🔺CDC INTERIM GUIDANCE FOR FULLY VACCINATED🔺

🧵🧵🧵

1/ Much anticipated guidance released today from CDC for those who are fully vaccinated (> 2 weeks after second dose Moderna/Pfizer, or single dose J&J) - link below + more details/thoughts

cdc.gov/coronavirus/20… Image
2/ Here are the key recommendations but I urge you to click the link to read more details about each of these scenarios/ situations #covid19 ImageImage
3/ Important graphic here summarizing private gatherings among those who are all vaccinated or if you have a combination of fully vaccinated + unvaccinated AND low risk in small private setting

The latter would hinge on vaxx being unlikely to spread (although not impossible) Image
4/ And the reason this calculus would change if there’s any high risk person in the home is because even w/ the smaller risk of spread, the chance for a bad health outcome for a high risk unvaxx’d person is still there. #covid19
5/ “For example, fully vaccinated grandparents can visit indoors with their unvaccinated healthy daughter and her healthy children without wearing masks or physical distancing, provided none of the unvaccinated family members are at risk of severe #COVID19.” Image
6/ The CDC recommends against maskless medium or larger gatherings but don’t give absolute numbers on this

Helpful to think in terms of rate of community spread, number of people, duration of time, ventilation indoors, and distancing

cdc.gov/coronavirus/20… Image
7/ while they acknowledge that other activities, like gyms & restaurants, are lower risk for vaccinated people, with high rates of community #covid19 transmission, precautions still must be taken in these settings until we have reached much higher levels of vaccination Image
8/ the WHY 💉💉💉

“Currently authorized vaccines in the US are highly effective at protecting vaxx’d people against symptomatic & severe COVID-19. Additionally, a growing body of evidence suggests that fully vaccinated people are less likely to have asymptomatic infection...”
9/ “& potentially less likely to transmit SARS-CoV-2 to others. How long vaccine protection lasts and how much vaccines protect against emerging SARS-CoV-2 variants are still under investigation.”

Waiting to understand duration/strength of immune protection
10/ “Until more is known and vaccination coverage increases, some prevention measures will continue to be necessary for all people, regardless of vaccination status.”

11/ Get vaccinated!

Vaccines are the most important tool we have right now.

Efforts should be focused on ramping up our vaccine distribution even further.

If you have been 💉💉 please speak to your close circles if anyone is hesitant so they can know it’s safe. #covid19

1/ Some have asked why fully vaccinated can only visit with “a single household” of unvaccinated people who are low risk.

We still have high rates of circulating virus in community. Unvaccinated low risk people can still get sick/ pass on virus more than those who are vaccinated
2/ By having multiple unvaccinated households gathering w/ vaccinated person(s), you are then again creating a higher risk setup for disease transmission
3/ Also, vaccinated people can also still pass virus onwards, although less so than those who are unvaccinated.
This is why CDC is being very specific to say small gatherings with *low risk* unvaccinated has a cost/benefit in favor of social connection given low chance of harm

Spoke w @HarveyLevinTMZ @charleslat @TMZLive regarding the role of athletes & public figures in addressing vaccine hesitancy, the focus here being on Lebron James’ recent decision to keep his vaccination decision private. #covid19 (part of conversation here)
2/ I recounted the story of my recent Lyft driver who asked about vaccines and said he didn’t trust politicians or the pharmaceutical industry. But we still had a productive conversation. And it ended w/ him a little closer to getting vaccinated. #covid19
3/ This brings up an interesting ethical dilemma re the role of public figures like athletes or movie stars etc who have significant influence - & who people may actually end up trusting or following more than politicians & others who have been politicized during the epidemic

🧵 1/ This morning in my Lyft to the hospital, my driver asked me about the #covid19 vaccines.

He said he was skeptical, both of the pharmaceutical industry, and even more so of politicians.

I often wonder how many conversations like this happen informally every day.
2/ He then asked me about hydroxychloroquine. He referenced the previous administration’s pushes for this. He asked if it worked and actually said he heard about a doctor in Texas that was “curing” patients with it.
3/ I encouraged him that the vaccines were in fact safe- I reassured that I had taken it over a month ago now & I was fine, as were all of my colleagues who have been vaccinated at work thus far. I tried to explain why hydroxychloroquine was not in fact a “cure” for #covid19

🧵🧵1/ When people ask which mask is “good enough”, I often try to reframe it as better protection is better protection; everything we are doing is to reduce risk.

Is an N95 better than a cloth mask? Yea, it is

Is a cloth mask better than no mask? Yea, it is

#covid19
2/ If there was a good reason to not wear an N95 or equivalent mask during indoor crowded activities, then we wouldn’t be pushing for it.

But frankly, most of the reasons presented have been weak.
3/ The CDC Director on CNN once said it was bc they are hard to breathe through.

I don’t think so

I have worn them for hours at a time in the hospital

We are calling for people to wear them when in higher risk indoor settings. This likely won’t be for hours most of the time

🧵 1/ Presumed #covid19 reinfection (first cases mild, second cases more severe) in five elderly Kentucky nursing home residents w/ multiple co-morbidities, > three months apart.

New in @CDCMMWR

cdc.gov/mmwr/volumes/7…
2/ The patients were elderly with multiple chronic health conditions.

They had confirmed infections in a July outbreak at their nursing home- these were described as very mild, w/ only 2 having symptoms at all.

They had at least 4 negative PCR since their first pos tests.
3/ The second outbreak started at the same SNF on October 30th.

5 tested positive again, 3 with known roommate exposures.

7 who were previously infected did not test positive but further details about them (did they have more severe initial cases?) not included.

🧵 1/ So I read this @BostonGlobe story today about what is going to be reopening in Massachusetts on Monday - restaurants will have *no capacity limit* and can host *musical performances*(??)

Hmm interesting.

So I decided to check again what % we have vaccinated #covid19 ...
2/ So we are at 6.2% in terms of people who have received two doses; 16% for those who have received one dose

So...we aren’t even close to where we need to be for vaccinations, we got lucky to see a rapid decline in cases, but now we are rapid reopening

nytimes.com/interactive/20…
3/ I then took a look at the waste water surveillance data, which tends to precede detected cases— possibly a slight uptick here in the last few days?

All this to say: a decrease in cases should still mean—> scale up vaccinations while temporizing spread
