We’ve been sharing the planet with SARS-CoV-2 for more than three years now, but the science and recommendations for how to best protect against the virus and its variants are still constantly evolving.
In the latest major update to those recommendations, the World Health Organization (WHO)’s Strategic Advisory Group of Experts on Immunization (SAGE) said last week it no longer “routinely recommends” follow-up COVID-19 boosters for people with a medium or low risk of developing severe illness from the virus. Canadian health officials are, for the most part, echoing that message.
“Updated to reflect that much of the population is either vaccinated or previously infected with COVID-19, or both, the revised roadmap re-emphasizes the importance of vaccinating those still at risk of severe disease,” SAGE chair Dr. Hanna Nohynek said in a media release issued March 28.
