Vaccines
Here is an article comparing the vaccines 2.27.21 from Yale
TLDR:
Pfizer (updated 5.19.21) : 12 and over. testing in 12-15 y/o. 2 shots 21 days apart. mRNA. 95% efficacy in preventing COVID19 in those who have never been infected. 100% effective at preventing severe disease. Effective agains B117 (Great Britain) may be less effective agains South Africa strain B.1.351
Moderna. MRNA. 86% effective in 65 and older. 2 shots 28 days apart. 94.1% effective in preventing COVID19 in those who have never been infected. may provide protection against the B.1.1.7 and B.1.351 variants.
Johnson & Johnson. virus vector. 18 and older. 72% effective overall. and 86% against severe disease. Protects agains B.1.1.7. 64% overall efficacy and 82% efficacy against severe disease in South Africa, where B.1.351 was 1st detected.
the case for vaccination. No one has died from the vaccines. 2.7 million people have died in the world from COVID. 541,909 have died in the US from COVID as of 3.20.21. 41.9M have been fully vaccinated in the US against COVID.
Protection after 1 dose of vaccine
From NEJM 2.17.21
vaccine efficacy after 1 dose:
92.6% BNT162b2 (Pfizer)
92.1% mRNA-1273 vaccine (Moderna)

Almost all COVID is spread person to person and very little spread via surfaces. from NYT article updated in Nov 2020.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7291777/ “SARS-CoV die-off on dry surfaces is rapid over time with ~ a 90% loss over the first 24 h.
If you leave the bag aside for 3 days, most COVID should be dead. To be extra safe you could set it aside for 5 days.

Limitations: does this take into account the NEW strains that infect younger people more than the older strain?
This is the risk amongst 23andme users, who I think are more affluent and less likely to end up hospitalized and have better access to healthcare.

Unfortunately, experts per Mayo Clinic estimate that it would take 70% of the US population to be infected (200 million people) to have herd immunity to prevent the spread of COVID19.
If you’re waiting/expecting Herd Immunity by natural infection, it’d take a LOT of people.

Background on the COVID-19
Although first detected in Wuhan, China, COVID-19 (also known as the “coronavirus”) has spread throughout different countries and was just declared a pandemic by WHO. It is important to take simple precautions and be aware of prevention methods and symptoms in order to protect yourself and those around you.
How COVID-19 Spreads
Coronavirus Disease 2019 (COVID-19) is thought to be spread by respiratory droplets when an infected person coughs or sneezes. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or eyes, but this is not thought to be the main way the virus spreads.

Who’s Affected by COVID-19
Although the virus can affect people of all ages, sex, or ethnicity, there are risk factors that can increase the likelihood of a person dying from the virus.
Risk factors: The risk is mainly in those 50 and older and who have underlying chronic heart/lung diseases, diabetes, and/or cancer. To provide some peace of mind to parents, there have been NO deaths in those ages 0-9 years old. And the death rate for those 10-19 years old is 0.2%
Symptoms of COVID-19
Symptoms of COVID-19 include:
- Fever
- Persistent Coughing
- Shortness of breath
Symptoms may start 2 to 14 days after exposure to the virus. If you have body aches so severe that you feel like you got run over by a car, you most likely have the flu and NOT COVID-19.
Note: these symptoms are common with other illnesses like the flu or common cold. If you have one or more of the above symptoms, it does NOT mean you have COVID-19.
Great resource with statistics on Symptoms of Hospitalized patients: https://www.worldometers.info/coronavirus/coronavirus-symptoms/
From “Is it allergies, the flu, or coronavirus COVID-19?“
Anosmia = loss of sense of smell
“pre-publication findings from the 1.5 million users of Kings Colleges the Covid-19 symptom tracker app that 59% of those with a positive test for the virus reported loss of smell (and impact on taste) [3]. A survey of appr 10,069 Iranian subjects shows a correlation of 0.87 (p<0.001) with smell and taste loss [4], and an Italian smaller study again reports similar findings. The latter suggests what seems to be the emerging hypotheses around COVID-19 related anosmia, that is the binding of COVID-19 to ACE2 receptors (which are plentiful in the naso-pharyngeal tract) that accounts for the uniqueness of this symptom, and that it is not just secondary to a mucosal build up that could occur in any flu-like virus [5].”
source: https://www.bmj.com/content/368/bmj.m1202/rr-1
What it looks like in clinic from Dr. Uché Blackstock in NY
Fever, headache, dry cough, muscle aches, fatigue, some with loss of smell and taste and diarrhea. Fluctuating course. By day 5, shortness of breath & chest tightness. Shortness of breath worsens around day 8-10. Many hypoxic in low 90s with bilateral infiltrates in chest X-ray. CT is best though.
80% of cases are mild
Based on all 72,314 cases of COVID-19 confirmed, suspected, and asymptomatic cases in China as of February 11, a paper by the Chinese CCDC released on February 17 and published in the Chinese Journal of Epidemiology has found that:
- 80.9% of infections are mild (with flu-like symptoms) and can recover at home.
- 13.8% are severe = severe diseases e.g. pneumonia and shortness of breath.
- 4.7% as critical and can include: respiratory failure, septic shock, and multi-organ failure.
Most cases are undetected (we don’t have the tests) and possibly asymptomatic. “If we have 3,500 confirmed cases in the U.S., you might be looking at 35,000 in reality,” said Jeffrey Shaman, senior author Science Magazine. The milder cases are “half as infectious but cause 80% of the cases.” https://www.nytimes.com/2020/03/16/health/coronavirus-statistics-undetected.html
Tips & General Precautions
(from NYT)
- Wash your hands properly (watch this video) and at least for 20 seconds with soap and water.
- A 2006 study found that hand washing can cut the risk of respiratory infection by 16 % and a 2008 study showed a 21 % decrease.
- Hand washing with soap and water are preferred by the CDC over hand sanitizer.
- Hand sanitizers may be helpful, if they contain at least 60% alcohol.
- Touch your face (eyes, nose, mouth) less.
- Stay 6 feet away from anyone coughing/sick. Don’t shake hands.
- If you have a fever and cough, stay home if you can.
- Make sure you have food for 14 days e.g. canned goods, frozen goods.
How to avoid COVID-19 on a plane: (from CDC)
- Wipe down the arm rest, the tray table, the buckle, air vent, and if you are on the window, the window area that you might lean against/touch.
- Don’t touch your face (eyes, nose, mouth), with unwashed hands.
- It is especially important to clean hands after going to the bathroom; before eating; and after coughing, sneezing, or blowing your nose.
Stock Up on Important Medications
Former Head of CDC, Tom Frieden, M.D., M.P.H., recommends that people secure a 3-month supply of important medications. Getting your 90-day prescription delivered can save money & eliminate trips to the drugstore/pharmacy/doctors office– where you might encounter people who are sick. Friedmen suggests discussing with your insurer if your coverage offers an extended-day supply.
If you have an active birth control prescription, get your refills delivered straight to your mailbox. Avoid places that you may encounter sick people, such as the pharmacy or doctor’s office. Delivery is always FREE and we take most insurances. Depending on your insurance, we can provide you 3, 6, or 12 months worth of birth control in one mailer.
If you need a birth control prescription, no need to go into the doctor’s office. For those in Arizona, California, Colorado, Florida, Georgia, Nevada, Texas, Washington, and Wyoming, Pandia Health’s team of expert birth control doctors can write you your prescription (if safe). All you have to do is answer 20 health questions from the comfort and safety of your own home — safe & confidential. Sign Up Today!

For fever, start with acetaminophen and avoid ibuprofen and NSAIDS, if possible 3.19.20
start with acetaminophen. BUT know that too much acetaminophen can hurt your liver. and do NOT stop NSAIDS if you are prescribed by your doctor unless you consult your doctor first.
The risk is theoretical based on COVID attaches to ACE2 and that ibuprofen and NSAIDs increase ACE2 receptors. However, Rachel Graham PhD, a virologist at University of North Carolina School of Global Public Health. and one of the researchers who discovered how the coronavirus binds to cells, the evidence that taking ibuprofen increases these receptors is almost nonexistent.
However, Dr. Angela Rogers, a pulmonologist at the Stanford University Medical Center and chair of its intensive care unit’s COVID-19 task force said that acetaminophen is the go to medication in the ICU because NSAIDs can cause kidney damage and acetaminophen does not have that risk.
Social distancing versus isolation vs quarantine
social distancing = distancing to protect yourself and others
isolation = distancing to protect yourself and others withOUT having a +COVID test
Quarantine = you have been tested and tested POSITIVE for COVID and you are mandated to stay at home/away from others
Cloth re-usable 3 layer mask, if you can sew
Cloth is not as good as surgical masks. Surgical masks have 97% effectiveness against 1 micron particles.

to be used for “everyday” when you do NOT know if someone has COVID e.g. grocery store or any line in a public place e.g. pharmacy.
If you are around someone that has COVID and in the hospital, then do NOT use a cloth/re-usable mask.
But this could work for outpatient settings when you do NOT know whether someone has COVID yet.
- Wash fabric masks each day
- Replace non-woven layer with a fresh one– do NOT reuse!
- Do not wear masks if you have respiratory illnesses
- Save the surgical masks for medical professionals who are on the front line of healthcare, and use them only when you need to
- Washing your hands often– it’s more important than wearing a mask.
For the non-woven layer, some examples:
coffee filters, dried out wet wipes (unscented), brand new polyester floor wipes (dry ones), or even non-woven gauze from the pharmacy.
Fabric masks need to be washed and worn carefully like you would a surgical mask:
- Wash and dry your hands before putting on and removing the mask
- Be careful that you don’t contaminate the inside of the mask
- Practice good hand hygiene as best as you can!
- Any type of masks (N95, surgical, fabric) shouldn’t be worn too long. When it gets damp, you should replace it. So, if you’re sweating a lot, prepare extra masks.
Use a surgical mask if you are:
- Sick and have to be around other people
- Healthy and you’re heading to a very crowded area or a place with COVID tested positive people

Wear surgical mask blue side out 6.15.20
Now that Costco is selling surgical masks, if you have one, wear it with the blue side out. The Blue side has the water resistant side and thus will filter more particles out. Thomas Talhelm of U of Chicago tested it and it makes from 1.7% on average to 5.2% difference in filtration.
What if both sides are white? then the rough side faces out.
How long can COVID survive in air, on surfaces?
This is based on lab research and may not reflect the “real world.” but here’s a great summary.
High Temp, dry, wind = bad for COVID
Because it has a fat layer on its outside, it can dry out. So High temperatures e.g. 99 degrees Fahrenheit drops its life span to 1 day. Low humidity and wind can dry it out. https://www.businessinsider.com/how-long-can-coronavirus-live-on-surfaces-how-to-disinfect-2020-3

How to use gloves properly
Tips from Jacquelyn Gill, scientist who uses gloves to avoid lethal chemicals at work
#1 One of the most important things to remember: the point of gloves is not to not prevent you from “absorbing” the virus through your skin. If your skin is hydrated and you don’t have open wounds, your body’s natural defenses will prevent transmission through your skin. (With all the handwashing, your hands may be cracked and dry: keep them hydrated with heavy duty hand creams!)
#2 why wear gloves? They’re disposable! If you touch a surface lots of other people touched, like a pin pad at a checkout counter or a door handle, you can throw them away and avoid transmitting any germs (like coronavirus) to your phone, face, car door, debit card, keys, etc.
#3 Gloves will NOT prevent you from transferring germs from a contaminated surface to a contaminated one! Gloves aren’t anti-microbial. If you touch a doorknob with gloves on, then touch your face WITH THOSE SAME GLOVES, you’ve transmitted germs from the doorknob to your face.
#4 DO NOT do the following with gloves AFTER touching a contaminated surface: a. opening a soda bottle and taking a drink b. touching your glasses c. adjusting masks d. touching your car keys, debit card e. using your phone
#5 The only way gloves are effective is if you change them as often as you should wash or sanitize* your hands. Read that out loud. Again. Make it stick. *Good hand-washing with soap is more effective than sanitizer, but it’s not always something we can do outside the house.
#6 do NOT re-use gloves. throw them away.
#7 A lot of folks are asking about washing and re-using disposable gloves: Think of them like condoms, folks. Single-use and disposable. That’s what they were designed for. They start to wear out and and fail rates increase within 15-30 minutes. That’s why hospitals need so many.

“In Hong Kong, “close contact” means fifteen minutes at a distance of less than six feet and without the use of a surgical mask; in Singapore, thirty minutes. If the exposure is shorter than the prescribed limit but within six feet for more than two minutes, workers can stay on the job if they wear a surgical mask and have twice-daily temperature checks. ” reference https://www.newyorker.com/news/news-desk/keeping-the-coronavirus-from-infecting-health-care-workers
