Many of the vaccines are effective against the delta, but they do not serve as a firewall to stop the spread of infection within a community.

As a simple example, imagine you have a community of 100 people. 1 person is infected, 98 are vaccinated, and 1 is uninfected and not vaccinated.

Ideally the 98 people who are vaccinated don’t contract the virus, and do not serve as vectors of spread for that one unvaccinated person. In essence, you make it so the one infected person has to come in contact with the unvaccinated person.

With delta, the 98 vaccinated people are astronomically less likely to die or become severely ill from covid; however, they still can contract and pass along the virus… Which can eventually make its way to the one unvaccinated person at the end of the chain.

So, vaccines are great. Vaccines work. These vaccines are awesome for how fast they were produced. But they aren’t able to serve as barriers of protection for the unvaccinated in a way other vaccines for other diseases.
