> But the thought was that it would greatly reduce the risk of spreading the disease, such that once a sufficient number of people were vaccinated herd immunity would kill off the virus and end the pandemic. We're now two years in with a 73% vaccination rate in the US (not counting those with natural immunity),
This was very clearly and openly discussed when the vaccines first came out: vaccines would help reduce spread and with a high enough rate that would end the pandemic but that we’d need relatively high vaccination rates to stop something which can spread this easily.
This was correct and the data suggests that it could have worked but we never seriously tried it. As of today, 61% of Americans have been vaccinated. That is far, far below the 90+% threshold used in those first messages — and that was before Delta and the Omicron delivered both higher spread and reduced effectiveness to make the problem harder.
The other thing to remember is that the pandemic ending doesn’t necessarily mean complete eradication. If, as appears to be the case, vaccination and medications significantly reduce the risk of serious illness and/or long COVID, that will probably be enough to get it down to the level of, say, influenza.
