While Malaysia hopes to achieve herd immunity against Covid-19 by February 2022, there remains hesitancy to receiving the vaccines against the SARS-CoV-2 virus.
In the last few months, there has been a rise in those registering for the vaccine, with recent figures at the time of writing indicating that approximately one-third of the population have done so.
However, revised estimates have indicated that herd immunity will only be achieved when 70-85% of the population are fully vaccinated.
Malaysia is aiming for 80% of its population to receive the vaccine.
Therefore, despite the recent increase in vaccine registration, Malaysia remains a long way from its target.
This is alarming given the recent spike in the numbers of new Covid-19 cases and deaths worldwide.
One only needs to look at the devastating and horrific situation in India and Brazil to be reminded of the dangers of this disease.
With hospitals being overloaded due to a shortage of beds and ventilators, countries such as Vietnam, Japan and Malaysia are showing trends that could lead to a severe public health crisis.
The invisibility of the threat is something that is perhaps difficult for a large percentage of the world’s population to grasp.
It could be argued that this is because most major disease epidemics have been eradicated, therefore, we have little firsthand experience of the devastation such infectious diseases can cause.
This is not because the threat disappeared on its own, but rather, through the effectiveness of modern science and the development of vaccines.
Due to the low confidence of the public in the available Covid-19 vaccines, it is important to remember how vaccines have helped us tackle public health crises in the past.
Polio, which has affected humanity throughout recorded history, leads to varying degrees of paralysis.
By 1955, the first successful polio vaccine was declared effective, and more importantly, safe for mass distribution to the public.
Families then were queueing in the streets in the hope of receiving the vaccine to shield themselves against the polio virus – a stark difference to the reception of the Covid-19 vaccines, with many declining the vaccine or skipping their vaccination appointment.
There can be a number of reasons why the population remains hesitant to the Covid-19 vaccines, e.g. distrust in organisations and institutions, staunch belief in personal freedom and autonomy, and concerns about vaccine safety and efficacy.
These reasons are amplified by social networking sites (SNS) and cross-platform instant messaging services (IMS).
These tools have emerged as powerful health communication platforms for the distribution of information.
For example, during the early period of the Covid-19 pandemic, they were awash with information, narratives of lived experiences, and citizen advice from a range of sources.
Soon after, however, these platforms became filled with fake Covid-19 news, which continue to propagate now.
A recent example of this was a viral message on SNS and IMS indicating that French virologist and Nobel laureate Dr Luc Montagnier had claimed that “all vaccinated people will die within two years”.
Since then, India’s Press Information Bureau has confirmed that the claims are false, with eminent vaccine experts also providing evidence against this statement.
However, the status of a Nobel Prize winner gave emphasis to the erroneous message, even if these were not his words.
Similar to the status of actors being used in the distribution of misinformation, technological advancements make fake news seem legitimate to the extent that it is sometimes hard to tell real Covid-19 news from the fake.
The development of technology has always been followed by misinformation and conspiracy theories, e.g. the moon landings and the development of the television.
This is similar to what we are seeing with Covid-19 and the vaccine programmes.
Misinformation has saturated popular platforms such as WhatsApp and Twitter, where credibility is given to the content once it is spread within trusted groups, such as friends or family.
This can lead to many not registering for the vaccines as they believe that they are receiving correct information.
Much of the misinformation is spread by organised anti-vaccination movements, which have been around since the first vaccine for smallpox in the 1800s.
Anti-vaccination protestors argue against medical science in favour of their own interpretations, such as the Montagnier example above.
There can be numerous explanations why these anti-vaccination groups exist, with one being financial.
There is great financial benefit through fear of the situation we are in, with many making a huge profit from selling products like natural supplements, and social media earnings.
However, the spread of dangerous misinformation, such as natural remedies as an alternative to the vaccine, can destabilise vaccine programmes and lead to significant public harm.
Anti-vaccination groups do not need to prove that they are correct in their beliefs, they only need to cause doubt.
The fear from this doubt of the public is natural, as at the end of the day we just want what is best for ourselves and our family.
However, such doubt can have a lasting effect in the minds of people, despite the misinformation being debunked, and can be devastating as a result.
In 1998, Andrew Wakefield, then a doctor, speculated a possible relationship between autism and the measles, mumps and rubella (MMR) vaccine.
The results of Wakefield’s work were debunked due to lack of evidence supporting his findings; however, MMR vaccination rates began to drop soon after due to fear and confusion over the safety of the vaccine.
Following this, measles outbreaks have recurred around the world.
For originating one of the most serious medical frauds in history, Wakefield was removed from the medical register in the United Kingdom and may no longer practice medicine.
However, the effect of the misinformation remains, with many people still believing in the possible link between the MMR vaccine and autism.
Similarly, with the Covid-19 vaccines, there is significant risk that misinformation across SNS and IMS may lead to lasting negative attitudes and/or mistrust in the vaccine process.
Make no mistake, we are at war with this invisible enemy.
This is a war that has no borders or rules, and is indiscriminate in its attack, targeting everyone regardless of ethnicity, gender or socioeconomic group.
It endangers our lives, our loved ones, our community and our way of life.
Our only tactics so far have been defensive, with physical distancing, the use of personal protective equipment (PPE) and frequent handwashing or sanitising.
However, we finally have a weapon to reduce further devastation.
Achieving herd immunity would allow us to vastly increase the protection around ourselves and our family.
It is essential that we listen to real vaccine information from reputable medical scientists and follow the national guidelines.Dr David Barron is a psychologist and deputy director of the Perdana University Centre for Psychological Medicine.
