European Drug Administration: there is not enough evidence to support the second dose of covid-19 vaccine booster injection

The European Drug Administration said on the 3rd that there was not enough evidence to prove that the second dose of covid-19 vaccine booster should be vaccinated, but stressed again the importance of the first dose of booster. Mark Cavalieri, head of the vaccine Department of the European drug administration, said at a press conference on the same day that the current clinical trials and other evidence are not enough to support their suggestion that people should be vaccinated with a second dose of booster injection. However, he stressed that it is very important to continue to promote vaccination, including the first dose of booster injection. The data show that the protective effect of booster injection is very high.
