The last few weeks have been a bit like the first dates with 3 other vaccines opposed to covid-19 coronavirus, they were first positive appointments, but first dates.
Since 9 November, 3 vaccine manufacturers, Pfizer, followed by Moderna and then AstraZeneca, have had some initial effects from their Phase 3 clinical trials. And the numbers of the units look good. Pfizer reported a vaccine efficacy of more than 90% for its mRNA-based vaccine candidate BNT162b2, a modern vaccine efficacy of 94. 5% for its mRNA-1273 and an AstraZeneca vaccine efficacy of up to 90% for its AZD1222Array
Ninety consistent with penny is an impressive number. However, before saying ‘I got 90%’, keep in mind that those are still very initial results. Don’t start dreaming about starting a new life with vaccines yet. By contrast, the following 8 limitations for all of these initial results:
1. They can still confuse what you are looking for.
Remember how the 3 brands came here combined and performed their tests. I have already described the design of the AstraZeneca Phase 3 clinical trial for Forbes. Each trial consisted of recruiting a large number of volunteers and giving one organization of participants examined the vaccine and another. organization a placebo, which is necessarily a fake vaccine. Participants don’t know who gets what. The trial will then involve following any of the equipment for months and testing them periodically for Covid-19 coronavirus infections over time, trial researchers can determine the percentage of each organization that eventually develops Covid-19 coronavirus infections. then use the following formula to calculate the effectiveness of the vaccine in the trial:
Vaccine effectiveness – (Percentage of un vaccinated people receiving Covid-19 – Percentage of vaccinated people receiving Covid-19) / Percentage of un vaccinated people receiving Covid-19
Therefore, if 10% of the un vaccinated organization and 1% of the vaccinated organization obtained Covid-19, the effectiveness of the calculated vaccine would be 10% minus 1%, or 9%, divided by 10%, which to 90 The vaccine would also be effective at 90% if 0. 1% of the un vaccinated organization and 0. 01% of the vaccinated organization ended up receiving Covid-19.
The challenge, of course, is not that all test participants have the same threat of being inflamed with the virus in the first position with or without the vaccine. Your threat of getting inflamed depends to a large extent on the precautions you and those around you in for example, opting for fights with others in Costco without dressing up in a face mask can increase your threat, so being on a network where other people think and act like covid-19 coronavirus is not a problem.
This is one of the main reasons why clinical studies, such as existing clinical trials of the Covid-19 coronavirus vaccine, will have to come with a large number of participants examined, tens of thousands in vaccine trials. The studies try to match the possible differences between those who get the vaccine and those who get the placebo. Suppose you’re trying if other people prefer bacon on your breakfast plate over the full body. Selecting only 20 other people for the exam would threaten to opt for too many from the “I Love Bacon in My Body” crowd list. The enrollment of thousands of others in the study would be more representative of the percentage of the population that confuses meat products with clothing.
Similarly, having more test participants will make it more likely that the average vaccine and placebo teams will have the same threat of exposure to the virus. This is also why you should be suspicious of the initial effects that spread only a few months of testing and not all expected participants.
2. Duration of coverage issues.
Speaking of several months. Imagine if someone told you, “There’s a 90% chance they’ll vibrate your overall in the first few months. After that, the dates will be terrible, would that inspire you to have a date for now?Maybe, depending on your current boredom and what you need to see on TV. But that doesn’t bode well for a strong relationship and a sense of long-term security.
Similarly, being protected through a vaccine for just a few months is very different from being protected for six months to a year or more. Although Pfizer, Moderna and AstraZeneca Covid-19 vaccines would possibly eventually be offering coverage for more than a few months, Judy Stone discussed for Forbes this and other disorders with Pfizer’s announcement, they have not continued long enough to know how long vaccines may be offering coverage. In fact, the trials might not even have lasted long enough for everyone to be exposed to the virus. .
3. The effects come from summer and early autumn.
As Olivia Newton John and John Travolta told us in the song “Summer Nights” from the film Grease, things don’t stay the same after the end of summer. The song doesn’t say, “It’s colder and less rainy and that’s when it’s over. “But it would be a reminder that knowledge of clinical trials to date comes largely from summer and, in all likelihood, from the beginning of autumn. As I explained earlier for Forbes, cases of Covid-19 coronavirus have more next month as temperatures and relative humidity have decreased. Therefore, the threat of infection may be much higher today than in the first few months of trials. The question then is whether the effectiveness of the vaccine will be minimized as the threat of infection increases.
4. It is not clear how the efficacy of the vaccine might vary from one user to another.
What if a clinical trial had decided that a specific pair of underwear is suitable for people?Your first question might be: why did they do such a clinical trial?Their moment and the third question may be: who did they come to?in the clinical trial and how did the effects vary from one user to another?Similarly, the effectiveness of the vaccine and in the end the effectiveness of the vaccine (which is the effectiveness of the vaccine in the genuine world) can vary significantly depending on age, size, physiology, immune formula and other user factors. Press releases did not break down the effects according to these other characteristics.
5. Tests may vary.
Trying the Covid-19 coronavirus is not like figuring out if there is a hedgehog on your head, it is usually quite simple to know if there is a hedgehog on your head, unless, of course, you are dressed in a beret on the hedgehog. Even in this case, one more step, “excuse me, you can also remove your beret to see if you have a hedgehog on your head,” will simplify the diagnosis. The same is not true for Covid-19 coronavirus. For popular nasopharynx and oropharynx tests, to unload a suitable sample, you must insert a cotton swab into your nose and back of your throat. This is not easy to do, so the quality of samples Other types of tests, such as pin tests, would possibly not be as accurate as nasopharyngeal and oropharyngeal tests. Therefore, knowing more exactly how the tests were conducted, what were the express effects and what diversifications of the protocol happened will help to better compare the vaccine efficacy effects of e.
6. What are the results?
Telling him it’s positive for covid-19 coronavirus is not like telling him there’s a hedgehog in his head in more tactics than one, of course, the hedgehog can take other poses and do other things, such as hedgehog. possibly read a very small copy of The Power of Positive Thinking or twerking. In any case, those odds might not radically replace what you want to do next: the hedgehog in your head.
On the other hand, there is much more variability in what can happen when you’re inflamed with Coronavirus 2 of Severe Acute Respiratory Syndrome. Or things can get worse, much worse. In addition, disorders can persist far beyond infection. The question remains, then, how effective (and effective) is the vaccine to prevent the other types and severity of Covid-19 coronavirus infections?Are vaccines effective in preventing results?
7. The clinical trial setting is the real world.
A clinical trial is like a truth show. While it is meant to imitate the truth, it is not the same as the truth. It’s not a smart concept to do a wedding-themed photo shoot on the first date like they did at The Bachelor. Truth demonstrations and clinical trials read conscientiously about others before they enroll in a clinical trial. A user who enrolls in a Clinical Trial of the Covid-19 vaccine may not be the typical or average user in the United States. for example, you are more likely to be more informed about the virus and are more likely to stick to precautions against Covid-19 coronavirus.
In addition, truth television and clinical trials demonstrate the Hawthorne effect: others are more likely to replace their behavior when they look at them. platinum,” as Corinne Olympios did in The Bachelor. On the other hand, those involved in a clinical vaccine trial would possibly be more careful in preventing Covid-19 coronavirus infections because they know they are being followed.
In addition, things can be much less difficult on real TELEVISION and in clinical trials compared to real life, as many more people are paying attention and listening. Hot tubs don’t magically look like they do at The Bachelor. will come from a hot tub is to break the wind in a bathtub. Possibly a clinical trial would be offered that would possibly not exist for everyone in real life. For example, establishing a clinical trial can ensure that vaccines are well stored and that participants have a tendency to get the right doses at the right time (well, the maximum time, at least). All of this is why it is called “vaccine efficacy” when measured in a clinical trial and “vaccine efficacy” when measured in the genuine world in general, the effectiveness of the vaccine is less than the effectiveness of the vaccine for a given vaccine.
In addition, the effectiveness of the vaccine will depend at the end on the number of people who are vaccinated; the more people are vaccinated, the less the virus can spread and the more effective the vaccine becomes. The opposite is true, too.
8. Knowledge and effects have been peer reviewed throughout the clinical community.
Keep in mind that to date, vaccine effectiveness figures come from press releases, not peer-reviewed publications in renowned clinical journals. Almost anyone can factor a press release. In theory, you can simply factor out a press release stating that you had a delicious dessert brownie or that they were hot dogs to create a reproduction of a Thanksgiving turkey. Publishing the effects in the form of an original peer-reviewed study paper in a renowned clinical journal is another story. Most clinical journals don’t. have a “Hot Dog Things” segment and have a much higher bar that will have to be reputable for publication.
Press releases also tend to focus mainly on positive news. A company is less likely to factor a press release that says “yes, our product is weak” or “Oh my God, we’ve missed it. “Of course, positive press releases can help a company get more help for its product. That is why it is so vital that independent scientists examine the effects in a transparent way to find out whether the conclusions actually correspond to the knowledge and strategies used.
Again, while the effects of Pfizer, Moderna and AstraZeneca are encouraging, don’t expect a global vaccine even after the vaccine. As Guns N’ Roses told us, all we want is a little patience. the first date of a series of dates. Much remains to be learned about the prospective effectiveness of the vaccine, its duration of coverage and its possible appearance effects. For now, it turns out that some dates at the moment are in order.
