Look at how the media is pushing the vaccine so hard and not reporting the side effects or deaths from the vaccine. They say they don't want to report on the side effects because it will discourage people from getting the vaccine but shouldn't we make up our own minds with all available information? It is looking like there will be more deaths from the vaccine than COVID by the time this is done.
It's being pushed because it um...works. Vaccines are like that, they have made diseases like whooping cough and measles and rubella and other nightmares a fading memory. They made tetanus into something that is like "what?" instead of a pretty common death sentence. They make shit work, and they do work. Death rates from Coivid have fallen like a rock with vaccination (ok, and getting rid of those stupid Trump death rallies) in place.
Don't compare this vaccine to the vaccines for whopping cough, measles, rubella and other nightmares because it is not the same. This is not your father's vaccine. This new mRNA vaccine does not provide sterilizing immunity against SARS-COV2 virus. Sterilizing immunity means you don't carry the virus and you can't transmit the virus. The vaccines for the disease you mention (and other nightmares) were different animals. This new vaccine will give partial immunity and will likely slow the spread but it doesn't guarantee immunity.
Fully vaccinated people are getting the virus. It would seem to follow that if they can still get it, they can still transmit it but we won't know until it happens and I believe it will.
