Is it OK for vaccinated people to
meet with other vaccinated people?
The CDC guidelines and experts
agree that once fully vaccinated—at
least two weeks after your second
dose of the Pfizer or Moderna vac-
cines or the single Johnson & John-
son shot—it’s safe to meet indoors
with other fully vaccinated people
without masks or distancing.
Gathering with other vacci-
nated people is “scientifically very
safe,” says Paul E. Sax, clinical di-
rector of the division of infectious
diseases at Brigham and Women’s
Hospital in Boston. Nothing is
100% effective but “gathering with
other vaccinated people is pretty
darn close,” he says.
“I don’t think people should run
to a crowded bar where people are
shouting at each other,” he says.
“But the kind of socializing that is
part of human
nature and that
has been put on
hold for a lot of
people—that can
resume.”
The larger
the group, the
riskier the inter-
action, because
you can’t verify
that everyone is vaccinated and
you don’t know what their expo-
sures are, says Leana Wen, an
emergency physician and public
health professor at George Wash-
ington University in Washington,
D.C. The CDC guidelines say pre-
cautions such as wearing masks
and social distancing should be
taken for medium and large gath-
erings despite the vaccination sta-
tus of individuals.

disease physician and professor of
medicine at the University of Cali-
fornia, San Francisco, is less con-

plants and soil. Those include or-
ganic compounds, pollen, fungi and
bacteria that contribute to the di-
versity of microorganisms humans
need for a robust and diverse mi-
crobiome—all the tiny living things
on us and in us
that protect us
from disease. So
just breathing
forest air may
help strengthen
our immune
systems, accord-
ing to a review
published in
February in the
International
Journal of Environmental Research
and Public Health.
The benefits don’t just occur in
forests. Scientists define nature as
all sorts of environments dominated
by living material, from a small ur-
ban park to the wilderness, accord-
ing to research. Their definition of
“nature exposure” ranges from
plants in a room to camping trips to
virtual reality.
That means you are likely to get
some nature benefits from garden-
ing, kayaking or even on a motorcy-
cle, assuming it’s out in the country,
says Dr. Minson. A lot more research
is needed to know just how much.
