All data is pointing to the original strain used in the vaccine is doing nothing to delta strain. And by the time they had a delta vaccine there would already be a new strain to worry about. It’s time to find a better way. Almost everyone who has been vaccinated that I’ve seen on social media are now terrified because they can’t get their “booster” because they know they have zero protection now due to how many months out it’s been since their 2nd dose.
