Researchers develop more broadly protective coronavirus vaccine

Scientists have been searching for the optimal coronavirus vaccine since the COVID-19 pandemic started. The mRNA vaccines developed through the federal government's "Operation Warp Speed" program were a massive innovation; however, annually updating those boosters for specific SARS-CoV-2 variants is inefficient for scientists and patients.

SARS-CoV-2 is just one member of the Sarbecovirus (SARS Betacoronavirus) subfamily (others include SARS-CoV-1, which caused the 2002 SARS outbreak, as well as other viruses circulating in bats that could cause future pandemics).

Recent studies suggest staying up-to-date on COVID shots helps protect high-risk groups from severe illness

Thu, 2024-03-28 10:06 — mike kraft

Do you need a spring COVID-19 vaccine? Research backs extra round for high-risk groups | CBC News Various Canadian provinces are rolling out spring COVID-19 vaccination campaigns, allowing higher-risk individuals to get an extra dose. CBC

New guidelines suggest certain high-risk groups could benefit from having another dose of a COVID-19 vaccine this spring — and more frequent shots in general — while the broader population could be entering once-a-year territory, much like an annual flu shot.

Medical experts told CBC News that falling behind on the latest shots can come with health risks, particularly for individuals who are older or immunocompromised.
