close to 30 vaccines have been rolled out, and there are more than 140 in clinical trials. Many more are in the pipeline, too…
overview of clinical trials and other studies on boosting and mixing vaccines.
a combination of waning immunity and variants has focused a lot of recent attention on boosters. Mixed vaccine schedules, on the other hand, have been critical ever since we’ve had a range of vaccines with uneven supply. Mixing vaccines isn’t only considered for logistical reasons, though. It can be done in hopes of improving immunity. The theory is that this could widen immune responses more than same-same vaccination, as vaccines are targeted at stimulating the immune system in different ways.
There are 3 major issues this post doesn’t address: vaccine outcomes specifically in people who have also been infected with the SARS-CoV-2 virus, outcomes in the under-18s, and adverse events after boosters and mixed schedules.
Major safety concerns in rollouts of boosters haven’t been reported
