Original Abstract of the Article

Main Research Findings

Numerous studies have been conducted on polio vaccines, leading to a range of discoveries. 11 revealed that many vaccines, including polio vaccines, utilize live attenuated or inactivated bacteria and viruses. These stimulate the immune system and are effective in preventing diseases, but they can also cause side effects ranging from mild to severe. 16 states that the first polio vaccine was introduced in 1955, followed by the oral vaccine. Polio vaccines have significantly reduced the incidence of polio in developed countries. However, polio remains a serious threat in developing countries. 18 conducted a clinical evaluation of a new DPT-polio vaccine (DPTP) developed in France. This vaccine was randomly assigned to three groups of 320 infants aged 3 to 24 months: a group that received two doses of DPTP, a group that received two doses of DPT and poliovirus vaccine (IPV) at separate sites, and a group that received two doses of DPT and oral poliovirus vaccine (OPV). As a result, the DPTP group achieved antibody titers of 100%, 100%, and 92% for pertussis, diphtheria, and tetanus, respectively. Additionally, the group that received IPV simultaneously or in combination with DPT had a 100% seroconversion rate to poliovirus antigens, compared to 49% to 77% in the group that received OPV. These studies suggest that polio vaccines are safe and effective, but there are various side effect risks.

Reasons for Side Effects

Polio vaccine side effects are thought to be caused by a complex interplay of various factors, including the vaccine's components, administration methods, and individual susceptibility. 11 mentions the possibility of live attenuated viruses reverting to a pathogenic form as a potential side effect of polio vaccines. 14 reports a case of trismus associated with tetanus immunization. Additionally, 3 suggests that the novel oral polio vaccine (nOPV2) may not be immediately trusted by communities and health workers due to its novelty, potential side effects, and introduction under an Emergency Use Listing (EUL).

Common Side Effects

Fever

Fever may occur after receiving a polio vaccine. 14 lists fever following tetanus immunization as a common side effect.

Pain and Swelling at the Injection Site

Pain and swelling may occur at the injection site after receiving a polio vaccine. 14 lists pain and swelling at the injection site after tetanus immunization as common side effects. 2 suggests that aluminum-containing vaccines can cause muscle damage and inflammation. However, this damage usually recovers within a month of vaccination.

Other Side Effects

In addition to the side effects mentioned above, polio vaccines may cause symptoms such as nausea, vomiting, diarrhea, headache, and fatigue. 10 investigated the vaccination status of children admitted to tertiary care hospitals in India and found that poor health conditions in children and low educational levels of parents were factors contributing to partial or incomplete vaccination. Additionally, 1 states that in areas of Pakistan with low polio vaccine coverage, concerns and distrust about vaccine safety are cited as reasons for vaccine refusal. Furthermore, 19 points out that although the incidence of paralysis associated with the vaccine is extremely low, healthcare providers and vaccine manufacturers may be liable for such adverse effects in some states.

Side Effect Countermeasures

Countermeasures for Fever

If you are concerned about fever, it is important to consult a doctor and get proper instructions. When using over-the-counter fever reducers, follow the directions and instructions provided by the doctor.

Countermeasures for Pain and Swelling at the Injection Site

If you are concerned about pain and swelling at the injection site, applying cold compresses may alleviate the pain. Keep the area clean and avoid excessive movement. If symptoms do not improve, consult a doctor.

Countermeasures for Other Side Effects

If you are concerned about other side effects, consult a doctor and seek proper instructions. Depending on the situation, you may receive advice on medication, lifestyle changes, and other measures.

Comparison between Studies

Common Points between Studies

Many studies have shown that polio vaccines are safe and effective, while acknowledging various side effect risks. It is also a common finding that various factors, including vaccine components, administration methods, and individual susceptibility, can influence side effects.

Differences between Studies

Studies on polio vaccine side effects vary in terms of target age groups, vaccine types, and research methods, leading to different results. 18 found that the DPTP group achieved antibody titers of 100%, 100%, and 92% for pertussis, diphtheria, and tetanus, respectively. On the other hand, 8 suggests that the quadrivalent meningococcal serogroups A, C, W, and Y conjugate vaccine (MenACWY-CRM) is safe when administered concurrently with routine vaccinations in infants. 5 compared six vaccination schedules with different sequential doses of inactivated poliovirus vaccine (IPV), tOPV, or bOPV to assess the immunogenicity and safety profile of the bivalent oral poliovirus vaccine (bOPV), suggesting that bOPV is safe and immunogenic. These research findings suggest that while polio vaccines are safe and effective, the immune responses and side effects elicited by vaccines can vary depending on the specific vaccine and vaccination schedule.

Points to Note for Application in Daily Life

Research findings on polio vaccines help deepen our understanding of polio prevention and treatment. However, since polio vaccine side effects can vary from person to person, it is crucial to consult a doctor before receiving the vaccine to determine the appropriate vaccine for your body type and health condition. After vaccination, be mindful of changes in your health and consult a doctor immediately if you experience any abnormalities.

Current Research Limitations

Research on polio vaccines is still ongoing and not yet exhaustive. Further research is needed, particularly on the long-term effects of vaccines and their impact on individuals with specific constitutions. Additionally, data collection on polio vaccine side effects is still inadequate. More comprehensive data collection will allow for more effective side effect prevention and management.

Future Research Directions

Future research on polio vaccine side effects should focus on investigating the long-term effects of vaccines and their impact on individuals with specific constitutions. It is also important to uncover the causes and mechanisms of side effects and develop new vaccines and administration methods to reduce them. Moreover, it is essential to strengthen data collection on polio vaccine side effects and enhance information disclosure regarding side effects.

Conclusion

Polio vaccines are highly effective in preventing polio but carry the risk of side effects. It is crucial to consult a doctor before receiving the vaccine to determine the appropriate vaccine for your body type and health condition. After vaccination, be mindful of changes in your health and consult a doctor immediately if you experience any abnormalities.
