Yeah the reading and logical comprehension of the results presented in the article are so bad here lol. The native strain has 100% mortality rate, so adding the omicron spike protein to the native strain actually reduced mortality.

Thank you for the link.

Omicron being less deadly seems correct based on what is presented in the article. The ancestral virus strain had 100% mortality. Ancestral virus + omicron spike protein had 80% mortality. Omicron strain had mild symptoms.
