Coronavirus has mutated into more than 30 strains, say scientists in China

Scientists in China have discovered more than 30 mutations of the new coronavirus, which they say may partly explain why it has been more deadly in certain parts of the world.

Researchers from Zhejiang University said they had "direct evidence" that the virus "has acquired mutations capable of substantially changing its pathogenicity".

The study was written by a team including Professor Li Lanjuan, one of China's top scientists who was reportedly the first expert to propose a lockdown in Wuhan - where COVID-19 originated.

Samples were taken from 11 patients admitted to hospitals in Hangzhou, 470 miles east of Wuhan, between 22 January and 4 February during the early phase of the outbreak.

Using "ultra-deep sequencing", researchers identified 33 mutations of the new coronavirus - known as SARS-CoV-2 - of which 19 were new.

The deadliest mutations in the patients in the study had also been found in most patients across Europe, the South Morning China Post reported.

Meanwhile, the milder strains were the predominant types found in parts of the United States, such as Washington state, the newspaper said.

One mutation found in five patients involved in the research had previously only been seen in one case in Australia, according to the study.

The researchers said the findings indicate "the true diversity of the viral strains is still largely underappreciated"

I share your opinion that lab manipulation of the virus is highly questionable. Nature recombines viruses much more efficiently than does any lab. I relate to the mutation of the canine Parvovirus from cats into dogs back in 1978. It went around the world in less than a year due to it's R0 value and the small number of virions necessary for infection. Fortunately it is a DNA virus and an effective vaccine was produced. Back then we had to characterize viruses by morphological characteristics, molecular weight, protein coat composition, and nucleic acids. Virology and biochemistry has changed significantly since then.

The only way forward is to accept the risks and live life.

Interesting thing to have a closed mind by assuming others do...

We said months ago it was a virus. Viruses mutate. Yeah, how’s those regular flu shots working?

Influenza vaccines are made using three or four different strains of influenza, but are effective against a number of different clades, as long as they are still fairly close to the original strain.

But of course there does exist naturally acquired immunity for Influenza Type A and B, which would be protective against the four strains of influenza that are present in the vaccine (generally 2 Flu A strains (H1N1,H3N2) and 2 Flu B strains dependent on the season. But no health professionals are ever interested in testing individuals for the presence of these antibodies before recommending the flu vaccine. What other pharmaceutical do you know of is recommended without first knowing whether it is necessary?

...I’m pretty sure bioweapon people would start with a fairly accomplished killer from the outset..

now if they wanted to keep plausible deniability, (mistake) they might use something less lethal but damaging to the economy...like corona..no need to kill everyone just the economy..but getting caught has unintended consequences china is not to be trusted or believed and not relied on in the future return manufacturing to the usa and europe

Sounds like a bio-weapon to me.

Influenza is a very special case where vaccines are involved.

For most diseases, antibody mediated immunity decreases over time. This is the case with influenza, as well. In addition, influenza mutates a lot through various mechanisms, so that even if you are immune to a particular strain of H1N1, you are not necessarily completely immune to the strain that circulates the following season. While there is, as you noted, some cross-immunity, that does not substitute for a fresh dose of (hopefully more targeted) immunity conferred by vaccine.

Would you mind answering a question? In your practice, have you ever recommended a pregnant woman receive the annual flu vaccine? If you have, would you mind telling me the vaccine brand that would be used?

How could you possibly know this if no one is tested before they are given the vaccine? Isn't it just an assumption based incorrectly on vaccine-acquired immunity which indeed is much shorter lived. I believe I read somewhere on the CDC website that the maximum length of immunity from the vaccine is 126 days.

I ask again, why would you not first find out if someone retains their immunity before shooting them up with a quadrivalent vaccine cocktail?

Are you of the belief that vaccine-acquired immunity is superior to naturally acquired immunity?

Oh my God! That's all we need! We might as well just give our whole country to these communist bastards!! OUR GOVERNMENT HAS STABBED AMERICANS BACKS for decades all because of $$$$greed!! That includes Feinstein, McConnell boxtic pelosi and the rest of the greed bastards that went into congress penniless and will leave worth millions and millions of dollars!! Seems china owns just about everything that's needed for survival in this nation including the meat packing corporations! This is really getting to be extremely frightful! They have us over a barrel and they know it! They're winning this war silently without firing a freaking shot! we are at the cusp of losing our beloved country ...😢

Common colds can come from both rhinoviruses (which the Chinese Frankenvirus amazingly seems to start out as in most symptomatic patients) and the milder coronaviruses (which tend to occupy the lower respiratory tract). This POS pretends to be a rhinovirus, and should the body’s response not be robust enough, then goes south to the lungs, heart, kidneys, etc. The Chicomms really created a monster here, albeit one that won’t have a high a death rate, in the end, as we feared.

It doesn't matter if the immunity is from a vaccine or from the disease. Since most influenza vaccines are made from virus particles, the body sees exactly the same viral proteins as it would if infected by the virus.

I know about the decay of immunity over time, because this is a very heavily researched subject. Most diseases do not cause permanent immunity.

I ask again, why would you not first find out if someone retains their immunity before shooting them up with a quadrivalent vaccine cocktail?

Why would I subject someone to a painful and invasive blood test, especially when the justification is so thin? I *know* they have some influenza antibodies, that isn't the issue. Whether they have antibodies that will protect them from the circulating strains is something different, and not that straightforward to test. I think that developing such a test for every single circulating strain of influenza would be expensive, and not quite as precise as people might believe.

Personally, I do not inject anyone with anything. I am a PhD, not an MD, and have no direct involvement in patient care. I am, however, a medical researcher, and vaccines (influenza, especially) are one of my subspecialties. Influenza vaccine technology is decades old, with the exception of the newer cell-based vaccines. It has a long and proven track record. I'd rather get a little injection that have someone pierce my arm with a huge needle to draw out copious quantities of blood for a questionable test of whether I'm immune to the circulating strains.
