Understanding Public Perceptions of Immunisation Using Social Media - Project...UN Global Pulse
This project examined how analysis of social media data could be used to understand public perceptions on immunisation. In collaboration with the Ministry of Development Planning (Bappenas), the Ministry of Health, UNICEF and World Health Organisation (WHO) in Indonesia, Pulse Lab Jakarta filtered tweets for relevant conversations about vaccines and immunisation. Findings included identification of perception trends including concerns around religious issues, disease outbreaks, side effects and the launch of a new vaccine. The results built on Global Pulse’s previous explorations in this field, confirming that real-time information derived from social media conversations could complement existing knowledge of public opinion and lead to faster and more effective response to misinformation, since rumours often spread through social networks.

La INFODEMIA es un neologismo que expresa la sobreinformación que sobre un tema se genera, en algunos casos de forma precisa y en otros no, y que hace difícil a las personas encontrar fuentes fiables para encontrar orientación cuando se necesita. Este gran volumen de información de un tema específico en un corto periodo de tiempo origina una “infoxicación”, es decir, una intoxicación por información. Si esta intoxicación se asocia a una pandemia actual (como la COVID-19) el término infodemia guarda un razonable parecido, teniendo en cuenta que en el “totum revolutum” es campo sembrado para los dimes y diretes, para la rumorología, la información errónea y la manipulación de las noticias con intenciones dudosas. En la era de las nuevas tecnologías de la información y comunicación, de la Web 2.0, 3.0, 4.0… y las que vengan, este fenómeno se amplifica a través de las redes sociales, ese patio de vecinos sin control, extendiéndose más y más rápido que un virus esta información inválida o tóxica: de ahí el término “viralización”.
Si juntamos los efectos del virus SARS-CoV-2 con los efectos de la viralización de las redes sociales, y teniendo en cuenta dos principios conocidos en la comunicación periodística (que una buena noticia no es noticia y que las falacias se difunden más rápido que las verdades), tenemos el cóctel perfecto para crear el caos, el miedo y la COVIDofobia.
Y para que conste la preocupación por la infodemia basta revisar el documento adjunto de la PAHO (Pan American Health Organization), miembro de la Wordl Health Organization, donde se exponen algunos datos de interés para conocer la dimensión de este problema: en el último mes se han volcado 361 millones de vídeos en YouTube en relación con el tema de la COVID-19 y cerca de 20.000 artículos sobre el tema en Google Scholar, así como 550 millones de tweets en un mes que incluían el término COVID-19 o pandemia.
Es crítico disponer del acceso a la información, pero en el momento adecuado y en el formato adecuado. Hoy todo gira sobre lo mismo. Desayunamos, comemos, merendamos, cenamos y hasta dormimos con la misma noticia, visto desde tantas perspectivas y con tantos autoproclamados expertos que ya nos sabemos a qué atenernos. En este ambiente de infodemia, donde campa a sus anchas la prensa amarillista y los que sientan cátedra con la osadía de su desconocimiento, no se pueden aplicar los principios de calma y coherencia tan necesarios para la toma de decisiones.
The epidemic of misinformation about vaccinesCILIP
Dr Pauline Paterson's (Research Fellow and co-director of The Vaccine Confidence Project, London School of Hygiene & Tropical Medicine) presentation at the CILIP 2017 Conference in Manchester #CILIPConf17
Whilst most people vaccinate, some groups or individuals delay or refuse vaccines due to concerns about safety, whether real or perceived, and concerns about information (including mis-information or mis-trust in information). Public concerns about vaccines have occurred around the world, spreading quickly and sometimes leading to vaccine refusals and disease outbreaks.
The presentation will explore case studies on non-vaccination of measles containing vaccine (MCV) and concerns around HPV vaccine globally. This talk will attempt to address the question of how misinformation can undermine public health, exploring selective exposure, selective perception and the issue of multiple realities.
Social media and young people's mental health and wellbeingmResearcher
Social media has revolutionised the way we connect with each other. Platforms such as Facebook, Twitter and Instagram are now used by one in four people worldwide.1 The use of social media has become an integral part of many people’s lives, connecting them with friends, family and strangers from across the globe.
In this presentation, I review how social media and eHealth, in general, can be used to communicate around vaccination. This was part of an expert meeting organized by #Vaccines4Life in Berlin in Jan 2019

Abstract
This project is designed to give a bigger picture of the information so far covered in this course unit. It will provide information from project four which was about social behavior theories and its roots and unit six that concerned about Influenza vaccination in senior citizens 65 and over. It will also give some information from project two which was about the role of assessment in public health. Information about child obesity as a health problem in my community will be provided, and a detailed description of how data will be provided for this health problem assessment. A completed health assessment information using a U.S Census on my community and the evaluation of this information, and the information about who may be affected by this child obesity health evaluation and a plan of action, conclusion and a reference page where information was gathered.

U.S Census data on my County in the State of Maryland
Montgomery County is where I live, located in the state of Maryland. Its population as of 2013 was estimated to be 1,016,677 according to (United States Census Bureau), with a racial breakdown of 62.6% white alone, 18.6% Black and African American alone,0.7% American Indian and Alaskan Natives alone, Asians 14.9%,Native Hawaiian and pacific Islanders 0.1%,Two or more races 3.1%,Hispanic and Latino 18.3%.Those who are not Latinos or Hispanic comprise of 47.0% .Female persons comprise of 51.8% and no information was provided about male. Senior citizens sixty five years and over take up 13.3% .Information for people who are disabled was not provided where as children under five years take up a 6.5% and those under 18 years comprised of 23.6%. (United States Census Bureau)
Influenza Vaccination Health Assessment from Unit 6
Influenza is a deadly virus that attacks the nose, throat and lungs and it can be spread from one person to another if a sick person sneezes or coughs without covering their mouth and the other person inhales it. In United States alone, Influenza is estimated to be responsible for 36,000 deaths, and 110,000 to 200,000 hospitalizations ("Influenza vaccination," 2003). It is a virus that is prevented mainly through immunization. The world at large and the U.S government in particular, has tried their level best to conduct public health campaigns that encourage influenza vaccination but despite all the effort, a number of people do not turn up due to varied reasons. In such helpless situations an assessment can be carried out to help health care advocates find out factors affecting vaccine commitment. A good example of this is from county of Los Angeles where immunization was carried out to people who are 65 and over noted to be one of those at high risk but to their surprise a few categories of people didn’t turn up for immunization. Results from Los Angeles Cou ...

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

4. What is Social Media?
Social media refers to the means of interactions
among people in which they create, share, and
exchange information and ideas in virtual
communities and networks.
5. • Facebook = Friend Builder
• Twitter = Broadcast & Community Builder
• YouTube = Broadcast Content to the World
• Flickr = Photographs to Inspire
• LinkedIn = Professional Connections
• Blogs = Your own online newspaper
• Social Bookmarking (Digg, Stumble) = Sharing
information
6.
7. “The impact of social media on the balance
of power and knowledge between patient
and professional is enormously
significant...”
Disruptive Innovation Report, 2008
8. Implications
• Majority do vaccinate & immunise
themselves & their children
• But many have concerns over safety
• They are seeking information online & via
social media
• How reliable is this information?
10. “A lie can travel halfway
around the world while the
truth is putting on its shoes.”
Mark Twain
11. INSIGHT
A Variety of Factors Influence Behaviour
Personal factors
• Knowledge and awareness – people might not have a good understanding of problem
• Attitudes – view on importance
• Habit – whether or not their other children had it
• Perceived behavioural control – how easy/hard they think it will be
• Emotions – fear of jabs, belief in probability of occurrence
Social factors
• Norms – how does their action fit within their peer groups/community?
Local and wider environment
• Travelling to the GPs
• Pre-existing condition
• Attending with multiple children
• Non-English speakers
12. Ajzen Theory of Planned Behaviour
Behavioural Beliefs
“This act will (will not) have
positive consequences.”
Subjective Norms
“People who are important to
me think I should (not do)
this.”
Perceived Behavioural
Control
“It will be easy (difficult) for me
to do this.”
Behavioural Intention
“I intend (do not intend) to do
this.”
Behaviour
“I actually do
(do not do)
this.”
14. #vaccineswork
The main findings were:
•In all four languages, blogs were the most frequently used channel for posting anti-
vaccine content in social media (86 per cent in Romanian, 85 per cent in Polish, 65 per
cent in Russian and 47 per cent in English).
•Facebook was the second largest channel among all four languages. Twitter was the
second largest channel in Russian, with 24 per cent of total volume.
•While conversations on forums only made up 2 per cent of total conversations, they
accounted for 25 per cent of interactions.
•The data skews towards female audiences on issues such as developmental disabilities
(59 per cent), chemical and toxins (56 per cent), and side effects (54 per cent).
•Men focused on arguments around conspiracy theory (63 per cent) and religious/ethical
beliefs (58 per cent).
•Participants discussing anti-vaccination sentiments are approximately 56 per cent female
and 44 per cent male.

17. 1. Positive: A positive sentiment means the author is likely to get the influenza A (H1N1)
vaccine e.g.
“Off to get swine flu vaccinated before work.”
2. Negative: A negative sentiment means the author is unlikely to get the influenza A
(H1N1) vaccine e.g
“What Can You Do To Resist The U.S. H1N1 "Vaccination" Program? Help Get Word Out.
The H1N1 "Vaccine" Is DIRTY. DontGetIt.”
3. Neutral: No clear sentiment can be detected e.g.
“The Health Department will be offering the seasonal flu vaccine for children 6 months - 19
yrs. of age starting on Monday, Nov. 16.”
4. Irrelevant: The tweet is not clearly about the influenza A(H1N1) vaccine.
“Filipino discovers new vaccine against malaria that 'treats' the mosquitoes, too!”
18. Results
•477,768 collected tweets,
•318,379 were classified as relevant to the influenza A (H1N1) vaccine.
•Of those, 255,828 were classified as neutral
•26,667 as negative,
•35,884 as positive.

Control. PLoS Comput Biol 7(10): e1002199. doi:10.1371/journal.pcbi.1002199
http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002199
20. Main Limitations
1. Observational study - can't exclude other confounding factors (e.g.
vaccine supply)
2. Users of online social media might not be a representative sample of the
population;
3. Messages may be interpreted differently by different users, and
sentiment analysis is not 100% accurate
21. "These results could be used strategically to
develop public-health initiatives," Salathé
explained.
"For example, targeted campaigns could be
designed according to which region needs more
prevention education.
Such data also could be used to predict how many
doses of a vaccine will be required in a particular
area."
