Original Abstract of the Article

Main Research Findings

Varicella vaccine is highly effective in preventing varicella, a highly contagious childhood disease, and has been introduced as a single-syringe dose in many countries. 26 , 18 . The vaccine significantly reduces the risk of contracting varicella and is expected to prevent severe complications. 18 . However, like other vaccines, the varicella vaccine carries a risk of side effects. 3 . Side effects from the varicella vaccine are usually mild and temporary, but serious side effects can occur. 14 .

Reasons for Side Effects

The varicella vaccine uses live attenuated varicella virus. 12 . Therefore, some people may experience side effects after vaccination due to the immune response to the virus. 8 . Side effects are thought to be caused by allergic reactions to vaccine components or by an excessive immune response to the virus. 13 .

Common Side Effects

Fever

Fever is a common side effect after varicella vaccination. 13 . This is because the vaccine virus enters the body and the immune system is activated. 13 . Fever usually starts within 1-2 days after vaccination and subsides within a few days. 24 .

Rash

A rash can occur after varicella vaccination. 19 . The rash usually starts within 1-2 weeks after vaccination and subsides within a few days. 12 . The rash can resemble varicella and may be mistaken for it. 23 . However, the rash that develops due to vaccination is less severe than varicella, and serious complications are rare. 12 .

Pain

Pain and swelling at the injection site can occur after varicella vaccination. 24 . This is due to the immune response to the vaccine virus. 13 . Pain and swelling usually subside within a few days. 24 .

Other

In addition to the above, side effects such as fatigue, headache, and muscle aches can occur. 24 . These side effects are usually mild and temporary. 3 .

Side Effects Measures

Fever

If you are concerned about fever, consult a doctor. 13 . Antipyretics may be prescribed if necessary. 24 .

Rash

If you are concerned about a rash, consult a doctor. 19 . Usually no special treatment is required, but if the symptoms are severe, antihistamines or other medications may be prescribed. 12 .

Pain

If you are concerned about pain or swelling, consult a doctor. 24 . Analgesics may be prescribed if necessary. 13 .

Comparison between Studies

Commonalities

Many studies have confirmed that the varicella vaccine is generally safe and effective. 26 , 18 . The varicella vaccine significantly reduces the risk of contracting varicella and is expected to prevent severe complications. 18 . However, like other vaccines, the varicella vaccine carries a risk of side effects. 14 .

Differences

Each study shows different results regarding the incidence and types of side effects of the varicella vaccine. 24 . This is thought to be due to differences in the age and health status of the study subjects, the type of vaccine, and the method of administration. 12 . Differences in research methods and data analysis methods can also lead to differences in results. 13 .

Precautions for Application in Daily Life

The varicella vaccine is a highly effective preventive measure against varicella and has been introduced in many countries. 18 . Vaccination against varicella significantly reduces the risk of contracting varicella and is expected to prevent severe complications. 18 . However, like other vaccines, the varicella vaccine carries a risk of side effects. 3 . Serious side effects can occur, even though side effects from the varicella vaccine are usually mild and temporary. 14 . It is important to consult a doctor and fully understand the risks of side effects before receiving the varicella vaccine. 7 .

Limitations of Current Research

Research on the varicella vaccine is still insufficient. 13 . In particular, the long-term effects of the varicella vaccine are not yet fully understood. 25 . Further research is needed on how the varicella vaccine affects people with specific diseases or treatments. 6 .

Future Research Directions

Future research on the long-term safety and efficacy of the varicella vaccine is required. 10 . Further research is needed on how the varicella vaccine affects people with specific diseases or treatments. 6 . Research on the spread of the varicella vaccine and the acquisition of immunity to varicella is also needed. 20 .

Conclusion

Varicella vaccine is a highly effective preventive measure against varicella and has been introduced in many countries. 18 . Vaccination against varicella significantly reduces the risk of contracting varicella and is expected to prevent severe complications. 18 . However, like other vaccines, the varicella vaccine carries a risk of side effects. 3 . It is important to consult a doctor and fully understand the risks of side effects before receiving the varicella vaccine. 7 .
