Trust me, you don’t want a case of shingles. Been there done that last spring. It is a two shot vaccine about a month apart if i remember right - Shingrex is the name.
current pneumonia vaccine is also two dose, about 6 months apart.
Ask your dr ahead of your visit about getting the Northern hemisphere’s flu vaccine . You probably want it anyway, since you will be flying. I think the northern version’s selection of strains depends on what has happened in Australia and South America 6 months ahead. You will want the high potency version due to age. I get mine next week.
