Taiwan has 60 new cases of new crown confirmed, the new crown vaccine needs to be given the fourth dose? Chen Shizhong said so

The Taiwan region today reported 60 new confirmed cases of new coronary pneumonia, namely 11 local cases and 49 cases of overseas immigration, of which 23 cases were positive for flight landing, and there were no new deaths in the confirmed cases. Chen Shizhong, commander of the "command center" of Taiwan's epidemic epidemic, pointed out that there were 1483 people in overseas cases yesterday, 23 people were positive, with a positive rate of 1.55%, and today six flights were tested, with a positive rate of 2.34%. According to the "command center", the new local cases today are 4 males and 7 females, ranging from 5 to 60 years old.

In addition, the "command center" today announced the latest viral gene sequencing results for two cluster cases. Luo Yijun, deputy head of the medical response group of the "command center," said that the latest analysis found that the current infection chain in the north is mainly based on the infection chain developed by Taoyuan Airport, Qiandu Shabu-Shabu, Xidi Restaurant, and Yaxu Computer Factory, and the southern ones seem to be a follow-up extension of the infection chain of Kaohsiung Port.

According to Taiwan media reports, the "command center" has slowly deregulated epidemic prevention and control, which may be related to the low coverage rate of the third dose of vaccine. Chen Shizhong said that the new crown vaccine was "good" yesterday, with a total of 355,968 doses, of which the coverage rate of the first dose was 82.24%, the second dose was 75.50%, the basic booster was 0.76%, and the supplement was 28.56%. The coverage rate of limping additives reached 50% in early March.

The third dose in Taiwan is divided into "basic strengthening agent" and "supplementary agent". The "supplement" is aimed at the general public, that is, 2 doses of the base dose followed by one dose of the vaccine, of which Modena is given half a dose and the other labels are full dose. "Basal booster" is given to people with immunodeficiency and immunocompromisedness, the basic booster only needs to be separated from the second dose of vaccine by 28 days, and the supplement can be given after 5 months after completing the basic booster.

The NEW CROWN vaccine for children under 5 years of age developed by Pfizer in the United States and BNT in Germany is rumored to be postponed to April before submitting an audit to the US Food and Drug Administration (FDA). Chen Shizhong said that this may be a lack of clinical trial cases, more cautious about children's vaccines, and there is no progress on the island at present.

As for the United States study, the United States found that after four months of the third dose of vaccination, the antibodies in the body declined, and the fourth dose was needed. Chen Shizhong said that the island only began to administer the third dose of vaccine in early January this year, so far the time is relatively short, there is no urgency to administer the fourth dose of vaccine, if there is a need to administer, the "command center" procurement volume is enough for everyone to use.
