Got small wood splinter. Don't remember if I took Td while child. Took Td 10 years ago. I am 56, Do I need another shot. Palm is hurting. Any concerns?

Yes and No. Adults should receive tetanus boosters every 7-10 years and at least one of them should be a TDAP vaccine which includes a pertussis booster as well. That being said, it is unrelated to a wood splinter. There is no concern for tetanus infection from a wood splinter. These come from rusted metal. However if your hand is in pain, ensure that the splinter has been completely removed.
