Primary Omicron infection in unvaccinated individuals triggers weaker antibody responses with poor neutralization. Pre-Omicron variant exposure boosts robust humoral immunity and CD8 T cell responses in secondary infections, though antibodies decline by day 90. CD4 T cell levels and polyfunctionality remain comparable across groups up to D30, highlighting immune dynamics between primary/secondary Omicron infections.
Describe the visual content in natural language (e.g., 'A cyberpunk cat wearing neon goggles') and our AI models will create outputs. Complex prompts trigger multi-stage NLP parsing for enhanced accuracy.
Use our Prompt Bot - an AI-powered optimizer that suggests technical modifiers. Simply describe your ideas, desired changes ('more metallic texture'), then you will get optimized prompt variants.
