I’m a big fan of the nasal spray flu immunization; not quite as effective as an injection, but you can mail order it, and a nasal spray administered by mom or dad at home is a lot more pleasant than an injection. It also tends to mean less time sick each year.
dont forget HEPATITIS b VACCINE, the major causes of liver damage, cirrhosis and liver cancer. that one time i had the flu in 2018, it was insane, the symptoms were more intense than COVID that i caught this sept.
