Influenza viruses are important human respiratory pathogens
that can cause seasonal influenza epidemics and out-of-season
sporadic cases and outbreaks. Influenza occurs globally with an
annual attack rate estimated at 5%-10% in adults and 20%-30%
in children [1]. Yet, a message on Internet during winter peak of
2018 influenza has provoked widespread discussion in Hong Kong
regarding vaccination [2,3].
Introduction
Internet exposure can significantly affect patient perception of
vaccination. Viewing typical vaccine-critical websites for only 5-10
minutes increases the perception of risk regarding vaccinations
and decreases the perception of risk regarding the omission of vac-
cinations as compared to visiting a control site [13].
The voice message on internet raised several questions regard-
ing influenza vaccination [4]:
Content of the Internet voice message
The exposure to information including from Internet may be
associated with negative effect on public’s perception towards
healthcare programmes, such as vaccination. General public ob-
jects to vaccination due to fear of adverse effect, perception of in-
sufficient test, ‘public panicking’, necessity, and lack of information
of vaccine [14].
From February 07, 2018 [2,3], a 5-minute voice message has ap-
peared on Internet forum. It is released by a Hong Kong celebrity
in private discussion and uploaded by other people on a parents’
forum which then spread through Internet, in which the content
mainly focuses on the harmful ingredients like mercury and alumi-
num, bacteria existence may cause iatrogenic disease, mutation of
bacteria due to human and animal DNA mixing, high risk and low
effectiveness of vaccination [4].
Widespread of the message through Internet led to intense
public discussion regarding the issue, and various healthcare pro-
fessionals have responded to the event in announcement [5] and
news [6-11], including government official [5], legislator [6,7], and
professor [8-11]. The vigorous debate among various groups trans-
formed the issue into an event of societal level.
1. The vaccine contains mercury and aluminum as part of the
composition
2. Scientists “gamble” about the type of influenza virus by
chance
3. The vaccine is produced by injecting bacteria into chicken’s
body and then the eggs contain the bacteria, such mixture of
human and animal DNA cause mutation
4. The bacteria become “super-bacteria” after the injection
into human body and cause iatrogenic illness of a healthy
person.
These claims have raised vigorous public concern and discus-
sion, which may lead to discouragement of vaccination by the pub-
lic.
A group of medical professionals responded quickly after the
spread of voice message on Internet.
Response from various medical professionals
A group of medical professionals stated on Internet that all
Hong Kong independently packaged single-dose seasonal influenza
vaccines does not contain thimerosal [12].
Composition
A statement from the Department of Health claimed that this
season’s vaccine strains closely match the influenza viruses that are
circulating this winter influenza season in Hong Kong [5].
Effectiveness of vaccine
A news article mentioning the opinion of Professor YUEN of the
University of Hong Kong state that the vaccine is injected to the egg
and the production is based on the embryo of chicken. The virus is
then killed and followed by isolation and purification of antigens.
Thus most of the vaccines are purified. The amount of remaining
egg white is negligible and is harmless [10,11].
The animal-based vaccine would not cause adverse events to
host
Patients’ perception is strongly affected by Internet informa-
tion
Mistrust towards the authorities (government, public health
professionals) also plays a role in vaccine hesitancy, as parents
who did not fully vaccinate their children held feelings of distrust
towards government [15].

Vaccination perception is negatively affected by exposure to In-
ternet information, as parents and general public tend to be nega-
tively influenced by Internet opinion regarding vaccination safety,
and current initiatives aiming to reach and influence parents’ deci-
sion to vaccinate have not adequately abated the influence of the
online anti-vaccination movement [16].
Health education and promotion about vaccination
Individual level
Parents’ decision regarding vaccination mainly depends on phy-
sician recommendation, effectiveness and risk of temporary side
effects (presence of mercury-containing preservative) [17]. Diffu-
sion of negative information online and lack of knowledge about
vaccines were identified as the key causes of vaccine hesitancy
[18]. A study suggested that for individual-based health education,
a medical consultation regarding information about influenza vac-
cination and a clear recommendation by the presenting physician
is a strong factor on accepting vaccination [19].
At the primary care practitioner level, parental education on
influenza vaccine regarding efficacy and safety may also help to
improve pediatric vaccination rates. General public often weighs
vaccine effectiveness heavily [17], and physicians should provide
sufficient information to general public before making decision on
vaccination. For example, physicians should state there are varying
effectiveness of vaccinations season in various countries, and effec-
tiveness of vaccine against influenza A and B in 2017-2018 season
is reported to be 36% in US [20].
Medical professionals should well-educate public regarding the
use of preservatives in vaccine. Physicians may inform general pub-
lic the existence of thimerosal, and that it is very unlikely to cause
adverse outcomes [21]. Also, the peak body mercury burdens af-
ter exposure to thimerosal-containing vaccines did not exceed the
maximum burden of mercury even in underweight infants [22].
Physicians may also educate general public on egg allergy in
view of vaccine hesitancy. Before vaccination, relevant medical his-
tory of allergy should be well-obtained, and potential allergic risk
should be well-explained. Egg-related severe allergic reaction is
extremely rare, as anaphylaxis after vaccination is rare in all age
groups [23]. A study stated that egg-based trivalent influenza vac-
cine can be safely administered even in children with severe egg
allergy [24].
Community based
The event provides a good example for the tremendous effect
of mass media, such as Internet, on general public perception and
hence affect population health in terms of healthcare coverage.
As general public opinion on Internet may produce great effect
on public perception towards vaccination, there might be a need
of public health intervention through effective ways using Internet
and online resources [16].
General public, especially adolescents, does not show enough
sophistication of appraisal skills to correctly judge on information
from Internet sources, and some even does not search on Internet
to verify information. Public tends to be affected by first-impres-
sion of information on Internet [25], tends to judge information
based on instinctive response [25], as well as tends to believe in
majority of websites if in doubt, instead of critically appraising the
material [26]. Mcpherson., et al. also stated that many people re-
quire greater skills for assessing the quality and trustworthiness
of online health information [26].
It is thus encouraged for the public to learn to verify Internet
information through database search in order to acquire better
searching and critical appraisal skills, as the establishment of ac-
curate and authoritative online healthcare database may enhance
general public medical knowledge [27]. It is also suggested that
healthcare professionals should consider to promote population
health programmes through Internet. Parents nowadays are more
affected by information from Web sites and electronic means of
communication [28].
Conclusion
The event is thus a good reminder for authorities, including
government and medical professionals, to notice the importance
and powerfulness of Internet information spread among general
public, which may have tremendous effect on public perception
and decision-making regarding healthcare programmes includ-
ing seasonal influenza vaccination. We suggest there is a need to
strengthen public health education through Internet materials, as
well as guidance to appraise information, and the education mate-
rial should focus on vaccine effectiveness and clarifying the misun-
derstandings of vaccination.
