Get a booster now if you are immune suppressed, unless you've just been vaccinated. Everyone else, currently 8 months. This will likely change to 6 soon, possibly 5 months for Pfizer.

Second sentence in the article. I have Good News/Bad News for you. Covid already does this with an asymptomatic period and not killing the infected for several weeks. It's why there is no selection pressure driving it to become more mild. The vaccine is unlikely to produce any response you wouldn't already see naturally. Having a shitload of infected people causes the same problem. Delta and Gamma both evolved in populations with zero vaccinated people and many previously infected ones.

4-6 months for Pfizer, longer for Moderna, but we don't know how much. We'd be fine against OG Covid, or Alpha, but Delta spreads faster and infects faster.

Not a DR disclaimer. Official advice is take the same as your original. NIH/NIAID currently has a study looking at mixing and matching vaccines. Until those results come back, the CDC is going to tell you to take the same one. That said, they'll also say you can mix if that's the only option, because the data seems fine and other Western countries did it with no issue. I advised my immune compromised relative, who asked, to switch and take Moderna. Reasoning was they are also exposed to kids that go to an unmasked school and definitely need the stronger, longer lasting immune response. They were exhausted for 36 hours and then back to complete normal.

The Salet Days.

It's an existential threat, but most won't view it that way. Their normalcy bias prevents it. They are surrounded by people that make decisions frequently based on data and logic. They don't understand that a huge chunk of this country makes decisions predominantly on emotion. It's not about facts, it's about feels. That's not a matchup that favors the Scientific Method.

JFC, this isn't difficult unless you are intentionally trying to misunderstand it. The current evidence says ivermectin is an ineffective treatment for Covid, but a great way to get rid of skin and intestinal parasites. There is no evidence to show that it works on Covid, so it is currently a false treatment and such claims about it are pseudoscience. That may change when the current clinical trials are finished, but that is the future, not the present. In the meantime, the fraudulent profiteers promoting ivermectin are making money hand over fist, while victims of these charlatans are chugging sheep dip, or slamming peanut butter and horse paste sandwiches, then clogging up our poison controls and ICUs.

SEC, it just infects...more.

Look out JFK Jr.

Matches the reports of antibodies they were finding. There are a fair number of animal reservoirs for covid and it's pretty wide spread across the mammalian family tree. Primates, weasels, dogs, cats and deer is a pretty good smattering. It's likely a safe assumption that at least some other mammals can serve as a reservoir as well.

The right wing declared war on science long ago. We got our asses kicked, before most of us realized we were in a fight. Now they've declared war on reality. We are once again, getting our asses kicked. Disinformation is killing people all across the country, but most still don't realize it's an existential fight between facts and alternative facts. Reality isn't political. Science isn't political. Facts are facts and alternative facts are lies, or at best, distortions. If we keep catering to these motherfuckers, we will be in an ever increasing dystopian nightmare.

The well is being poisoned by the same profiteers that politicized masks, vaccines and promoted HCQ well after it was debunked as an effective Covid cure. Ivermectin has been thoroughly discussed on here over the last 18 months. At one point, many of us were optimistic that it might help Covid, but the bulk of the evidence says it does not. It is also not being suppressed. An ivermectin clinical trial is currently being conducted to determine if it is safe and effective in different dosages. If the trial shows it works, doctors will prescribe it at that dosage. That's how science and medicine work and why it's called "Evidence Based Medicine". This trial likely would have started and concluded sooner if the same dipshits screaming about ivermectin had shut the fuck up about HCQ. An ENORMOUS amount of medical capital and human trial volunteers were wasted and the same dipshits now screaming about ivermectin are responsible. Without all the time, money and human volunteers these fuckers wasted, we could have also gotten further on drugs with actual potential, such as fluvoxamine.

That's what I would do if I was exposed to higher risk scenarios, or patients, as well. The non-valved aren't that bad.

The surgical are all too small to fully cover them and wind up being pulled really tight against the valve. The majority of the air winds up being forced through the mask, rather than diverting out the sides, which is one of the big problems with most cloth and surgical masks. I'm sure it's not N95 level protection on the exhale, but it's pretty good. It's also a lot more comfortable, so I wear it consistently. Mileage may vary for smaller faces though.

I rock that with a paper surgical over it.

I got called up there a number of years ago when they were scanning the Archaeopteryx feather. https://www-ssrl.slac.stanford.edu/content/sites/default/files/documents/science-highlights/pdf/archaeopteryx-201005.pdf It felt like I was in some Bond villain's underground lab the whole time. It's a huge loop of stuff that looks like this the entire way around it. Crazy ass machinery and electronics everywhere.

I wear two every time. The N95 protects me, while the surgical mask filters and breaks up the valve outflow to protect others. It still vents really well and is much more comfortable to wear, while keeping the N95 underneath "clean" for the next use.

JFC, cloth mask is better than no mask. N95's are better than cloth. I wear a valved N95 with a surgical mask over it and have recommended it repeatedly on here. A lot of lives would have been saved if Trump had used the Defense Production Act to produce N95 masks for everyone and distributed them. Biden should have done the same thing. That said, primarily aerosol spread doesn't mean it doesn't spread via droplets as well. That's Texags level logic. Wear the best mask you have access to.

Even if Delta is no more severe, it is clearly MUCH more contagious and many more kids are going to contract and spread it. Pediatric hospitalizations are already up sharply, before you add any of this unmasked in school stupidity. If you look at the recent hospitalization trends from the CDC, it's clear as day that Delta is very different than OG, or previous variants for kids.

Unfortunately, doesn't look like they calculated absolute breakthrough/re-infection rates and I'd revise my earlier post to reflect that if I could. They appear to have collected the data as visits, rather than individual patients. I don't know if they have individual patient data, but they didn't report it directly, Table S2 was as close as they got, but this is for visits, not individual patients.

Oxford pre-print just came out comparing vaccine effectiveness for Pfizer and AstraZeneca compared with unvaccinated, previously infected in the UK. The data runs through August 1, so it gets both Alpha and Delta. 2-dose Pfizer provides superior protection to a recovered natural infection for either Alpha, or Delta. https://www.ndm.ox.ac.uk/files/coronavirus/covid-19-infection-survey/finalfinalcombinedve20210816.pdf

Fuck off Fozzz. Your entire schtick as a poster is willfully obtuse. I've already posted data showing variants cause re-infection in previously infected people countless times over the past two months of dealing with you and GRHorn's disingenuous bullshit. There is no herd immunity without a robust vaccination regime and boosters. There was debate about this 2 months ago, there is no debate about it now.

cross posting this Not a doctor disclaimer... There are no studies using mRNA vaccines to boost J&J. There is data for Pfizer as a booster for AstraZeneca. It is safe and highly effective. Some people mixed mRNA for their initial vaccinations. Several western countries did as well. All indications are that it was safe and effective, but no studies were done. The CDC is just starting a study to look at mixing and matching different vaccines and booster shots. Insert my obligatory complaint that the CDC has been way too slow at everything. Until that data comes in, the CDC/FDA and most doctors are going to be cautious. The limited data available says it is safe and effective, but they aren't going to recommend it until they have lots of data to stand upon.

Until that data comes in, every US agency and most doctors are going to be cautious. They'll likely advise patients to take the same booster as the first two vaccines. They'll also likely tell you to take the other one, if it's the only one available, because the limited data available says it is safe and effective.
