None. Last April/May I already got two jabs and it's enough for me. Actually, I had opportunity to choose from these 4 vaccines and took Pfizer without thinking much. I just wanted to stay away from Astra Zeneca. Though, even without getting vaccinated, most likely that I would have light covid - I'm young and healthy person. In general, I got vaccinated just get covid passport.
But now, when omicron is spreading, vaccination is more or less pointless. For most people it have mild symptoms and vaccine don't give much protection from getting infected. Omicron is best vaccine now.
