The second booster injection of Conocino needs to be given 6 months after the first injection, but the specific local vaccination time should be consulted with the relevant authorities. According to the relevant vaccination requirements, the second booster injection of Consenol is usually administered after the completion of the first vaccination and after an interval of 6 months. Within 6 months, the antibody titer and quantity in the body of the vaccinated person are still high, so there is no need for booster vaccination, and vaccination after 6 months can strengthen the antibody titer and enhance the protective effect. However, due to factors such as insufficient vaccine production capacity and recurring regional epidemics, you need to consult with your local health and epidemic prevention department, such as the CDC, for the specific local vaccination schedule. Generally, the CDC will arrange the vaccination according to the guidelines.
