I'm having my booster on Monday and I've been told I have to let them know the day before whether I would like Pfizer or Moderna. My initial 2 doses were Pfizer. I've had a look at the government advice (I'm in Aus) but it doesn't recommend one over the other. The Pharmacist I spoke with recommended Moderna as they think it may be slightly more effective against Omicron.
Does anyone know of any studies which has shown which is best - same type vaccines or a combination? I'm breastfeeding if that has any significance.
If anyone has done Pfizer then Moderna, I would love to know if you had any different side effects?
