Things we know: the Delta variant of COVID has broken through the vaccine in some cases, the vaccine helps if you get infected, unvaccinated people fuel the spread of the virus, and now, booster shots offer more protection. Israel released research that compared 149,144 patients who received a third dose of the Pfizer COVID vaccine to 675,630 patients who only had two doses. The groups were of similar ages, all over the age of 60. Why study this? Because Israel is showing more breakthrough infections in people having only two doses, and people over the age of 60 are particularly vulnerable to this virus.
