Vaccines Cause Autism?

 


This represents a parent talking to a doctor. This is what vaccine-hesitant parents can do if they are concerned about vaccines.


Introduction

Vaccines are one of the biggest achievements in our medical history. Vaccines protect public health by saving countless lives and preventing many contagious and deadly diseases. However, some parents are hesitant to vaccinate their children due to the belief that vaccines can cause autism, which could make their children more prone to infectious diseases such as the flu. Even though this myth has been disproven, many parents are still hesitant about getting their children vaccinated. The myth that vaccines cause autism is dangerous and could lead to children getting diseases due to not being vaccinated. It is important to influence parents to make the right decisions for their kids, such as getting vaccinated. It is important for the audience to know what is true and false about vaccines and for them to understand the real pros and cons of vaccinations.

Diversity of Beliefs

When researching the belief that vaccines cause autism, researchers wanted to create a study that analyzes how people of different races believed what causes autism. The goal of this research was to help describe and understand what people of different races believe causes autism. They brought in Asian mothers, Hispanic mothers, and white mothers for this study, and they would have the participants answer a questionnaire on what they believe causes autism (Chaidez et al, 2018). Environmental and genetic factors were the most common beliefs that each group had as to what causes autism. Asian mothers were the most common group to believe that there were multiple causes, including vaccines. This highlights that there is a possibility that people of different races have different beliefs on what causes autism (Chaidez., et al, 2018). There needs to be research to confirm these findings to understand parental motivation behind their treatment choices. It is important to understand what parents believe in and to make sure they do not believe misinformation about vaccines, including if they believe it is due to what is in vaccines.

Vaccine Hesitant Parents Vs. Non-Vaccine Hesitant Parents

Vaccine hesitancy has become increasingly common in parents who have children with autism spectrum disorder. Although some stats show that children with autism spectrum disorder are vaccinated, their vaccine reception decreased after turning 2 years old (Goin-Kochel, 2020). Researchers had the goal to analyze factors related to vaccine hesitancy in parents of children with autism spectrum disorder. In this study, they brought in vaccine-hesitant and non-vaccine-hesitant participants, and they took a “Attitudes About Childhood Vaccines questionnaire” (Goin-Kochel, 2020). In this study, researchers wanted to see how parents who have kids with autism spectrum disorder and are vaccine hesitant believe about what caused autism spectrum disorder, compared to how parents who have kids with autism spectrum disorder who are not vaccine hesitant believe. It was revealed that 64 percent of vaccine-hesitant parents believed that autism spectrum disorder was caused by vaccines and concern for possible toxins that might be in them; meanwhile, only 3 percent of parents who were not vaccine-hesitant believed that it was caused due to vaccines (Goin-Kochel, 2020). Although 74 percent of vaccine-hesitant parents also believed that genetics can be a cause, which is correct, it is still concerning that most of them also believed that vaccines can be a cause as well. This just emphasizes the point of how harmful the myth that vaccines cause autism can be.

Vaccine Hesitancy Prevention

Vaccines are one of the most effective medical accomplishments in our medical history. Vaccinations have saved millions of lives from many deadly diseases. Sadly, vaccine hesitation has been recognized as one of the biggest health problems that we face today. This can be dangerous since COVID-19 can be very infectious to children, and COVID-19 can seriously harm children (Chen et al., 2024). The goal of this research was to analyze the effects of social support and health literacy on vaccine hesitancy in the first and second doses of vaccines. The cross-sectional study brought in parents with young children, and there were around thousands of children in this study, with 35 percent of parents being vaccine-hesitant (Chen et al., 2024). The survey would collect stats such as getting information on sociodemographic attributes, health literacy, social support, and vaccine-hesitancy in parents with the use of questionnaires (Chen et al., 2024). Parental hesitancy rate for the first dose of the COVID19 vaccine was at 69 percent and 33 percent for the second dose. It was shown that vaccine hesitancy was linked to parental level education, allergies, decision making, comprehension ability, and social support (Chen et al., 2024). These were all factors that caused vaccine hesitancy. This study provides insight for future prevention of vaccine hesitancy and provides information on vaccines to prevent parents from putting their children in danger due to vaccine hesitancy.

Link Between Vaccines and Autism?

In another study, researchers wanted to prove there was no link between vaccines and autism. They would use a cohort study to analyze thousands of children and would analyze them over time to see whether vaccines were causing or worsening their autism. Records were used to find a connection between MMR vaccination, autism diagnoses, other childhood vaccines, family history of autism, and autism risk factors in children (Hviid et al., 2019). During the years of analyzing these children, around 6,000 of them were diagnosed with autism spectrum disorder. They compared vaccinated children and unvaccinated children, and they did not find a link between vaccines causing autism, nor did not increase the risk of getting autism spectrum disorder after getting vaccinated (Hviid et al., 2019). Overall, this study proves that vaccines such as the MMR vaccine do not raise the possibility of autism and do not cause autism spectrum disorder. This is helpful for parents who are concerned about getting their kids vaccinated because, with this study, parents can now feel confident that vaccines will not cause autism or increase the risk of getting autism.

Can Vaccines Worsen Autism?

Despite that the myth of how vaccines cause autism was debunked, there is still a high belief in this myth that has led to the low rate of vaccines. This is most likely due to concerns about what is in the vaccines and not trusting medical professionals. This can be very harmful since, without vaccines, you are more prone to diseases such as measles, mumps, and rubella. In this study, researchers wanted to see if MMR vaccines were causing or increasing autism, using children from the U.S with older siblings who have or do not have autism spectrum disorder (Jain et al., 2015). They would do a cohort study to analyze the children over time to see if the MMR vaccine was increasing or causing them to have autism spectrum disorder. After analyzing the children with and without autism spectrum disorder after receiving the MMR vaccine, they found no relationship between the MMR vaccine and a cause or increased risk of autism spectrum disorder (Jain et al., 2015). This study highlights that parents can vaccinate their children without worrying that vaccines cause or increase autism spectrum disorder.

Conclusion

Due to the harmful myth that vaccines cause autism, people of different races believe in different and multiple causes of autism. Although many vaccine-hesitant parents with children who have autism spectrum disorder believe that genetics can be a reason, which is correct, many of them also believe that the vaccines can cause concerning autism because this myth has been disproven, and they are putting their children in danger of being more prone to diseases. Vaccine hesitancy was linked to parental level education, allergies, decision making, comprehension ability, and social support, and there needs to be an intervention to inform parents about vaccines. After analyzing children with and without autism spectrum, it showed proof that vaccines do not cause or increase the risk of autism spectrum disorder. With this blog, I hope it show parents the seriousness of vaccine hesitancy and that it shows that vaccines do not cause autism. Vaccines are one of the greatest medical achievements in history, and we need to use these vaccines to keep children safe from fatal diseases.
