What is the issue?
- There is a spread of misinformation from an UN-based platform about vaccination recently.
- This unchallenged spread could affect the global vaccination programme.
What is the global perspective?
- WHO - In January 2019, the World Health Organization (WHO) listed vaccine hesitancy as among the top 10 threats to global health this year.
- Vaccine Hesitancy is defined as a reluctance or refusal to vaccinate despite the availability of vaccines.
- According to WHO, vaccination prevents between 2-3 million deaths each year, a figure that will rise by another 1.5 million if vaccine coverage improves.
- Survey - Yet, a survey of over 1,40,000 people from 140 countries has revealed the striking difference in how people trust vaccines.
- At 95%, people from South Asia trusted vaccines followed by eastern Africa at 92%.
- Western and Eastern Europe brought up the rear with just 59% and 52%, respectively.
- The repercussions of vaccine hesitancy are now playing out globally - as, on October 10, 2019, nearly 4,24,000 children have confirmed measles, as against a figure of 1,73,000 in the whole of 2018.
What is the Indian perspective?
- Vaccine hesitancy has been a concern in India.
- 2018 study - Points out that the vaccine hesitancy continues to be a huge challenge for India.
- The study found nearly a quarter of parents did not vaccinate their children out of a fear of adverse events.
- This was in 121 high priority districts chosen by the Health Ministry for intensified immunisation drive to increase vaccine coverage.
- In 2016, Muslim communities in two districts in north Kerala reported low uptake of diphtheria vaccine.
- Reason - Propaganda that the vaccine may contain microbes, chemicals and animal-derived products which is forbidden by Islamic law.
- In 2017, when the measles-rubella vaccine was introduced, Tamil Nadu and Karnataka, which have traditionally seen high vaccine acceptance, witnessed low uptake.
- Reason - Fear of adverse effects from vaccination.
What was the misleading tweet?
- Against this background, a self-styled yogi Jaggi Vasudev tweeted a message on side-effects or negative impacts of vaccinations.
- This dangerous sweeping statement will give anti-vaxxers the impetus and ammunition to scare parents from vaccinating their children.
- Stirring fear in people by falsely blaming vaccines for unrelated diseases is the bedrock of the anti-vaccination movement across the globe.
- Even today, the message of a 1998 discredited study which linked the measles, mumps, and rubella (MMR) vaccine with autism, is used in spreading vaccine doubts and conspiracy theories.
- Besides the dangerous message, it is difficult to fathom the sudden provocation for the tweet.
What happened at the UN?
- There was a conversation between Jaggi Vasudev and Dr. Soumya Swaminathan (Chief Scientist, WHO) that was held at the United Nations General Assembly on June 27, 2019.
- During the conversation with Dr. Swaminathan, he is seen advocating vaccination and spelling out the gains India made by preventing children from becoming crippled through oral polio vaccination.
- But soon he veers off track and ends up spreading dangerous misinformation about influenza or flu.
- This might turn out to be the most dangerous piece of misinformation to have ever been said from the hallowed platform of the UN.
- Unfortunately, the patently wrong message went unchallenged, giving it a ring of truth.
- The incorrect message is now posted on the Isha website, increasing the chances of more people being misled.
- The blithe comment about flu without any evidence is in stark contrast to the seriousness with which WHO and the Atlanta-based Centers for Disease Control and Prevention (CDC) treat it.
- The CDC website says that the flu illness is more dangerous than the common cold for children, especially for those less than 5 years of age.
- Children older than 6 months and younger than 5 years belong to the high-risk category, the reason why the CDC recommends vaccination against flu each year.
- WHO recognises children below 5 years as a high-risk group and recommends vaccination each year.
What is a good defence?
- It is already proven that vaccination offers the best defence against flu and its potentially serious consequences, reduces flu illnesses, hospitalisations and even deaths.
- Despite H1N1 (swine flu) becoming a seasonal flu virus strain in India, the uptake of flu vaccine in India is poor - the reason why thousands of cases and deaths get reported each year.
- As on 3rd November 2019, there have been 28,109 H1N1 influenza cases and 1,203 deaths this year in India.
- The number of H1N1 influenza cases (42,592) and deaths (2,991) in India peaked in 2015.
- Despite its varying effectiveness in different seasons, several studies have shown that the flu vaccination can reduce the risk of flu illness by 40-60% when there is a good match between the vaccine’s strains and the circulating virus.
- A study in 2017 that looked at flu seasons between 2010 and 2014 found that vaccination reduced flu-associated deaths by 65% among healthy children.
- The vaccine can also prevent hospitalisation; reduce the severity of illness and prevent life-threatening complications in children.
- As per WHO’s recommendation, since September 2018, the protection offered by flu vaccines has been widened with the availability of vaccines containing four strains instead of three.
