MPR 13.05.21 CDC Fully Vaccinated Can Now Go Maskless With Some Exceptions. CDC 27.04.21 Interim Public Health Recommendations for Fully Vaccinated People. Overview Currently authorized vaccines in the United States are highly effective at protecting vaccinated people against symptomatic and severe COVID-19.
Additionally, a growing body of evidence suggests that fully vaccinated people are less likely to have asymptomatic infection or 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. For the purposes of this guidance, people are considered fully vaccinated for COVID-19 ≥2 weeks after they have received the second dose in a 2-dose series (Pfizer-BioNTech or Moderna), or ≥2 weeks after they have received a single-dose vaccine (Johnson & Johnson [J&J]/Janssen)±; there is currently no post-vaccination time limit on fully vaccinated status. Unvaccinated people refers to individuals of all ages, including children, that have not completed a vaccination series or received a single-dose vaccine.

Background SARS-CoV-2 infection is transmitted predominately by respiratory droplets generated when people cough, sneeze, sing, talk, or breathe.
CDC recommends community use of masks, specifically non-valved multi-layer cloth masks, to prevent transmission of SARS-CoV-2. Masks are primarily intended to reduce the emission of virus-laden droplets (“source control”), which is especially relevant for asymptomatic or presymptomatic infected wearers who feel well and may be unaware of their infectiousness to others, and who are estimated to account for more than 50% of transmissions.1,2 Masks also help reduce inhalation of these droplets by the wearer (“filtration for personal protection”). The community benefit of masking for SARS-CoV-2 control is due to the combination of these effects; individual prevention benefit increases with increasing numbers of people using masks consistently and correctly.

After the initial recommendation was released, high rates of cloth face covering use were reported in the United States. An increase in the rate of cloth face covering use was observed from April to May and was sustained, particularly among non-Hispanic blacks and other races, Hispanics, persons aged ≤39 years, and persons living in the Northeast. Coronavirus face masks: Homemade coverings likely need multiple layers to prevent spread.

Chris Delmas | AFP | Getty Images A homemade cloth face mask likely needs two or three layers to be effective in preventing the spread of the coronavirus, according to an observational study published Thursday in the medical journal Thorax. Researchers at the University of New South Wales in Australia looked at the effectiveness of single- and double-layer cloth face coverings at reducing the spread of respiratory droplets that pass when an infected person speaks, coughs or sneezes.
They then compared those results with that of a three-ply surgical face mask. Mascarillas 07.08 eficacia.
