"Based on what we know now, the most likely scenario is that the COVID-19 virus continues to evolve, but the severity of disease it causes reduces over time as immunity increases due to vaccination and infection," Director-General Tedros Adhanom Ghebreyesus said during a briefing.
In the WHO's rosier, best-case scenario, future variants would be "significantly less severe", protection from severe disease would be long-lasting, without the need for future boosting or significant changes to current vaccines. The report, Strategic Preparedness, Readiness and Response Plan, is the WHO's third, and will likely be its last, Tedros said.
Countries also must continue to do diagnostic testing for SARS-CoV-2, which helps identify individual cases and guide community-level decision making, and for tracking the virus evolution within animal populations, according to the WHO.
