"Latest COVID-19 Booster Shot and Vaccine Updates: What You Need to Know"

The FDA has authorized updated versions of the Pfizer and Moderna mRNA vaccines as booster shots for Covid-19. The CDC recommends that everyone over six months old should get the booster, with certain exceptions for those who recently had Covid-19 or were recently boosted. The focus is on individuals at the highest risk for severe illness, including older adults, those with underlying health conditions, and the immune-compromised. While some experts argue for a more targeted approach, the agencies hope that the booster shots will help prevent serious illness and reduce the chances of long Covid. The immunity from the new shot is expected to last a few months, and health insurance will cover the cost for most Americans.
