The latest COVID-19 vaccines, updated to target the KP.2 variant, are now available following FDA approval, with CDC recommending vaccination for everyone aged 6 months and older. As respiratory virus season nears, the CDC also advises flu shots, which can be administered alongside COVID-19 vaccines. However, uninsured Americans face high costs for COVID-19 vaccines due to the expiration of federal funding, with doses priced up to $200. Pharmacies like Walgreens, CVS, and Weis Markets are rolling out the new vaccines, while Pfizer and Moderna may offer patient assistance programs with unclear eligibility. Research highlights that factors such as stress, exercise, and hormonal birth control may influence vaccine side effects, emphasizing the need for personalized health approaches.
