Introduction

The varicella vaccine is administered in two doses. The varicella vaccine is used to prevent varicella (chickenpox) infection. Varicella is an acute infectious disease caused by the varicella-zoster virus, which may lead to symptoms such as generalized red maculopapular rash, vesicles, fever, and other discomforts. Vaccination stimulates the body's immune system to produce antibodies that help fight the varicella-zoster virus.

Generally, the chickenpox vaccine requires two doses. The detailed explanation is as follows:

The chickenpox vaccine is designed to prevent infection from the varicella-zoster virus. Chickenpox is an acute infectious disease caused by the varicella-zoster virus, and patients may experience systemic symptoms such as red maculopapular rashes, blisters, fever, and other discomforts. Vaccination activates the body's immune system, prompting it to produce antibodies that can fight against the varicella-zoster virus. Typically, a single dose of the chickenpox vaccine does not generate sufficient antibody levels. Two doses are usually required to establish immunological memory and produce adequate antibodies to effectively prevent varicella-zoster virus infection. Therefore, two doses of the chickenpox vaccine are necessary.

If you plan to get vaccinated, it is recommended to visit a reputable hospital to avoid potential adverse effects.

What kind of cut or injury requires a tetanus shot?

There is no such thing as "only getting a tetanus shot if injured by a specific object." A tetanus vaccine or tetanus antitoxin injection is needed when wounds are deep and dirty, from animal bites or scratches, extensive and deep burns, open fractures or wounds with foreign objects, or when surgical wounds are contaminated, in order to prevent infection. If the wound becomes red, swollen, increasingly painful, or if systemic discomfort occurs, prompt medical attention is recommended.

Do you need tetanus shot after cutting your fingernail?

In general, whether a tetanus shot is needed after cutting a fingernail depends on the wound condition and immunization history. A tetanus shot should be administered promptly if the wound is deep, heavily contaminated, or if the person has not received a tetanus vaccine in the past 5–10 years. If the wound is shallow, clean, and the individual has been vaccinated within the past 5 years, a tetanus shot is usually unnecessary. Regardless of whether a tetanus shot is given, proper care should be taken after a fingernail injury.

What tests are needed before receiving the quadrivalent HPV vaccine?

Examinations generally required before receiving the quadrivalent HPV vaccine may include HPV virus testing, cervical cytology examination, routine blood test, coagulation function test, and screening for infectious diseases. These tests help determine whether there is an existing HPV infection, particularly the high-risk types (types 16 and 18) and low-risk types (types 6 and 11) covered by the quadrivalent vaccine, thereby clarifying the individual's infection status prior to vaccination.

What dietary precautions should be taken before and after receiving the HPV vaccine (Gardasil 9)?

Before receiving the 9-valent HPV vaccine, dietary precautions generally include avoiding alcohol, reducing intake of spicy and stimulating foods, avoiding vaccination on an empty stomach, minimizing consumption of allergenic foods, and maintaining a light, balanced diet. After vaccination, dietary considerations typically involve continuing to avoid alcohol, avoiding foods that may加重 gastrointestinal burden, increasing intake of high-quality protein, consuming more fresh vegetables and fruits, and refraining from drinking irritating beverages.

Can I eat lamb after receiving the HPV 9-valent vaccine?

You may consume a small amount if there are no post-vaccination discomforts such as fever, redness, swelling, or pain at the injection site, and if you normally do not experience allergic reactions, "heatiness," or gastrointestinal issues after eating lamb. Lamb contains high-quality protein; consuming it in moderation can help nourish the body and support immune function. In such cases, opt for light cooking methods (e.g., clear stewing) and avoid excessive consumption to prevent added strain on the body.

Can everyone get tetanus?

Cases in which tetanus will not occur are typically those with superficial, clean wounds that have been promptly and properly treated—such as rinsing with water and disinfection—and in which the individual has sufficient antibody levels (for example, having received the tetanus vaccine and still being within the protective period). In such cases, Clostridium tetani bacteria are unlikely to multiply or cause infection, the body can resist bacterial invasion, and no clinical symptoms of disease will appear.

Do you need a tetanus shot if you get pricked by a skewer?

If punctured by a skewer, shallow and clean wounds generally do not require tetanus vaccination. However, for deep wounds, contaminated or rusty skewers, or individuals with unknown immunization history, it is recommended to receive a tetanus vaccine or antitoxin promptly. If the wound continues bleeding, or shows signs of redness, swelling, or pus formation, immediate medical attention is advised. From a wound perspective, if the skewer is clean and causes only superficial abrasions with minimal bleeding.

What happens if you don't get a tetanus shot?

Failure to receive a tetanus shot may lead to tetanus infection, muscle rigidity and spasms, difficulty breathing or suffocation, organ dysfunction, and increased risk of death—especially when the wound is deep and contaminated. Prevention should be taken seriously. If the wound is heavily contaminated and the tetanus vaccine has not been administered, immediate medical attention is recommended upon experiencing symptoms such as weakness or muscle stiffness.
