Girls, who had Pentaxim vaccinations for their kids in our age group, did you have any blood tests done after? How did you all handle it? We were told that blood tests aren't necessary if the child is feeling well, just come and get them done ?‍♀️ Sister also says you'll be overdoing it by poking the kid again, even though she's big now, you can do without blood tests, so I'm thinking about how to proceed in this situation.
