Post Vaccine Social Scheduling

Title text: As if these problems weren't NP-hard enough.

Explanation

This explanation may be incomplete or incorrect: Created by a UNVACCINATED MOVIEGOER. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon. If you can address this issue, please edit the page! Thanks.

The comic shows a timeline of a multitude of (presumably) friends and acquaintances getting their two doses of vaccine. Due to the CDC-recommended delay between shots, as well as few weeks needed to build antibodies from the second shot, planning get-togethers in advance becomes complicated by who is free to meet, or not yet.

Eventually, everyone can start getting together, but during the time where some people have only received one dose, or neither dose, or their second dose recently, the scheduling is complicated.

Discussion

That third line down in the cartoon, shouldn't the first 2 be a 1? 198.41.238.116 02:56, 15 April 2021 (UTC)

Plus, should they really be going to a movie during their two weeks? NixillUmbreon (talk) 03:20, 15 April 2021 (UTC)

Third line down may have gotten a spoiled batch on their second shot (or could be lying, thereby creating errors the schedule), but it does look to me like a typo. NixellUmbreon correctly notes that Third Line also does not wait the requisite period after 2nd dose before going to a movie!

ProphetZarquon (talk) 03:50, 15 April 2021 (UTC)

Or perhaps they think that as soon as they've had their second shot, they're Good To Go? Not lying deliberately, but just plain old misinformed 162.158.165.66 04:19, 15 April 2021 (UTC)

I think the idea is because the other 2 people are vaccinated, assuming person 3 isn't at high risk, per CDC guidelines I think they're ok to socialize with vaccinated people (but that assumes there isn't anyone else at the movies) 162.158.62.199 14:51, 15 April 2021 (UTC)

Perhaps they are seeing a movie at a private residence? Thisfox (talk) 21:25, 16 April 2021 (UTC)

It seems unfair to attend any birthdays this year, considering how many could not be attended. Bobby gets a party but Susie doesn't? Hmm... Time is cruel.

Also, unrelated, but it's entirely possible that Lines 1, 2, 5, 7 & 8 are scheduling to gather on Line 3's birthday, while 3 isn't vaccinated yet.

Line 3 doesn't attend the birthday. She's going to the movie with 4 & 5 just after the 2nd shot. Every one at the bday has had the 2nd shot for 2+ weeks. 141.101.77.160 08:40, 15 April 2021 (UTC)

That's my point! It is entirely possible to schedule a birthday party for someone who cannot yet attend. Case in point: Family & friends on Earth gathering to celebrate the birthday of an astronaut in space, who can only view the goings-on via a bandwidth-limited single-feed video chat. With CoViD '19 happening, who knows how many people have tried to schedule a surprise party only to discover that the birthday person won't be vaccinated in time? Mind you, I'm not saying it's the most likely scenario (far from it), I'm merely pointing out that with so many still unable to attend, it's entirely possible to schedule a party for the birthday of someone who can't attend.

Edit: Also, also, what is a chungus? (I don't come to explainxkcd because I want to search random words on DuckDuckGo...) ProphetZarquon (talk) 03:50, 15 April 2021 (UTC)

according to dictionary.com, “Chungus is a meme featuring a chunky version of the cartoon character Bugs Bunny, typically captioned Big Chungus. It began as gaming joke that spread online as a slang term for anything ‘(adorably) chunky,’ similar to chonky.“ (which begs the question, what does that have to do with the explanation of this comic being written by a “big chungus”)162.158.62.233 04:18, 15 April 2021 (UTC)

Just wondering, how is Big Chungus related to this? Confuuusion Eelitee (talk) 04:29, 15 April 2021 (UTC)

Sooo... "Chungus" seems unrelated to anything in the comic, & was replaced in the bot tag so it no longer appears on the explanation page. Maybe it was just some idle defacement by an early visitor to the comic's explanation? It's a weird term: I don't see any use of it except in reference to this single appearance of a fattened Bugs Bunny, the phrase is not spoken in the cartoon & as a portmanteau "chunky" seems a clear contributor, but the latter half is less clear. (Misspelling of "ous" from "humongous"? Does not seem to get applied to humongous things, as often as small things that are fat, though... "bulbous"?)

Question as a European: Don't Americans use the Johnson & Johnson vaccine which just needs 1 shot (in addition to those that need 2 shots)? Everyone in this chart gets a "2" shot (and in the case of the 3rd person even two "2" shots.) --Lupo (talk) 05:03, 15 April 2021 (UTC)

When scheduled for an immunisation an American may find that they are being administered Moderna, Pfizer, or until recently the J&J vaccine (currently that rollout is paused until an investigation into blood clot incidence can be concluded). The second shot if it exists needs to be the same as the first, but otherwise there is little local favouring of one manufacturer over the others. 172.69.33.77 06:36, 15 April 2021 (UTC)

Thanks for the information, but my question was about how J&J is applied (if it is applied at all), as to my knowledge it doesn't need a 2nd shot, but is fully functional few weeks after the first shot. But noone in this graph is getting only 1 shot. So it looks like this graph already ignores J&J/depicts a group of people in which noone got J&J. --Lupo (talk) 06:39, 15 April 2021 (UTC)

J&J makes up < 5% of administered vaccines in the US even prior to the CDC freeze, so its not surprising that in a group of 11 people they all received either Moderna or Pfizer 162.158.62.199 14:51, 15 April 2021 (UTC)

The people I know who've received the J&J vaccine were still advised to get a second dose (not that it's available).

ProphetZarquon (talk) 17:58, 15 April 2021 (UTC)

I thought this comic was also about the CDC guidance even after getting vaccinated to stay in small groups, this, there is no group of > 4 people or so. 172.69.35.143 05:17, 15 April 2021 (UTC)

Cabin and birthday are 5 people each. --Lupo (talk) 05:20, 15 April 2021 (UTC)

Hmm, but by "Cabin" everyone has already been vaccinated. So should've they all be able to attend? 172.69.33.19 05:31, 15 April 2021 (UTC)

Everyone still doesn't want to go everywere. If I'd schedule a Transformers movie night I'd only got most of my brothers to join and maybe two of our significant others. Also some may be unavailable for other reasons to which the alt-text seems to refer. 162.158.238.244 07:55, 15 April 2021 (UTC)

Might this also a take on the transistor 'NPN hole' diagram? The title text states 'NP-hard' which is something different, but the diagram does look a little like transistor holes and electrons! Emitter's and Collector's? Fan2012 (talk) 06:21, 15 April 2021 (UTC)

Hm, is this possibly the Boolean satisfiability problem (as in whether or not someone can come is TRUE or FALSE)? This is a NP-hard problem: https://en.wikipedia.org/wiki/Boolean_satisfiability_problem 172.68.132.195

Could somebody send this recent book by a whistleblower to Randall? He could make so many jokes: https://books.google.com/books/about/Mindf_ck.html?id=8AqmDwAAQBAJ 162.158.62.13 12:18, 15 April 2021 (UTC)

Judging by the size of the gaps, 2, 7 & 8 presumably receive Moderna, while the rest receive Pfizer (for the pedants: yes, there are other possible explanations for the discrepancy in gaps, but this is the simplest). Does someone have a way of checking whether this roughly mirrors the prevalence of the two vaccines in the US up to mid-April?

From https://covid.cdc.gov/covid-data-tracker/#vaccinations as of April 16 6:00AM EST fully vaccinated numbers were Pfizer 39.440M, Moderna 33.333M, J&J 7.798M. For 11 people the best fit would be 5:5:1.

We do not know if the sample is representative of the US population, but if it is we can use todays 24% fully vaccinated (actually 2 doses without the further 2 week wait) place April 16 in the first quarter, near the time the bottom person gets their 2nd dose.162.158.78.160 20:01, 16 April 2021 (UTC)

Anyone concerned for the four people that Black Hat is taking to a cabin? 141.101.98.16 17:56, 15 April 2021 (UTC)

I'm more concerned that I'm not going. Danish (talk) 17:58, 15 April 2021 (UTC)

There are really 5 people plus Black Hat since the person sponsoring the event is not on the chart and will also be there. I am assuming that the person doing the arranging is doing it for personal benefit and will be attending all the events. Rtanenbaum (talk) 02:24, 16 April 2021 (UTC)

Not an obvious conclusion. In organising one's own line (Danish from the top line, or perhaps the Danish+Cueball couple, centred entirely on hosting/attending the Birthday event?), you're drawn into accounting for everyone else who might be there and their other potential commitments. Possibly extending to friends-of-friends (Blondie, other Cueball and Meghan? ...justifiable as not even pass-through members of Birthday?) who wouldn't be expected to be birthday guests but need to be figured in as potential confounding factors.

Alternatively, as typical author+partner avatars, Cueball+Meghan at the bottom are arranging a couple of part-shared meet-ups and it has been extended upwards to account for proxy-associationz (including the Birthday, which isn't on their own radar). Though I find the connective topology of the (definite) links slightly less convincing in support of this version.

(i.e. bottom-up and its subsequent accumulation of activities/people is less convincing, when compared to the top-down interpretation of Hairbun unfortunately being shown necessary to skip the main Birthday bash; Black Hat and Science Girl maybe only included high up as known linked persons, via their intended involvement in the Movie/Cabin/etc...)

There are other possible starting assumptions (positionally, it could have 'started' with any single character's line, extended up and down as deemed necessary when more linked events and individuals were discovered) but none appear to be quite as logically satisfying. YMMV. 141.101.107.80 08:15, 16 April 2021 (UTC)

Sorry, but this looks for me not only like a Sorting network, but it would also give the NP-problem reference more sense. Enkidu (talk) 11:47, 16 April 2021 (UTC)

Beyond Scheduling: There may still be transmission after vaccination, particularly of VoC ( Variants of Concern ) https://youtu.be/JtseAUamHqI
