Very much so. They're all less effective against Delta though, still preventing a huge percentage of serious cases, but not preventing as much spread.The next vaccine race is on to tweak vaccines for the delta strain, which will be given as boosters. I'm hoping that a non mRNA vaccine gets in first, so that people who are opposed to vaccines don't have the new technology angle to hang their hats on. Although this time Scomo has backed Pfizer mRNA, which is why he just ordered 80 million doses.
Hopefully we eventually get a new mutation of a more infectious but less dangerous strain of covid, which is believed to have happened with a lot of viruses.
