spoke to on offshore guy I work with in India who said the vaccine doesn't work against this delta variant. not sure how true this is.
Depends, as always, on how you define "work".
Does it work to prevent infection with the new variants? Depending on the vaccine it does appear to be a lot less effective.
Does it work to stop the spread of the virus, especially the new variants? Jury seems to be out on this. Having at least some people not catch the virus as a result of the vaccine would reduce spread, but limited impact is the impression I get.
Does it stop you getting sick if you do catch COVID? The answer appears to be no if you define getting sick as having any symptoms of COVID - ie: you would include people with mild to middling flu-like symptoms as having got sick.
Does it stop you from getting severely ill and dying as a result of catching COVID? I don't think we know enough yet but the signs are that those who are vaccinated are way less likely to become severely ill (requiring hospitalisation) or die from COVID, and this applies to all variants.
All up the vaccine is still looking like a success from this. If having the vaccine means you might get sick but are very unlikely to be severely ill or die then COVID getting loose in the community becomes a problem of similar magnitude to the flu which we know is loose in the community all the time.
Of course, the impact of vaccination is heavily reliant on the proportion of the population vaccinated, the more the better.
I figure some here who work in health care will know more and be able to correct me if any of the above is incorrect.
