

Natural immunity (prior infection) (4%-67%) slightly better than Pfizer 2-vax (-6% to 57%).

Hybrid immunity (prior infection & Pfizer 2-vax) (36–75%) slightly worse than Pfizer 3-vax (41–75%). This might be due to fading of immunity.

Best is hybrid immunity with booster (prior infection & Pfizer 3-vax) (56–82%)

For 95–97% protection, we probably need Omicron-specific vaccines (Pfizer is scheduled for Mar 2022. They are guessing 100 days needed to ramp up large-scale production).

No vaccine or previous non-Omicron Covid infection helps much with Omicron infection.

Omicron is too different.

Even Pfizer 3-vax & one previous infection is only 56-82%. Reduces infection by 2/3...which you can easily beat with distancing or N95 masks.

Current Covid vaccines are based on 25–26-month-old extinct Covid variants. Flu vaccines are updated yearly.

We're very lucky the 1st crop of vaccines worked so well versus Delta. Luck ran out with Omicron.

We should PLAN for the next variants.

Be PROACTIVE rather than reactive.

Be ready to switch vaccines in less than 100 days. Make small batches in 1–2 weeks to give to healthcare workers.

Hope for the best, but plan for the worst.

Omicron in Israel: 4th dose doesn't work well.
We’re lucky the 3rd dose of vaccines designed for extinct 25–26 month old viruses had some effect. We need the March 2022 Omicron-vaccines from Pfizer and Moderna…

Personal Opinion :

One catastrophe is very real, and the other is contrived, and faked and zombified.

We don’t get to arbitrarily decide when #Covid19 is over. It’s over someday only through our personal actions & policies to protect our community. 

P/s..   3,000+ Americans died of COVID yesterday.

I Had Never Felt Worse’: Long Covid Sufferers Are Struggling With Exercise

By Melinda Wenner Moyer
Feb. 12, 2022

When Natalie Hollabaugh tested positive for Covid-19 in March 2020, her recovery felt extremely slow. Eighteen months later, she was still suffering from a litany of symptoms, including fatigue, shortness of breath, headaches and joint pain. She saw a cardiologist and a pulmonologist, who both ruled out other health problems, she said. And they advised her to start exercising, suggesting that some of her symptoms may have been a result of being out of shape. So Ms. Hollabaugh dutifully began using an exercise bike, speed walking on a treadmill and walking her dogs several miles a day.

But instead of helping, her new exercise regimen only exacerbated her symptoms. “I had never felt worse,” said Ms. Hollabaugh, 31, a lawyer who lives in Portland, Ore. She found she had to start taking daily naps, that her heart rate would skyrocket even when she was at rest and that she was so tired she couldn’t concentrate.

As one of the many Americans suffering from long Covid, a condition characterized by new or lingering symptoms that can be felt for months after a coronavirus infectionMs. Hollabaugh is not alone in experiencing setbacks with exercise. Natalie Lambert, a biostatistician and health data scientist at the Indiana University School of Medicine, has collected self-reported data from more than a million long Covid patients through a collaboration with Survivor Corps, a Facebook support group for Covid survivors. Patients frequently report that their doctors have advised them to exercise, she said — but many say that when they do, they feel worse afterward.

“The research that I’ve done has shown that inability to exercise is one of the most common long-term symptoms,” Dr. Lambert said. Some people are simply too tired to exercise, she said, while others experience debilitating symptom relapses like increases in fatigue, brain fog or muscle pain. This worsening of symptoms after engaging in even just a little bit of physical activity — what is sometimes called “post-exertional malaise” — seems to be common among long Covid patients. When researchers performed an online survey of 3,762 people with long Covid, as part of a study published in August, they found that 89 percent reported post-exertional malaise.
