Can you still get chickenpox after receiving the chickenpox vaccine?

Generally speaking, receiving the varicella vaccine refers to getting vaccinated against chickenpox. Whether one can still develop chickenpox after vaccination depends on specific circumstances. If the immunization is successful, one generally will not contract chickenpox; however, if the vaccine fails to elicit a sufficiently strong immune response, it is still possible to get chickenpox. If any discomfort occurs, please seek medical attention promptly and undergo symptomatic treatment under the guidance of a qualified physician. A detailed explanation is as follows:

The varicella vaccine contains a live attenuated virus, which, when injected, stimulates the body to develop immunity against the varicella virus. Most people produce sufficient antibodies after vaccination to resist infection by the varicella virus. Therefore, exposure to a large amount of the virus shortly after vaccination generally does not lead to infection or results in only mild symptoms. In such cases, the vaccine has exerted its intended protective effect.

Individual immune responses vary. Some people may not develop a sufficiently strong immune response after vaccination, and thus may not be fully protected against infection by the varicella virus. In such cases, they may develop chickenpox. Additionally, over time, the protection provided by the vaccine may gradually wane. If exposed to a large amount of the virus a long time after vaccination, and if antibody levels are insufficient to resist the virus, infection may occur.

It is recommended to follow the prescribed vaccination schedule for the varicella vaccine and maintain good personal hygiene habits and a clean living environment in daily life to further reduce the risk of contracting chickenpox.
