People with health conditions that make them moderately or severely immunocompromised may get a fourth mRNA Covid-19 shot, according to updated CDC guidelines.
The CDC authorized a third dose for certain immunocompromised people 18 and older in August. It said a third dose, rather than a booster -- the CDC makes a distinction between the two -- was necessary because the immunocompromised may not have had a complete immune response from the first two doses.

As President Donald Trump is warming to the idea of using US military assets to strike Iranian nuclear facilities, officials and experts have suggested the US’ 30,000-pound “bunker buster” bomb is the only weapon capable of destroying the Fordow Fuel Enrichment plant, a facility thought to be to key Tehran’s nuclear program, which is carved into a mountain and extends deep underground.
