Chickenpox vaccine side effects

Because children are still in the developmental stage and their immunity is relatively low, people will choose to vaccinate them to prevent them from being infected by germs. In ancient times, chickenpox was considered a very scary disease and was difficult to treat. Now that medical technology is more advanced, people have developed a way to prevent and treat chickenpox, through vaccination. However, there are still risks in getting this vaccine because the chickenpox vaccine has side effects.

There are some people who are contraindicated for the chickenpox vaccine. If they accidentally get the vaccine, they may experience mild discomfort or even shock. What are the dangers? However, what are the side effects of the chickenpox vaccine? Let us explore the side effects of the chickenpox vaccine together.

Effectiveness of varicella vaccine: Large-scale clinical studies have shown that the serum antibody conversion rate of healthy children after one dose of varicella attenuated vaccine can reach 98.6%, 90% for leukemia patients, and 80% for immunodeficiency patients. Therefore, it is recommended that immunodeficiency patients receive two doses to obtain lasting protection. Vaccination within 72 hours of exposure to natural varicella infection can still provide some protection.

How to get the varicella vaccine:

Usage and dosage: Disinfect the attachment of the deltoid muscle on the outer side of the upper arm with disinfectant, and after it dries, inject 0.5 ml of the vaccine subcutaneously per person.

Things to note about the varicella vaccine:

1. After vaccination, take a proper rest, drink plenty of water, keep warm, and avoid strenuous activities.

2. After vaccination, stay at the vaccination unit for 30 minutes and leave after observing that there is no abnormality.

Side effects and adverse reactions of varicella vaccine:

1. If redness, swelling, or hard scabs appear at the injection site, apply hot compresses 3 to 5 times a day until the swelling subsides.

2. The attenuated varicella vaccine has a very low overall reactogenicity in all age groups, and injection site reactions are usually mild and temporary. Some individuals may experience pain at the injection site, and occasionally fever accompanied by a transient rash, which usually does not exceed 3 days.

It is important to be cautious when getting the chickenpox vaccine. You must understand the physical condition of the person being vaccinated and whether he or she is suitable for the vaccine. The vaccinee should also pay attention to its side effects and related contraindications. Only in this way can the chickenpox vaccine truly achieve its effectiveness, people's research will not be in vain, the disease can be prevented, and people will be less harmed by the disease.
