! Moderator Note This seems like a slightly repacked topic posted elsewhere already. The same issues also exist in this one, so please consider the previous comment before goin on yet another rant:

It is one of the weird arguments I started to keep hearing recently, and I think it is based on a misconception of what a vaccine does. Fundamentally, it is a stimulant of the immune system, helping us to fight off an incoming infection. It is not an one or all situation, but mostly a vaccine is considered effective if the overall outcome is improved compared to an unvaccinated cohort. I think part of it is how immune is being used, and the idea that being resistant against infections should equate not being able to be infected. It does not help that the language is a bit loose in that regard. Herd immunity, for example refers to stopping spread, but the situation can also dependent on non-immune system related measures. I.e. by reducing the effective reproduction number of the disease (e.g. by reducing contact time between individuals).

! Moderator Note I see no biological science in that OP. The topic is moved to speculations and OP is requested to provide evidence for their assertions. If none are delivered and this post remains a blog style, it will be locked.

Think about what PDT is used for and where the drug would be delivered to. Specifically think about how the drug is delivered to its target and where low water solubility can cause problems.

Also mechanistically it does not make sense. Vaccines provide robust immune responses including neutralizing antibody formation (https://doi.org/10.1038/s41586-021-03653-6). And the mortality numbers have been adjusted in many reports and studies by age and comorbidity, yielding uniformly protective results (though with a drop over time, especially in the elderly).

Which means they allow vaccinated individuals to mount an effective immune response, which in turn is the function of a vaccine...?

Or you can ask for a name to be appended to the approved list. It does need to follow certain rules, though (edit: in hindsight not sure whether a name was actually approved or just a nickname).

Do you have a reference for this? I am a bit surprised as most calculations on mutation rates at the replication level are much lower for SARS-CoV-2. Or are you referring to the likelihood of new variants. That is dependent on the number of active infections but also the overall fitness landscape (e.g. effects of purifying selection).

A recent study indicates that omicron seems to have increased rates of hospitalization among unvaccinated children and adolescents. The authors have adjusted for incidental COVID-19 cases and found:

! Moderator Note The answer is No. Also, nothing in the post seems logical, and the reasons for high death rates in the US are well documented and include: - dismantling of pandemic response forces and plans - downplaying the disease by politicians and especially the former administration - crippling CDC and other health professionals and undermining their message by the administration - as a result, anti-pandemic responses were fractured and often counterproductive (catastrophic PPE distribution, is but one of the many examples) - sowing vaccine hesitancy - lack of solidarity and trust in science We do not need a bioweapon, if we have facebook. Since this appears to be an attempt to promote conspiracy rather than a discussion, the thread is locked pending review.

Also, they failed to provide any evidence that there was more safety data out there before any of those have been approved. If you register a trial you propose a time point when you expect to hit an endpoint which can be used to demonstrate efficacy (PhaseIII). In case of vaccines they can be based on infection events or disease manifestation. Once the endpoints are met, they are submitted to the drug agencies for review, where requests for additional data could be required. Due to a little, barely noticeable global pandemic, these endpoints were reached really fast and no surrogates were required. But this this point has been made repeatedly and are ignored or met with willful misunderstanding of the process. So let's ask instead: what endpoints did other approved vaccines met that the COVID-19 vaccines didn't? I would like to see evidence that individuals in any of the previous vaccine trials were monitored for longer than three months for side-effects, before wasting any more time on this. Notice that you again fail to understand how trial endpoints work. Or that in Phase IV (i.e. after release) effectiveness information is continued to be collected which then allows regular approval (which also happened). See, if one does not make an effort to understand the process, it is easy to get baffled. But it becomes an issue if instead of reading up and trying to understand the process, one then creates a dangerous narrative that is based on said failure to understand. In most other circumstances it would be easy to dismiss, but in the age of social media, weaponized ignorance is unnecessarily killing folks. That, together with a distinct lack of solidarity shows how difficult it is for us to face a common challenge.

I suggest that you take a look at the syllabus for your course. Typically there will be textbook recommendations. If the recommended books are not online/open source, you might be able to get them from your library. More often than not, lectures are structured around a couple of textbooks so you can easily read up on the topics. In fact, the original intention of lectures was that students first read the textbooks and then use the lectures to deepen/apply the knowledge and to get guidance into context.

Also folks under cancer treatment are extremely vulnerable to infectious diseases such as COVID-19. In the US COVID-19 alone is only behind heart disease and cancer as the leading disease. The mere fact that there are folks still trying to minimize its impact at this point truly and fully establishes how f---ed we are. Especially when the next disease (or a more deadly variant) comes up. Also, it is annoying the those pro-virus folks newest (or at least one of the newest) talking point is how somehow the COVID-19 deaths are all overcounted, whereas epidemiologists and other folks who actually calculate these things indicate that they are likely to be vastly undercounted. To make it perfectly clear, folks dying with rather than of COVID-19 is for the most part a myth, driven seemingly by the rise of Omicron in vaccinated populations where there was a substantial number of incidental COVID-19 hospitalizations. However, comparing the numbers coded with COVID-19 as cause of death, vs just presence of COVID-19, (e.g. looking the ONS data, freely available and with clear definitions of what they consider "involving COVID-19" vs "due to COVID-19" in the mortality analysis) it still appears that whenever COVID-19 appears, it is still the underlying cause of deaths in over 80% of all cases. Looking at the data, one can also see interesting patterns. Early in the pandemic, the highest proportion of deaths in which COVID-19 was involved but also the cause of deaths was very high (ca. 95%) and dropped when the cases were low and vaccinations started to increase. However, whenever a wave hit, the values go up to 80% again. I.e. if the disease is wide-spread it will more likely to hit vulnerable (including unvaccinated) folks, exactly as we would expect. But then, it is abundantly clear that this is not about facts at all, but rather to try to find narratives to justify one's worldview, even if it kills us.

Basically, if the test was not applied correctly, you do not know whether you got COVID-19 or whether you are still contagious. The rough timeframe of being contagious was about 1-2 days before you got symptoms and for roughly 10 days after. But a test would be much better to ascertain that. Wear a tight mask, see if you can get tested again (either rapid or PCR) and talk to your MD.

Did you use an appropriate gel percentage to see your fragments? Did the BamHI digest also show a smear? Was the undigested product smear-free? Was your estimate of the amount of DNA accurate? You could try to make prolonged digests (assuming no star activity) just to make sure. Finally if it is important, it might be worthwhile to submit your product for Sanger sequencing. Prices are so low now, it tends to be cheaper than the work time and material required to do all the trouble shooting and it gives at minimum confirmation that the ends are correct.

It is simple, really. If you want your group to rally around your cause, the easiest approach is to create a foe.

It should be noted that the UK SC has also limited power as it cannot overturn primary legislation by Parliament. Inherently, their appointment therefore becomes less political as it cannot be used to change legislative agendas (from what I understand at least).

Another study on veteran's data in the US indicated that COVID-19 is associated with an increased long-term risk of cardiovascular diseases. For all types of cardiovascular cases the excess burden (i.e. additional cases per 1,000 persons) after a year was 45, with heart failure and atrial fibrillation being the most common issues.

It is slightly off-topic but I think it is worthwhile highlighting that terms like immunity, tolerance and resistance are often used in slightly different ways depending on context. In "classic" microbiology, which includes non-medical contexts we often use the terms tolerance to define a host-pathogen interaction which does not negatively affect host health but is also not being detrimental to pathogen fitness. Resistance on the other hand typically refers to direct limitation of the pathogen burden (and can include passive and active elimination of it). Unfortunately this is about the most consistent definitions you can find in literature and after that things get muddied up, depending on the sub-discipline. Immunity is then generally often referred to as a resistance mechanism, which can include our immune system, but sometimes also refers to other mechanisms which are employed to defend against parasitic interactions (it can be used in the context of bacterial mechanisms to fend off bacteriophages, for example). But unfortunately when it moves into the medical area, language can get a bit vague as the focus there is less on the direct interactions between host and pathogen (and underlying mechanisms) but is typically (and perhaps unsurprisingly) based on health outcome, such as disease development. Moreover, typically there is little consideration with regard of infection in the process. Infections are mostly considered in the context of host range but rarely (to my knowledge at least) extends to individuals. Individuals who get infected, but never develop symptoms would under the classic definition considered to be tolerant, but sometimes are also called immune, for example. But then, this is also used to describe a situation when an individual has the ability to clear the pathogen before disease manifests (which would be a resistance mechanisms). It also does not help that those terms are sometimes are not used consistently within a field, in part because mechanisms often overlap or are linked. That being said, natural immunity rarely is used (at least from what I have seen) to describe a situation where an individual cannot be infected by whatever reasons. Rather it does refer to immunity (in terms of resistance) due to exposure to a pathogen and is contrasted to vaccine-induced immunity. Neither of them meaning that one cannot get infected, but rather describing a situation where resistance is enhanced, if that makes sense. Time makes it even more complicated, as at this point we would need to look at the time dependent response of the immune system (where fast responses wane but slower long term responses have to take over) but also new variants play a role.

So is there data out there that would suggest either? Because most reports I can find on Lionfish does indicate that there are efforts underway to control them and I am unable to find reports indicating that they are mostly non-disruptive. Sure, it is possible that the worries were overblown, but before declaring it a myth, I would like to see some evidence. And if I scan lit on the Southern Caribbean I see a number of efforts to cull them (https://www.forbes.com/sites/daphneewingchow/2022/01/31/the-caribbean-is-taking-a-bite-out-of-its-invasive-lionfish-problem/?sh=648af9cb5e8f) There several papers that try to investigate the impact and cost of lionfish management, e.g. DOI:10.1007/s00227-015-2745-2 and a number of agencies, including NOAA seems to spend quite a bit of efforts on controlling this species, too: https://www.fisheries.noaa.gov/southeast/ecosystems/impacts-invasive-lionfish So at least that makes it strange that apparently either no one picked up on the fact that they are harmless (and spending a lot of money on it) or at least I cannot find reports on that.

If we had concentrated HCl or even HF in our bodies, we would be pretty much dead. . Concentrated HCL has a molarity of ca. 12M whereas the concentration in our stomach is ~0.15M. Also, I am pretty sure that even in concentrated HCl it will take quite a bit longer than a few hours to dissolve bone.

I wonder whether that is really a myth. Or conversely, are there studies that indicate that lionfish are non-disruptive for the ecosystems they got in? A quick google seems to indicate a fair number of studies where they seem to indicate significant damages. That being said, these were mostly a few years old already and it would be interesting to see what the current state of science is on that matter. One of the newer ones for example: https://doi.org/10.1080/03632415.2017.1340273

I mean, what else would become feces but what we ingest? Note that food does not liquefy in your stomach. It gets partially digested and mixed up, but it is mostly a pulpy mess. As this liquid pulp travels through our intestines, excess liquid gets re-absorbed by our intestines.

Hey, you know, just saying, but we can help with excess funding...

Actually folks knew for years that we need to put more money into vaccines to speed up development. Folks were just not that interested until recently.
