Chickenpox vaccine is required. The varicella vaccine is a self-funded, voluntary, Class II vaccine that protects against chickenpox caused by varicella-zoster virus infection. Chickenpox can be spread through direct contact and respiratory infections, and it is highly contagious. Therefore, chickenpox requires active prevention. If infected with chickenpox, although the prognosis is better, it still has an impact on your health. Chickenpox vaccination is effective in avoiding varicella zoster virus infection, so it is necessary to get vaccinated in time. Varicella vaccine can cause local redness and pain, itching, mild varicella-like rash, mild fever and other adverse reactions. Chickenpox vaccine should be contraindicated for people who are allergic to the vaccine components, those who suffer from serious illnesses, those with fever, and those with immunodeficiency. Before taking chickenpox vaccine, you need to consult a professional doctor for your specific situation and actively listen to the doctor’s advice.
