| 回覆中加入附件並不會使你增加積分,請使用主題方式發佈附件。 To make a vaccine, in old days it usually uses the attenuated or inactivated virus. With advances in immunology and biotechnology, a better choice would be the empty shell of the virus without its infectious nucleic acid inside the virus. Cross-linked coated protein that retain the antigenecity of the virus and can bind to the target cell would also work. |
