A few days ago, Gao Fu, a member of the National Committee of the Chinese People's Political Consultative Conference and director of the Chinese Center for Disease Control and Prevention, said in an interview with a reporter from China News Agency, "The protein vaccine we developed itself recommends three injections. Everyone didn't understand it at first, but its basic principle tells us. , one shot may not work." Gao Fu said that the inactivated vaccine has been given two shots, and now he proposes sequential immunization with heterologous vaccination.

Do I need to take the fourth and fifth needles after the booster needles?

This question is still a scientific question and will take time to answer.

Gao Fu said that the future vaccination strategy of the new crown vaccine will be comprehensively judged according to the characteristics of the new crown virus, the prevalence of the disease, and the characteristics of the vaccine.
