Covid breakthrough data based on vaccine type?

32. Please stop saying that the CDC is recommending that people ignore exposure unless symptomatic.

That might be what you (or other people) are hearing, but it is not what the CDC is saying.

It mischaracterizes the CDC interim public health recommendations for fully vaccinated people. There is a distinction between "recommending that people ignore" and recommending that they "can refrain from".

Fully vaccinated people can:

- Resume activities without wearing masks or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules and regulations, including local business and workplace guidance

- Resume domestic travel and refrain from testing before or after travel and from self-quarantine after travel

- Refrain from testing before leaving the United States for international travel (unless required by the destination) and refrain from self-quarantine after arriving back in the United States

- Refrain from testing following a known exposure, if asymptomatic, with some exceptions for specific settings

- Refrain from quarantine following a known exposure if asymptomatic

- Refrain from routine screening testing if feasible

For now, fully vaccinated people should continue to:

-Get tested if experiencing COVID-19 symptoms

- Follow CDC and health department travel requirements and recommendations

Guiding Principles for Fully Vaccinated People

- Indoor and outdoor activities pose minimal risk to fully vaccinated people.

- Fully vaccinated people have a reduced risk of transmitting SARS-CoV-2 to unvaccinated people.

- Fully vaccinated people should still get tested if experiencing COVID-19 symptoms.

- Fully vaccinated people should not visit private or public settings if they have tested positive for COVID-19 in the prior 10 days or are experiencing COVID-19 symptoms.

- Fully vaccinated people should continue to follow any applicable federal, state, local, tribal, or territorial laws, rules, and regulations.

The situation is fluid, the recommendations have changed and will continue to change, and people are free to take whatever additional precautions they see fit based on their comfort level and their anticipation of what the future may bring. I am fully vaccinated and I still mask. (Quite recently I was followed down a street in NYC by a group of unmasked anti-vaxxers who were harassing me for being masked in an outdoor space.)

It is perfectly fine to critique the CDC and important to note that they are not infallible and that they have made mistakes. What I object to is undermining confidence in public health professionals by mischaracterizing what they are doing and what they are saying. There are many, many people who are "doing their own research" and then "reporting their findings" in public spaces. It can be a dangerous thing.

"I didn't wait for the CDC to wake up to aerosolized transmission to start avoiding being unmasked in indoor spaces "

In 2021, a long-accepted medical principle was revised by the work of a group of tenacious scientists and researchers who challenged the standard model concerning aerosols. Their collaboration began in the late winter/early spring of 2020. In July 2020, the group went public with an open letter expressing their concerns about the standard model.

On April 14, 2021 an editorial was published in the BMJ entitled "Covid-19 Has Redefined Airborne Transmission", based on the April 2021 publication of the group's research, "How Did We Get Here: What Are Droplets and Aerosols and How Far Do They Go? A Historical Perspective on the Transmission of Respiratory Infectious Diseases".

On April 30, 2021 the WHO updated its section on how the coronavirus is transmitted, stating that the virus can spread via aerosols as well as larger droplets. The CDC followed suit in early May 2021.

The CDC made its recommendation that people wear masks in public on April 3, 2020, at the same time the science-changing research was fully undertaken and a full year before the findings were published. There was no "lag in reacting to predominant data".

The CDC mask recommendation predated both the publication of the groundbreaking data and indeed its own updated science-based information of how covid spreads.
