Nowadays, children are usually not vaccinated against smallpox.
Smallpox is an infectious disease that was eradicated in 1980 when the World Health Organization officially declared that smallpox had been completely eliminated, and since then China has announced that smallpox vaccinations have been phased out, so nowadays children are generally not vaccinated against smallpox.
Smallpox is a virulent infectious disease caused by the smallpox virus, and humans are the only host of the virus. Smallpox virus invades the human body through the mucous membrane of the respiratory tract through droplets produced by the breathing and coughing of smallpox patients; it can also be transmitted through direct contact with the skin lesions and clothes of patients.
Smallpox vaccine is the most effective way to prevent and control smallpox, which is often made by attenuating cowpox virus. Smallpox vaccine can prevent smallpox by stimulating the body’s immunity.
Nowadays, children usually do not need to receive smallpox vaccine, they should follow the doctor’s advice to receive other vaccines regularly. The main purpose of vaccination is to prevent other infectious diseases, which is helpful to the health of the body.
