She’s said this even though CDC research has found that vaccinated people neither contract nor spread the virus. Specifically CDC research suggests that the mRNA vaccines from Pfizer-BioNTech and Moderna are 90% effective at preventing asymptomatic spread.
Now CDC Director Rochelle Walensky is beginning to echo her agency’s research findings. She says,
[O]ur data from the CDC today suggests, you know, that vaccinated people do not carry the virus, don`t get sick, and that it`s not just in the clinical trials but it`s also in real world data.
There’s very little to worry, then, about vaccinated people getting sick or getting others sick. There’s very little to worry, then, about vaccinated people traveling.
Vaccinated people shouldn’t even need to wear masks, except that it’s difficult to tell who is vaccinated and who isn’t, and it’ll be difficult to manage compliance by the unvaccinated up in the air. That’s why the timetable for lifting air travel mask mandates should be when there’s enough vaccine available that everyone who wants a jab can get one.
Of course if it turns out that variants are escaping the vaccines, and that this happens prior to the availability of boosters (there’s no justifiable reason for variant boosters to be delayed), guidance might need to change.
