Summary

Flu season expected to peak sooner in Nova Scotia this year.
Current flu vaccine offers less protection against dominant H3N2 strain.
Health officials urge increased precautions due to vaccine mismatch.

Nova Scotia's flu season is anticipated to arrive earlier than usual, with health officials like Dr. Robert Strang highlighting the potential strain on the healthcare system. The predominant influenza A (H3N2) strain is circulating, but the current vaccine provides a less-than-ideal match for this specific type. Despite this, the vaccine is still expected to offer some protection against severe outcomes.

This vaccine mismatch underscores the need for heightened public health measures. Dr. Strang advises individuals to continue practicing preventative actions such as wearing masks in crowded indoor areas, maintaining good hand hygiene, and isolating when feeling unwell. These steps are crucial given the historical association of H3N2 with more severe health consequences, particularly for children and older adults.

Beyond the flu, Nova Scotia is also monitoring COVID-19 and encouraging vaccinations for it, along with a free RSV vaccine program for seniors and children. Pregnant women are specifically encouraged to get vaccinated against the flu to protect themselves and their unborn children through passive immunity transfer.
