変異型コロナをなめたらアカンーより高い感染率、再感染　ワクチンが効かない、ないし効かない可能性 　治療も効きにくい、と。

Another 2 cases of British coronavirus variant found in Mass. By Martin Finucane Globe Staff,Updated February 5, 2021, 11:32 a.m. 
 The British variant has an infection rate 25 percent to 40 percent higher than that of other forms of the coronavirus, Public Health England has estimated. Adding to the concern: Some preliminary evidence suggests the variant may also may be more deadly.

  South Africa coronavirus variant: What is the risk?
Is it more dangerous? There is no evidence that the South Africa variant causes more serious illness for the vast majority of people who become infected. As with the original version, the risk is highest for people who are elderly or have significant underlying health conditions. But there are concerns it can spread more readily and vaccines may not work quite as well against it.

 A new Covid variant has been discovered in Brazil — here’s what we know so far

“We had a look at this particular mutation, as opposed to many other thousands, very carefully, saw there may be an issue, not so much that the vaccine won’t work, in fact scientists think it will work, but just the fact it is more spreadable,” Shapps said, according to Reuters.

New variants raise worry about COVID-19 virus reinfections

By MARILYNN MARCHIONEyesterday

Reinfections pose a public health concern, not just a personal one. Even in cases where reinfection causes no symptoms or just mild ones, people might still spread the virus. That’s why health officials are urging vaccination as a longer-term solution and encouraging people to wear masks, keep physical distance and wash their hands frequently.


“It’s an incentive to do what we have been saying all along: to vaccinate as many people as we can and to do so as quickly as we can,” said Dr. Anthony Fauci, the U.S. government’s top infectious disease expert.


“My looking at the data suggests ... and I want to underline suggests ... the protection induced by a vaccine may even be a little better” than natural infection, Fauci said.


 Scientists discovered a new version of the virus that’s more contagious and less susceptible to certain treatments. It now causes more than 90% of new cases in South Africa and has spread to 40 countries including the United States.


Madhi led a study testing Novavax’s vaccine and found it less effective against the new variant. The study also revealed that infections with the new variant were just as common among people who had COVID-19 as those who had not.


“What this basically tells us, unfortunately, is that past infection with early variants of the virus in South Africa does not protect” against the new one, he said.


In Brazil, a spike in hospitalizations in Manaus in January caused similar worry and revealed a new variant that’s also more contagious and less vulnerable to some treatments.


“Reinfection could be one of the drivers of these cases,” said Dr. Ester Sabino of the University of Sao Paulo. She wrote an article in the journal Lancet on possible explanations. “We have not yet been able to define how frequently this is happening,” she said.
