At present, there are three types of new crown vaccines in China, namely, adenovirus vector vaccine, inactivated vaccine, and recombinant subunit vaccine, all of which are not harmful to human beings in the process of vaccination.
The new crown vaccine has already been mass inoculated in the population, and has more clinical use data, and there is no obvious harm to the human body in the process of inoculation. A small number of people have some adverse reactions during the vaccination process, such as fever, headache, muscle aches, pain at the vaccination site, etc. Most of these symptoms are mild and can return to normal in about 1~3 days.
The new crown vaccine has a better protective effect against the new crown virus, and can reduce the incidence of serious illness and mortality, so after ruling out the contraindications of the new crown vaccine, it should be inoculated in a timely manner.
