1/ Talk about a leading question:
Why is the media assuming, without data,
that more COVID boosters = better?

The COVID vaccines are excellent at preventing severe disease, hospitalization, & death.

Even every ~6-month boosters won't prevent all infections.
2/ More here:

3/ What about long COVID?

Vaccination reduces the odds of long COVID, but doesn't eliminate the risk.
4/ If you want to prevent ALL SARS-CoV-2 infections & long COVID, you gotta wear ALL your winter❄️☃️layers:
- Vaccination💉💉💉
- Wear N95/KN95/KF94😷masks
- Socialize☀️🍃outdoors
- Optimize🪟indoor ventilation & air filtration
- Testing to isolate &💊treat infectious people

1/ CDC has shortened the recommended isolation period for COVID from 10 days to 5 days if symptom-free at 5 days
& recommends that people then wear a mask for 5 more days.

cdc.gov/media/releases…

Is this good advice?
2/ We ISOLATE people who HAVE COVID.

We QUARANTINE people who’ve been EXPOSED TO COVID.
3/ CDC recommendations are reasonable IF PAIRED with rapid antigen testing to come out of isolation.

Why? People are infectious for a wide range of time. Some for a couple days. Others, for over a week.

1/ Should people be traveling over the holidays in the midst of an Omicron surge?
with @CBSMornings' @GayleKing

Here's how my family is managing our risk AND staying safe:
- We had a big lunch🥤🍝so we didn't have to eat/drink in the airport or on the plane✈️.

1/ How accurate are the COVID rapid antigen tests?
How should you interpret the results?
with @CBS @CBSMornings' @tonydokoupil

Rapid antigen test positive➡️you have COVID

Rapid antigen test negative
BUT had a high-risk exposure or have symptoms of COVID
➡️get a PCR test
2/Here's some preliminary data from @US_FDA:

fda.gov/medical-device…

But evaluation of the rapid antigen tests vs Omicron is ongoing. ImageImage
3/ Again:

Rapid antigen test positive➡️you have COVID

Rapid antigen test negative
BUT had a high-risk exposure or have symptoms of COVID
➡️get a PCR test

🙏🏾🙏🏾🙏🏾 to the sports leagues & Bway theaters
who are testing daily, multiple times a day, with different kinds of tests.

1/ I want to see the Biden administration refocus our attention on hospitalization & death.

We've been asking too much from the COVID vaccines.

The vaccines are excellent at preventing severe disease, hospitalization, & death.

with @CBS @CBSMornings' @TonyDokoupil
2/ You are 14x more likely to die from COVID if you are unvaccinated than if you are vaccinated:

3/ You are far more likely to end up in the hospital with COVID if you are unvaccinated (blue🔵line) than if you are vaccinated (green🟢line):

1/ Why is it so hard 2 years into the pandemic to access rapid at-home COVID tests? Why are they still so expensive?

2/ IN ADDITION TO VACCINATION, we need to be testing, to identify who's contagious and needs to isolate so as not to infect others.

What can the Biden administration do to increase access to rapid at-home COVID tests?
with @PBS @NewsHour's @TheStephSy
3/ Here's what the Biden administration announced this week that it would be doing to scale up access to free at-home rapid testing:

1/ We've been asking too much from the COVID vaccines.

The vaccines are excellent at preventing severe disease, hospitalization, and death.

But the vaccines won't prevent all infections even with repeated boosting every ~6 months.
