As natural mutations increase the number of infectious and potentially lethal virus strains, COVID-19 is now pandemic worldwide and threatens to turn back on the latest advances in disease resistance due to Vaccination
Last week, Houston became the first big city in America to report the existence of five strains concerned by medical experts – the Californian breed known as B.1.427 / B.1.429, a strain of New York is classified as B.1.526, Brazilian species P.1, a species known as B.1.351, believed to have originated in South Africa and the UK mutation B.1.1.7, which the Center for Control. And prophylaxis are predicted to become the dominant strain in the United States by the end of the month.
Each new variant comes with some worrisome new features. For example, P.1has been found to make re-infection easier, while new studies show that B.1.1.7 extends the infection duration far. Than the original species
With so many questions raised by the growing number of mutations, Yahoo News is asking Dr. Kvita Patel, medical expert (The following interview has been edited for clarity.)
Yahoo News: How Should Americans Be Worried About The Corona Strains Is Spreading Now?
Dr. Kavita Patel: I think people should worry. There is a large population – the vast majority of the population who are not vaccinated. They are very worrisome, as they are the primary target of these viruses, whose species are likely to reproduce.
Remember that the target of the virus is not to kill people. But really, it just keeps living, and the only way to do it is by infecting people. Unvaccinated people should be incredibly worried, which is why I’m so worried about variables, as I am now looking at 12 states and sizeable state counts including Texas and Florida raising. The level of demand, mask or leave it on Per person or business That’s a group that should be very worried.
Even people who are vaccinated should be concerned because of these things. [vaccine] Most of the ongoing experiments did not happen when we were experienced with these variables. Therefore, we are all happy that vaccines can perform to a certain extent compared to different strains. But we are not sure how long it will last, whether we need sponsors or not. All manufacturers are already talking about a booster vaccine, so getting a vaccine is great for alleviating your mental symptoms. But I’ll be honest with you, I’m still worried when I leave the house, mostly because These variables
Currently, only a small percentage of the population of more than 16 percent of the United States receive at least one dose of the COVID-19 vaccine. Is there a degree that mutations will not pose a huge threat?
We know that in conventional virology or infectious diseases 50 percent or more, the more people are vaccinated. [the more] Reduce the rate of infection R naught or Rt, which is [the measure of] If you get infected, how many people will you get? That number is already decreasing and it will continue to decline, it will never reach zero. But it is quite close. So if you are infected, basically you are not likely to infect others when we have a certain level of immunity.
Everyone was asking, ‘Is the herd immune?’ But not a power switch, so the higher we go 50 percent, the lower the chance of infection. That’s good news We’re getting closer and closer, but we’re not going to be there any more – it’ll take weeks, if not months, before we get there.
One of the fears of epidemiologists is that the virus could mutate, making existing vaccines useless. If so, will we start over from scratch?
It’s hard to make it totally useless. It will have to be drastically changed. Keep in mind that the vaccine itself does not target just one component on a protein that blocks or regenerates proteins in any way. Vaccines provide what we call a polyclonal antibody response, which means that all three vaccines, in fact, all around the world, all stimulate the immune system’s response to the different parts of the protein blocking it.
When Pfizer said their vaccine developed antibodies against different strains. But to a lesser extent it means that it works fine with variables. But it’s only because the evolving response is very good, not 100 percent, not 95 percent, but probably about 80 percent – and that’s the number I’m building … what is it? [variants] Yes, it is – more likely – for the person who is vaccinated, we are very confident that the person will not die or develop a serious disease. But there is a high probability that some of these variants could exacerbate some vaccinated people.
The flu is mutated each year, a new vaccine is required. Is this what we can expect from the new yearly COVID-19 vaccine?
We’re definitely headed for seasonal vaccines. Whether every year, twice a year, every two years, the time is uncertain.
Is it possible for the virus to mutate so quickly that it requires more than one vaccination per year?
The short answer is: Yes, we know everyone is working with boosters. We are familiar with vaccine terminology. We use a booster in shingles, we use a booster in tetanus. We use boosters in other vaccine settings, so it’s not unusual to see boosters. What’s interesting is that if we need a booster every six months after we are vaccinated, not because the immune system goes away after six months. But in dealing with that variable, many mutations accumulate.
One of the reasons I’m not as worried as some people are talking about the fourth power surge, and it’s devastating, is that tons of non-mutated viruses. If you go back and look at how many people are infected, we’re now talking about these really threatening mutations, meaning we’ve gone a year without a wave after mutations and variables.
That’s why we think the B.1.1.7 variant, a series of mutations, will be the dominant species in the United States by the end of this month, and then it might take a while before we see the species. Or other variables can be overtaken if you think so, that means the time could be yearly for a booster vaccine or a completely different type of vaccine.
But it surprises me that the virus is doing a great job of mutating. Even when the virus spreads from China to Europe to the United States, when it comes to New York, isn’t it a different species, is it?
We are using a very different vocabulary. Tons of mutated viruses The variable will not become a stress until it is medically relevant to it. [the virus] Has mutated from the right travel But it wasn’t mutated in a way that caused significant clinical effects until recently, and that’s the difference. So we have European species, we have Wuhan species. But the clinical nature of the virus has never changed, and now the differences and the reasons we think B.1.1.7, B.1.351, P.1 cause more concern. [is] Because they can be more transmitted and can be more life threatening. But look how long it takes.
You mentioned earlier that you are not as worried as everyone else that we are going to have a fourth virus on us –
Oh, we’re going to have a fourth wave. But I think it will explode. I’ve heard some people say, ‘This is the Eye of the Hurricane, this is Calm, the cases are about to subside, and they’ll explode.
I think the cases will slow down and gradually go up. I don’t think it’s going to be this big. And I think that’s because I think we’ll be able to get 2 million vaccines a day, maybe more. We’ve already got vaccinated, the percentage who got the first vaccination – among those populations most likely to die. Not all But of course there will be a death count and hopefully the cases will be counted as well.
But that implies that the variables will not arise, which will actually evade the antibodies.
Yeah, that’s why I’m still worried.
We are still at 65,000 per day in the United States, do we need to significantly reduce that number in order to start dealing with this strain or increase the vaccination sufficiently?
Oh yes. Even with vaccines, we need to cut those numbers by using masks and mitigating measures. The old-fashioned good things we did in the first try to reduce the numbers, because we know that even 100 million shots tomorrow, we know two-thirds of those things still need a second drug, and we. Know your best immunity, even if you are immune after all the first vaccinations. But it still takes several weeks to develop.
I have an incredibly large number of patients with COVID positive and are puzzled by what happened: ‘Doctor, I had my first vaccination last week.’ Broad-spectrum vaccines But it will take several weeks to see if we can reach the immune level. I am very worried, even for people who are vaccinated. But the burden of patients – the rate of community infection is high, especially in some states where they lift all restrictions.
If our strategy is based on vaccines, I think we can look forward to the future of routine vaccination.
By the time they [boosters] This is allowed through a process to make sure it is safe, are there any other sets of variables we have to deal with? These are all questions that arise when it comes to booster, vaccine, and which vaccine you are taking today, will it be a vaccine that you have to take three months from now, again, six months from now, or every year? All life.
