> There are some serious evidence to back this up. A study done around early summer found that only about 50% of those that have taken two doses had any detectable traces of a defense, which was one of the reason that a third dose had to be added. By winter we don't know how effective the 2 dose or 3 dose will be. One study, going against countless others showing that the vaccines are highly effective. The readily available data speaks for itself. Highly vaccinated populations are experiencing much slower transmission and hospitalization rates than their poorly vaccinated counterparts. Also, we didn't start with one dose. Both mRNA vaccines were two-dose regimens from the day they started clinical trials last summer.

We don't have countless studies on how effective the vaccines over a longer period of time, and especially for those with two doses. Most seems to been done around 3 months, through most conclusions is based on simulations from observation data gathered by other vaccines such as smallpox, measles, mumps, and rubella. The observed half-life of neutralizing titers was 65 days for mRNA vaccines. The evidence will be found in the future when we have more data. Most expectation is that while the protection will be significant lower but that there might be some longer term benefits. Highly vaccinated populations that has taken the vaccine in the last 3-4 months are going to be currently more protected than those that aren't, but that doesn't say much if we need a new vaccination this winter, next summer or the year after that. It would be interesting to see a study done on those early groups of people that received the last dose of vaccine in 2020 during the summer and see how much protection that they still have now this fall in 2021. Got any links to such studies?
