The Vaccine is not protection from Covid and those that are vaccinated and acting so carelessly are the reason it is spreading.
I don’t believe that people’s “careless” behavior has anything to do with it allegedly spreading.
Far more plausible explanations are that the vaccine just s8mply doesn’t work as advertised and the influx of disease carrying illegals who have not been quarantined nor vaccinated has more to do with it.
It would be interesting to see the demographic breakdown of these alleged cases. And I say alleged because it depends on what they are using to test for COVID. Are they still using the 90% false positive PCR test?
