On the morning of April 24, at the 2021 Frontiers Forum of Medical Science of the Chinese Academy of Engineering held in Guangzhou, Academician Zhong Nanshan gave an online report. He pointed out that he is currently working hard to develop a vaccine against mutant strains of the new coronavirus.

When talking about the precise prevention of the new crown epidemic, Zhong Nanshan said that the main contradiction we currently encounter is the mutation of the new crown virus. The mutant strains currently appearing are from the United Kingdom, Brazil, Nigeria, South Africa and other places. Now it seems that for the b1351 mutant strain in South Africa, we use a whole virus inactivated vaccine, which is the most commonly used vaccine of Kexinghe Sinopharm in China, and the protection rate against this mutant strain has been reduced. Now we are working hard to develop vaccines against mutant strains.

Academician Zhong Nanshan introduced that there are currently nearly 50 vaccines in the development process in China, and more than 200 vaccines are being developed in the world.

IT Home learned that the current national vaccination work is progressing smoothly. Up to now, my country's new crown vaccination has exceeded 200 million doses.

Ubuntu 近日正式发布了 21.04 版本，该版本采用了 Linux 5.11 稳定版内核，同时内置了微软 Active Directory 集成、用于 Flutter 应用开发的 SDK，以及默认启用 Wayland 替换了已有 36 年历史的 X Window System。

21.04 版本并非长期稳定版，将于 2022 年 1 月结束支持。该版本进行了一系列常规更新，GCC 更新到了 10.3.0，Python 更新到了 3.9.4，同时也提供了 OpenJDK 16（但不可用于包构建）。
