But isn't vaccine supposed to make the virus less severe? I've seen many of my relative or friend of a friend who caught the virus weeks after getting the vaccine. Most of them have less severe effect, some of them still have critical condition..

At this point if even vaccine is not effective, then we're not sure how to kick this virus ass anymore

I'm still pro to get vaccine btw, I'm getting it once I am eligible :/



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.


Yes, the vaccines are still very effective against severe disease. It is transmissibility that's changed dramatically.


That is exactly what the article says (25x less likely to have a severe case/die).

The point is the transmissability (as also recently published by the CDC). You yourself get a milder case if you're vaccinated and catch Delta. But you can now still transmit it to children that can't be vaccinated (and who potentially are in a risk group), friends that have a contra-indication to vaccination but are in a risk group etc.
