The COVID pandemic has disrupted many areas of routine healthcare together with, importantly, childhood vaccination.

The pandemic noticed ranges of important childhood immunisations decline in more than 100 countries around the globe, resulting in outbreaks of infectious diseases comparable to yellow fever, cholera, diphtheria and polio.

There are many reasons for this, together with points with provide, restricted entry to companies, and in some areas, elements unrelated to the pandemic comparable to battle. But one contributor that’s necessary to recognise and tackle is vaccine hesitancy.

In 2019, the World Health Organization (WHO) recognized vaccine hesitancy as one in every of its prime ten threats to global health. It seems this risk has solely elevated because the COVID pandemic.

An ideal storm for infectious ailments

While COVID has had vital penalties for world vaccination charges, there are indicators that, in some international locations and for some ailments, there was a longer-standing stalling and even decline in vaccine protection.

In England, for instance, childhood vaccination protection usually plateaued from round 2011 and declined from round 2014.

Rates of many infectious ailments declined on the top of the pandemic as a consequence of widespread social distancing measures, however circumstances have since began to extend. For instance, the variety of international locations with vital measles outbreaks rose by 50% between 2020–21 and 2022–23. Cases have additionally lately occurred in some high-income countries with traditionally good vaccine protection.

Measles, which may be deadly for unvaccinated children, is extremely contagious and spreads in a short time. It’s typically thought to be the “canary in the coalmine” – if measles circumstances are spreading, this can be a warning that different illness outbreaks may spring up the place there are gaps in vaccination protection.

The mixture of reduced vaccine coverage, overstretched healthcare systems, and the return to pre-pandemic levels of social contact have created an ideal storm for infectious illness charges to rise. Growing vaccine hesitancy is barely more likely to make this difficulty worse.

A recent report from Unicef reveals that confidence within the significance of vaccines for kids is decrease now than earlier than the pandemic in lots of international locations.

And whereas total confidence has declined, some drops have been seismic. In South Africa and Japan, for instance, the proportion of individuals assured within the significance of childhood vaccines dropped by roughly one-third throughout the pandemic.

Even in international locations like the US the place total confidence within the significance of childhood vaccines stays comparatively excessive, considerations over potential side-effects have grown over the previous two-to-three years.

What drives vaccine hesitancy?

One of the main factors resulting in hesitancy in the direction of COVID vaccines particularly has been concern that the vaccines have been developed too rapidly. However, we all know that COVID vaccines are safe and effective.

In our research on attitudes to COVID vaccines, my colleagues and I discovered that considerations over side-effects, mistrust in authorities and a perception in conspiracy theories all elevated hesitancy. And hesitancy round COVID photographs may additionally result in hesitancy “spillover” for other vaccines.

The Unicef report equally notes that diminished belief in authorities, in addition to the proliferation of misinformation and conspiracy theories on social media, are rising challenges to public perceptions of vaccines.

Misinformation is a vector of illness

Over the course of the pandemic, we’ve seen widespread misinformation round the safety of COVID vaccines, which has unsurprisingly been linked to reduced confidence in the vaccines.

The downside with misinformation is how intractible it may be. Myths, conspiracies or falsehoods about vaccines may be laborious to shake. For instance, the notorious 1998 research falsely linking MMR vaccines to autism – lengthy since retracted and completely debunked – nonetheless has unfavorable results 25 years later. This may be seen within the conspiracy theories espoused by prominent anti-vax voices in high-income international locations just like the US, and in hesitancy felt by ordinary parents in a lot much less rich international locations comparable to Kyrgyzstan.

How can we enhance vaccine confidence?

Vaccinations forestall 4–5 million deaths a 12 months. But in line with the WHO, an additional 1.5 million deaths might be averted if world protection of vaccinations improved. Reducing vaccine hesitancy is one a part of the answer.

For instance, a study from Japan predicted that vaccine hesitancy in relation to the HPV vaccine between 2013 and 2019 may result in roughly 5,000 deaths from cervical most cancers.

To tackle vaccine hesitancy, we have to tackle the root causes. We can look to the “three Cs model”, which suggests we have to maximise comfort (making vaccines straightforward to entry) and minimise complacency by adequately speaking the dangers of ailments. The third “C” is confidence.

Crucially, to extend confidence, we have to fight vaccine hesitancy brought on by misinformation. One manner to do that is thru “inoculation” or “prebunking”, the place individuals are uncovered to small quantities of false data – for instance, in online games or social media videos. This helps bolster their “immunity” to misinformation by enhancing their critical assessment skills.

Another manner is to make use of social media to fight misinformation by investing within the promotion of correct data. Organisations such because the WHO and Unicef will play a key function in constructing confidence globally.

In quick, alongside efforts to catch kids up with vaccine doses missed throughout the pandemic, we additionally must deal with misinformation. Otherwise, vaccine hesitancy will stay one of many best threats to world well being for years to return.
