Relationship between Nutritional Status with SARS-COV-2 Antibody Titers after the Coronovac Vaccine Vaccination in SMA Negeri 1 Namorambe Deli Serdang, North Sumatra Province

Introduction

The COVID-19 pandemic caused by the SARS-COV-2 virus has become a global health crisis, resulting in a significant number of cases and deaths worldwide. To combat this pandemic, vaccination efforts have been implemented as a crucial measure to break the chain of disease transmission. The success of vaccination depends on various factors, including the nutritional status of individuals, which can be measured by body mass index (BMI). Nutritional status plays a vital role in the immune system's ability to respond to vaccines, and its impact on the formation of SARS-COV-2 antibodies after vaccination is a topic of interest in the medical community.

Objective

The primary objective of this study is to investigate the relationship between nutritional status and changes in SARS-COV-2 antibody titers after the Coronovac vaccine vaccination in SMA Negeri 1 Namorambe students, Deli Serdang, North Sumatra Province. Understanding the effect of nutritional status on vaccine response is essential in developing effective vaccination strategies.

Method

This study employed a descriptive analytic approach with a cross-sectional method, conducted from August to December 2022. A total of 385 students participated in the study, with primary data collection through a questionnaire and blood sampling from the fingers. The RBD screening examination and anti-S1 antibodies were conducted using the ELISA method in the Integrated Laboratory of the Faculty of Medicine, University of North Sumatra.

Results

The study revealed that there were more female subjects than male subjects, with an average age of 16 years (range 14-19 years) and a standard deviation of 1.03. The history of COVID-19 exposure was reported by 8 people (4.0%), and 2 people (1.0%) had been confirmed infected with Covid-19 from a total of 198 subjects studied. In terms of nutritional status, subjects with normal BMI accounted for 57.1%, while 14.6% were underweight, 13.1% were overweight, and 12.1% and 3.0% had mild to moderate and severe malnutrition, respectively.

Conclusion

The results showed that there were differences in S1 antibody titers in each examination, with an increase in titers over time (p = 0.0001). However, there was no significant relationship between nutritional status based on BMI and changes in SARS-COV-2 antibody titers on H0, H14, H28, and H60 (P> 0.05) examinations. Additionally, an increase in S1 antibody titers in infected groups compared to uninfected groups on the early days (H-0) showed a significant difference (p = 0.001).

Additional Analysis

This study confirms that nutritional status has an important role in general health, but its effect on post-vaccinating antibodies may be more complex than expected. Other factors such as age, genetic, and underlying health conditions may also affect individual immune responses to vaccination. Therefore, it is essential to conduct further research to understand the interaction between nutritional status and vaccine response, as well as to identify the best strategies in the vaccination program that can increase effectiveness for all people.

In the ongoing pandemic context, the results of this study provide valuable insights for health policymakers and vaccination program organizers. By understanding the factors that influence vaccine response, intervention steps can be more effective in protecting the public from COVID-19.

Implications for Health Policy Makers and Vaccination Program Organizers

The findings of this study have significant implications for health policymakers and vaccination program organizers. Understanding the relationship between nutritional status and vaccine response can inform the development of targeted vaccination strategies. By identifying individuals with inadequate nutritional status, healthcare providers can implement interventions to improve their nutritional status, which may enhance their immune response to vaccination. Additionally, the study's results highlight the importance of considering other factors that may influence vaccine response, such as age, genetic, and underlying health conditions.

Future Research Directions

This study highlights the need for further research to understand the interaction between nutritional status and vaccine response. Investigating the impact of nutritional interventions on vaccine response can provide valuable insights. Additionally, exploring the role of other factors that may influence vaccine response, such as age, genetic, and underlying health conditions, can inform the development of more effective vaccination strategies.

Conclusion

In conclusion, this study investigated the relationship between nutritional status and changes in SARS-COV-2 antibody titers after the Coronovac vaccine vaccination in SMA Negeri 1 Namorambe students, Deli Serdang, North Sumatra Province. The results showed that there was no significant relationship between nutritional status based on BMI and changes in SARS-COV-2 antibody titers. However, the study highlights the importance of considering other factors that may influence vaccine response, such as age, genetic, and underlying health conditions. Further research is needed to understand the interaction between nutritional status and vaccine response, as well as to identify the best strategies in the vaccination program that can increase effectiveness for all people.
Frequently Asked Questions (FAQs) about the Relationship between Nutritional Status and SARS-COV-2 Antibody Titers after the Coronovac Vaccine Vaccination

Q: What is the significance of nutritional status in the context of COVID-19 vaccination?

A: Nutritional status plays a vital role in the immune system's ability to respond to vaccines. Adequate nutrition is essential for the production of antibodies, which are proteins that recognize and bind to specific antigens, such as the SARS-COV-2 virus. Malnutrition can impair the immune system's ability to respond to vaccines, leading to reduced antibody production and increased susceptibility to infection.

Q: What is the relationship between nutritional status and SARS-COV-2 antibody titers after vaccination?

A: The study found that there was no significant relationship between nutritional status based on BMI and changes in SARS-COV-2 antibody titers after vaccination. However, the study highlights the importance of considering other factors that may influence vaccine response, such as age, genetic, and underlying health conditions.

Q: What are the implications of this study for health policymakers and vaccination program organizers?

A: The findings of this study have significant implications for health policymakers and vaccination program organizers. Understanding the relationship between nutritional status and vaccine response can inform the development of targeted vaccination strategies. By identifying individuals with inadequate nutritional status, healthcare providers can implement interventions to improve their nutritional status, which may enhance their immune response to vaccination.

Q: What are the limitations of this study?

A: The study has several limitations, including the small sample size and the use of a cross-sectional design. Additionally, the study only measured BMI as an indicator of nutritional status, which may not be a comprehensive measure of nutritional status.

Q: What are the future research directions based on this study?

A: This study highlights the need for further research to understand the interaction between nutritional status and vaccine response. Investigating the impact of nutritional interventions on vaccine response can provide valuable insights. Additionally, exploring the role of other factors that may influence vaccine response, such as age, genetic, and underlying health conditions, can inform the development of more effective vaccination strategies.

Q: What are the practical implications of this study for healthcare providers?

A: The study's findings have practical implications for healthcare providers. Healthcare providers should consider the nutritional status of their patients when developing vaccination strategies. By identifying individuals with inadequate nutritional status, healthcare providers can implement interventions to improve their nutritional status, which may enhance their immune response to vaccination.
