Just got my booster. I had my 2nd Pfizer shot in March so it's almost 10 months. This time I opted for the Moderna because real world data shows the vaccine had held it's efficacy longer. I also feel Moderna was more honest in the last couple days, saying vaccines will be probably be less effective against B.1.1.529 Variant, while Pfizer announced their vaccine will protect against it. There's no way for them to know that and they are being very disingenuous.
