Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent

Introduction
Controlling the spread of infectious diseases involves both pharmaceutical and non-pharmaceutical
measures. The pharmaceutical measures involve vaccination. The most effective non-pharmaceutical
measures involve social distancing and source controls.
Vaccination reduces the risk of infection but does not eliminate the possibility of reinfection or of
asymptomatic transmission of the virus to others, nor does it provide immediate protection to the
vaccinated. Herd immunity has been elusive despite vaccination campaigns for several reasons:
a) vaccination protection is less effective over time;
b) it is possible that vaccinations do not protect against emergent variants;
c) pre-existing health conditions, including immunosuppression can make certain individuals more
susceptible to infection;
d) individuals can choose not to receive vaccinations.
In times of increased incidence of active cases, non-pharmaceutical infection control measures are helpful.
For individuals who are most susceptible, personal protective equipment such as respirators can provide
additional protection.
Health authorities around the globe have made available various generic guidance for social distancing.
However, as the number of the vaccinated increases, social distancing should reflect the changes in social
behaviours of people with three levels of vaccination (the fully-vaccinated, the partially vaccinated and the
unvaccinated) when they engage each other in daily activities. This new challenge in social distancing is dealt
with as complementary, generic guidance to the existing sets of guidelines published by various authorities
for social distancing. This document is intended to be applicable as long as individuals and organizations
find themselves exposed to or interacting with people with varying vaccination levels.
This document is intended to provide guidance to individuals and organizations and to standardize
guidance from various authorities. Organizations using recommendations of ISO/PAS 45005 for workplace
safety should use this document to refine governance and management essential to the safe operation of the
organizations during vaccinations, and to actively engage with changes in safety requirements.
By familiarizing themselves with this document, individuals can:
— understand revised social distancing practices in places where they find themselves;
— feel secure in places such as public markets where individuals with differing vaccination levels are
present;
— understand the dynamics of the preventive measures during vaccinations;
— plan and adapt social distancing practice when engaged with others in changing disease situations.
By implementing this document, organizations can:
— put in place social distancing policies and safety messages, for both workers and visitors/customers/
patrons, commensurate with vaccination levels in the population;
— establish a framework that facilitates pre-emptive adaptation to evolving disease situations.
The recommendations in the document can be subject to change, depending on the trend of the infectious
disease or other circumstances.

exposure and reduce the transmission of infection

4 Social distancing during pre- and post-vaccinations
One practicing social distancing keeps a safe space between oneself and other people. One may apply it at
home, by reducing travel or avoiding congested gatherings such as theatres, or by shopping online. One
should stay at least 2 m or more from other people in both indoor and crowded outdoor spaces. The rationale
for social distancing is that when people are distanced enough apart, the risk of transmission of the virus is
reduced. To effectively limit further spread of the virus demands a break in the chain of virus transmission.
While vaccination cannot 100 % prevent the transmission of the disease, social distancing can be effective
in reducing the risk during times of outbreak.
5 Source control
5.1 General
A respirator provides filtration of aerosol, particulates and droplets for the user, particularly if fitted. When
the exhaust of the respirator contains a filter, the respirator provides source control. A medical face mask (or
its equivalent) controls the spread of droplets and aerosols from the user who wears the mask and provides
source control. In some cases, the medical face mask also provides a short-term barrier for droplets and
minor filtration of aerosols. Face shields provide moisture control for industrial respirators and masks. The
use of a face shield in combination with a medical face mask or FFP is particularly important when there
remains uncertainty as to whether the wearer has developed immunity. The medical face mask protects
others. FFP2 and FFP3 masks protect oneself and others without valve, and only oneself with valve.
5.2 Proper use of the medical face mask and face shield
— Before use: Disinfect the hands with an alcohol-based handrub for 20 s to 30 s or wash with soap and
water for 40 s to 60 s.
— Placement: Place the mask properly over mouth, nose and cheeks. The mask should fit tightly. Replace the
mask immediately if it becomes soiled or soaked.
— Removal: Remove the mask by touching only the straps and dispose into a dedicated bin.
— After use: Disinfect the hands

6 Social distancing and source control in everyday life
6.1 General
This clause refers to social distancing guidelines set out by relevant authorities of each jurisdiction when
the pandemic breaks out, and which remain in effect until further notice. The post-vaccination guidance
involves adjustments, where applicable, to the general guidance and a response to global vaccination efforts
with the principle that cultural and societal attitudes and differences toward social distancing and source
control should be duly considered when implementing the latter, provided they do not invalidate the public
health objectives;
6.2 Public transit
6.2.1 Public transit passengers
6.2.1.1 General guidance for social distancing
a) Wear a medical face mask or PPE mask in transit (e.g. bus, train, subway, taxi).
b) Maintain as much distance as possible from others in transit.
c) Use non-contact payment options, if possible (credit card, transit card, mobile payment).
d) Practice good hand hygiene – hand wash or hand disinfection if hand wash is not possible.
6.2.1.2 Post-vaccination guidance for social distancing
Passengers should understand that during transit the following conditions can be present.
— Other passengers are infectious and carry the active disease (regardless of vaccination status).
— Other passengers are vaccinated or lack full coverage.
— Other passengers do not wear a medical face mask or PPE mask correctly.
— Other passengers do not adhere to social distancing recommendations.
6.2.2 Public transit authority
6.2.2.1 General guidance for social distancing
The general social distancing recommendations for safety of workers and workplace should be in accordance
with ISO/PAS 45005.
6.2.2.2 Post-vaccination guidance for social distancing
The organization should ensure that flexible controls and management in maintaining social distancing are
in place and adapt its messages and policy in line with potentially relaxed or abandoned social distancing
measures from authorities for those fully vaccinated. The organization should:
a) communicate to all public-facing personnel that they can encounter relaxed or abandoned social
distancing practices among the passengers;
b) ensure that the workers are educat
