How far apart should I space for Whoping cough vaccine and c19 Covid 4th booster shot?Week 20th now.

Do have your flu vaccine/cough vaccine first since you are pregnant. 4th booster can wait later period. I have enquire before with doctor during previous consultation and follow up. As long as we have 2 shots + 1 booster shot for C19 then we are fine to take 4th shot later.
