TUESDAY AND FRIDAY ARE USUALLY THE MOST IMPORTANT COVID NEWS DAYS. I PLAN TO CUT BACK TO TWO OR THREE MAILOUTS A WEEK WHILE THINGS ARE QUIET. I ALSO PLAN TO KEEP MY MASK HANDY.
SUGGESTED BY A CERTAIN NORWEGIAN OVERSEER:
Two Therapies Effective Against Long COVID Breathlessness, Fatigue
Vanishing variants such as Gamma, Iota and Mu hold lessons for the future.
”… likely because Mu found itself competing with an even more formidable variant: Delta. Delta was not as skilled at dodging antibodies as Mu, but it was more transmissible. “So, in the end, Delta spread more widely…vaccinations and multiple waves of infection have changed the immune landscape. A highly immune-evasive variant should now have more of an edge, scientists said, which is likely part of the reason Omicron has been so successful…”
1. “…The WHO and other health experts continue to emphasize that full vaccination and booster doses provide the best protection against circulating and emerging SARS-CoV-2 variants. This study provides some evidence that immunity conferred by recent BA.1 infection and vaccination may be less effective against the emerging BA.4 and BA.5 subvariants; however, additional research is needed before we can have a clear picture of how well natural and vaccine-induced immunity protect against infection, symptomatic COVID-19 disease, and severe symptoms or death associated with the BA.4 and BA.5 subvariants…”
2. ”…epidemiologists have turned to different metrics to better estimate COVID-19’s impact, looking instead at hospital data to estimate severe disease levels in communities and strain on healthcare systems. Others are watching wastewater surveillance to help predict where and when outbreaks might occur. As the nation shifts its response from an acute emergency phase to a more long-term response, and as immunity from vaccination and natural infection wane, the country will continue to rely on these imperfect data to help inform individuals and jurisdictions about their current and future risks of contracting COVID-19….”
3. ”OMICRON-SPECIFIC VACCINES Global vaccine manufacturers are racing to update their vaccines to target the Omicron variant of concern (VOC) and its subvariant descendants. Although booster shots have been fairly successful in preventing severe outcomes from COVID-19, they have not been nearly as effective in preventing infection altogether as Omicron has swept many areas of the world. Moderna announced that it is aiming for a Fall release of its Omicron-specific mRNA vaccine booster. The company earlier this year began trialing various formulations of Omicron-specific candidates and stated recently they have identified at least 2 strong candidates for further trials and possible authorization. Pfizer also is set to launch human trials for its own Omicron-specific mRNA vaccine candidates soon…”
