"Co-administering Covid-19 and flu vaccines: Weighing the scientific evidence"
The US Centers for Disease Control and Prevention (CDC) says it is safe to get both the Covid-19 and flu vaccines at the same time, although a recent study found a slightly increased risk of stroke for seniors who received both shots simultaneously. However, other studies have not found the same risk, and the CDC and US Food and Drug Administration (FDA) have not changed their vaccine recommendations. Getting both shots together may increase the likelihood of temporary reactions such as fatigue, headache, and muscle pain. Some studies suggest that co-administration of the vaccines may lead to higher antibody responses, but more research is needed to confirm these findings. Ultimately, the decision to get both shots together or separately depends on personal preference, but health experts recommend getting vaccinated as soon as possible.
