UC San Diego Data

Here’s the COVID data collected from the end of Autumn (Social Psych sample & Health Psych/Pre-Med sample) through Winter Quarter (Intro Psych sample). All the extra fluff is down in the sidenotes section, per usual.

1. Masks As Long Term Behavior Change

- Most students (by a margin of 271 to 21) indicated that they plan to continue wearing masks in the years after COVID19 has ended whenever they go to work sick, have to work around sick colleagues, and/or sit next to a sick person on public transportation.

2. Introverts Want to Continue Social Distancing After COVID Ends

  • Introverts should be given accommodations to allow them to return to social life at their own pace. From a mental health standpoint, it’d be healthier to wean introverts off their me-time gradually rather than expecting them to part with such a significant amount of me-time overnight.

3. Students Are MultiMasking (and Fashion Masks Don’t Seem to Make a Difference)

- Like myself & Dr. Fauci, most students indicated that they’re multimasking

4. Course Modality Preference When We Return

- Most students want to return to in-person/ indoor… a finding that surprises no one. However…

Most students indicated that they want some form of online course option to continue to exist as an (at-will/ any given day) option for any class they may be taking.

Others indicated they’d prefer an online option…

Given that introverts already have their cameras off more, it makes sense they’d be less interested in using Zoom in the future.

5. You Can’t Sit With Us Without a Vaccine Passport (Vaccine Sterilizing Immunity)

A minority of students suggest that vaccination status may become a relevant social category for the next year or 2 & that people may use vaccination status (or lack thereof) as a way to escape bad dates.

6. COV-Eye-D

- Many students who didn’t wear glasses began wearing them to avoid the risk of ocular infection. This includes students who switched from contacts to glasses, those who purchased non-prescription fashion glasses to wear over their contacts, & those with absolutely no medical need for glasses but purchased fashion glasses simply for protection. (Note: Glasses don’t provide the same protection as goggles, and the risk of ocular infection is substantially lower than the risk of infection via the nose. Nose > Mouth > Eyes)

7. Human Space Avoidance (Recognizing Implied Social Environments)

- Students indicated avoiding walking on sidewalks (even if it’s empty, you know someone walked there at some point)
- Reparking their car if someone inexplicably parked next to them when there are other wide open spaces more than 6 feet away,
- Getting in front of a group that was talking as opposed to remaining downwind of them.

Vaccine Passports: Protection, Not Preference

I’m fully vaccinated now (1st Pfizer on Feb 21; 2nd dose March 14; efficacy should be complete by March 28th) & started wearing the new free faculty mask to commemorate my vaccination against this monster. Masks are still required given that the vaccine does not confer sterilization immunity.

Student Confidence

Unless someone is wearing their CDC card around their neck like I am (with 2 stickers showing to indicate 2 shots), there’s no way to know if someone is safe or not. Thus, wearing my Vaccination Card during lecture this fall will let students know it’s safe to come ask me questions at the podium after class.

Fall 2021 Exam Grades

Students first exam this Fall will be their first in-person, crowded room, paper/scantron/blue book, pen/pencil, closed notes/ closed Siri, exam they’ve had in 18–19 months.

Long COVID19

National Institute for Health Research March 16th, 2021


Long Covid is a group of four possible syndromes affecting patients differently.

The best vaccine is one that elicits high concentrations of neutralizing antibodies and maintains those high amounts forever. For any antibody neutralization sensitive pathogen.


Viruses can change through mutations. These mutated forms of a virus are called variants.

Sterilizing Immunity — Jennie Lavine et al., 2021

“Building on ideas from the vaccine modeling literature, we suggest that immunity may provide protection in three ways (Halloran et al., 2010). In its most robust form, sterilizing immunity can prevent a pathogen from replicating, thereby rendering the host refractory to reinfection. We term this property immune efficacy with respect to susceptibility (IES). If immunity does not prevent reinfection, it may still attenuate pathology due to reinfection (IEP) and/or reduce transmissibility or infectiousness (IEI). Indeed, experimental reexposure studies on endemic HCoVs provide evidence that the three immune efficacies do not wane at the same rate (Callow et al., 1990; Bradburne et al., 1967). Callow et al.’s experimental study shows that reinfection is possible within one year (relatively short IES); however, upon reinfection, symptoms are mild (high IEP) and the virus is cleared more quickly (moderate IEI).”

Huffpost UK — 3.12.2021

“The study assessed the records of people who live with both vaccinated and unvaccinated healthcare workers, and found the rate of Covid-19 among them was at least 30% lower when the health worker had had a single dose.

India Serology Tests

The survey of more than 35,700 people above 10, conducted in the last two months, gave a much lower estimate for the average number of people to have contracted COVID-19 than other research.

(Given that we may not know everything about sterilization immunity & risk of infection post-vaccination, this is just my personal storage of additional pieces of info. Posting in this area DOES NOT MEAN AGREEMENT — it just means I’m storing it so it’s easier to revisit. It also means things will be deleted once their scientific and/or public health utility has eroded in the wake of better information)

Visits between fully vaccinated people and unvaccinated people

Indoor visits between fully vaccinated people and unvaccinated people who do not wear masks or physically distance from one another are likely low risk for the vaccinated people.

Therefore, the level of precautions taken should be determined by the characteristics of the unvaccinated people, who remain unprotected against COVID-19.

Though the risk of disease may be minimal to the fully vaccinated person themselves, they should be mindful of their potential risk of transmitting the virus to others if they become infected, especially if they are visiting with unvaccinated people.
