Hello. We have three doses of DTP scheduled this time, I'm very nervous because before New Year they got sick, had a high fever. Now everything is fine. To calm down, I took blood tests and vitamin D. Everything is fine. But we had a diabetogenic on the cheeks, so the vaccination was postponed until it passes. And now I'm going for the vaccination, and they advise to give Finistol before and a couple of days after. Has anyone done this? Before, Finistol wasn't taken, and before vaccinations, nothing was done. Only after the second DTP did we have a fever for one day. And now even teeth start, in general, everything is a mess.
