fully vaccinated people can venture outdoors without masks, according to updated guidance from the Centers for Disease Control and Prevention issued Tuesday. The guidance applies to fully vaccinated individuals, which health officials classify as two weeks after the second dose of the Pfizer or Moderna vaccines and two weeks after the single-dose Johnson & Johnson vaccine. CDC cannot provide the specific risk level for every activity in every community, so it is important to consider your own personal situation and the risk to you, your family and your community before venturing out without a mask, CDC director Rochelle Walensky said in prepared remarks.
He cited the case of an unnamed “otherwise healthy adult” who became re-infected six month after the initial bout with the disease “despite production of neutralizing antibodies after the first infection. This individual apparently spread COVID-19 while re-infected.”
With this in mind, Mermel wrote that once herd immunity is reached by means of vaccines and “natural disease,” universal masking should continue in congregate settings and other indoor settings where social distancing cannot be maintained and/or the introduction of fresh air introduced into the environment, or filtration of recirculated air, is suboptimal.”
Mermel said that “widespread vaccination will inevitably reduce the COVID-19 reproductive number, thereby changing the transmission dynamics in many parts of the world. However, infection among those unvaccinated and reinfection in unvaccinated and vaccinated individuals remains an ongoing concern.”
