Vaccine front there looks to be more vaccines coming – https://www.theguardian.com/world/2021/apr/04/two-new-vaccines-on-the-way-with-more-to-follow-this-year

“The other jab due to arrive in the UK in the near future is being made by the US firm Novavax and uses genetically engineered cells, extracted from moths, to make pieces of coronavirus protein that will stimulate anti-Covid responses when injected into people. The company says it expects to be given approval in the US and UK next month and will manufacture its vaccines in 20 locations on four continents, which should help avoid cross-border supply issues. Novavax expects to be able to make 2bn doses of its vaccine this year.”

“The second vaccine likely to be ready for use in the UK by the end of the year is expected to be manufactured by France-based Valneva at its new manufacturing facility in West Lothian, Scotland. The vaccine contains inactivated Covid-19 particles that stimulate the body’s immune system into manufacturing antibodies that swarm round invading viruses and block their actions. The vaccine is still undergoing clinical trials. However, if approved, it is likely be rolled out around the country by the end of the year. The UK has ordered 100m doses”.

As we have been saying go outside get some sun – solution to pollution is dilution – also outside light kills – who would have known models can be wrong? https://arynews.tv/en/sunlight-destroys-covid-8-times-faster/

“A team of scientists is calling for further research into how sunlight inactivates SARS-CoV-2 after noticing a glaring inconsistency between the most recent theoretical and experimental results. UC Santa Barbara mechanical engineer Paolo Luzzatto-Fegiz and colleagues noticed the virus was inactivated as much as eight times faster in experiments than the most recent theoretical model predicted.”

“Short-wave UVC radiation has been shown to be effective against viruses such as SARS-CoV-2, even while it’s still safely enveloped in human fluids.

But this type of UV doesn’t usually come into contact with Earth’s surface, thanks to the ozone layer.

“UVC is great for hospitals,” said co-author and Oregon State University toxicologist Julie McMurry. “But in other environments – for instance, kitchens or subways – UVC would interact with the particulates to produce harmful ozone.”

In July 2020, an experimental study tested the effects of UV light on SARS-CoV-2 in simulated saliva. They recorded the virus was inactivated when exposed to simulated sunlight for between 10-20 minutes.

“Natural sunlight may be effective as a disinfectant for contaminated nonporous materials,” Wood and colleagues concluded in the paper.”

“This study found the SARS-CoV-2 virus was three times more sensitive to the UV in sunlight than influenza A, with 90 percent of the coronavirus’s particles being inactivated after just half an hour of exposure to midday sunlight in summer. By comparison, in winter light infectious particles could remain intact for days.”

“The researchers suspect it’s possible that instead of affecting the RNA directly, long-wave UVA may be interacting with molecules in the testing medium (simulated saliva) in a way that hastens the inactivation of the virus.

Something similar is seen in wastewater treatment – where UVA reacts with other substances to create molecules that damage viruses.

If UVA can be harnessed to combat SARS-CoV-2, cheap and energy-efficient wavelength-specific light sources might be useful in augmenting air filtration systems at relatively low risk for human health.”

However then we have the policy that promotes indoor gathering vs. outdoor – amazing to see this in Belgium – https://twitter.com/drdavidsamadi/status/1378289828417114113?s=19
