Navigating the evolving landscape of Covid-19: Insights on immunity, school openings, variants, and fall preparations

As Covid-19 infections rise again, experts say the risk of severe outcomes or long Covid is lower now due to prior immunity from vaccination or infection. However, it is still more dangerous than the flu, and there are still uncertainties about the virus. Immune function naturally declines with age, and certain medications or health conditions can suppress it. Vaccines are crucial for those with compromised immune systems, but some may benefit from preventive shots containing Covid-fighting antibodies. Variants like BA.2.86 highlight the need for ongoing vaccine updates. While the risk of long-term complications from Covid-19 appears to be decreasing, each infection adds to the chances of lasting damage.
