Vaccine could be a dud?!?, page-5

I can't see the point of the vaccine
1- If you have had the vaccine, you can still be a carrier, so it doesn't protect anyone else
2- If you have the vaccine, you still have to wear a mask and comply with all restrictions
3- There are many strains, so not sure it will give immunity
4- Trials haven't been long term, so long term impacts are not known

I have never been an anti-vaxxer, and have had every vaccination known, so please don't pin that on me. I can't see the point of this one.
