The Side Effects of Vaccines - How High is the Risk?
Kurzgesagt – In a Nutshell・2 minutes read
Vaccines work by tricking the body into producing memory cells and becoming immune to diseases, offering protection against dangerous diseases for years. The debate on vaccines is imbalanced, with pro-vaccine arguments relying on studies and statistics, while anti-vaccine arguments often lead to harmful consequences like increased child mortality and disease resurgence.
Insights
- Vaccines work by tricking the body into producing memory cells and becoming immune to diseases, offering long-term protection against dangerous illnesses by stimulating a natural immune response.
- The debate on vaccines is imbalanced, with pro-vaccine arguments supported by studies and statistics, while anti-vaccine arguments often stem from gut feelings, anecdotes, and misinformation, leading to harmful consequences like increased child mortality and disease resurgence.

Vaccine Safety and Herd Immunity: A Summary
- Encephalitis is the most serious side effect of vaccination, with around 120 out of 10 million vaccinated children experiencing somewhat serious side effects.
- Good medical treatment in developed regions ensures that almost all children with serious side effects will recover.
- The connection between autism and vaccines has been disproven numerous times, with further reading and videos available for reference.
- It is challenging to determine if any of the 10 million vaccinated children would die, with only a few documented cases of lethal vaccine side effects among hundreds of millions of vaccinated children since 1971.
- Measles pose a significantly higher risk than vaccine side effects, with 110,000 deaths worldwide in 2017 and 300 children statistically dying from measles daily.
- Vaccines can be compared to seatbelts, with rare accidents occurring but overall safety being paramount.
- Herd immunity is crucial for protecting unvaccinated children, requiring 95% vaccination coverage to prevent disease spread.
- The debate on vaccines is imbalanced, with pro-vaccine arguments based on studies and statistics while anti-vaccine arguments often rely on gut feelings, anecdotes, and misinformation, leading to harmful consequences like increased child mortality and disease resurgence.
