Does this mean that a one-shot vaccine like Johnson & Johnson's is inherently less effective?
- robbrown451 6y agoI suspect that it is. There may be some reason it is good enough with a single shot, but the others aren't, but still... I didn't want J&J, not because I think it is a worse vaccine, but because it is currently only a single shot.
- suyash 6y agoI think it only protects about 60-70%
- tgsovlerkhgsel 6y agoIs there any evidence one shot of J&J protects better than one shot of Moderna/Biontech, or is the main difference that the companies chose different strategies for their studies/marketing? (Moderna/Biontech hoping to achieve better results and 2x the doses sold, J&J hoping to be done with the studies 3-4 weeks earlier and having a marketing advantage because it only requires one shot)
- hammock 6y agoJ&j could have been formulated as 2-dose, but they didn't test it that way, because the type of vaccine it is is well tested already to have reasonable effectiveness with a single dose. No rna jab had never passed phase iii before, so they hedged their bets and tested a 1/2 + 1 formula, knowing that it had higher likelihood to succeed testing.
