Breakthrough infections are the bane of the world of vaccines; no inoculation, regardless of its effectiveness, can ever stop all infections 100% of the time. The good news is that, when someone who is vaccinated gets a breakthrough infection, the symptoms are almost always much more mild.
Now a new study reinforces the good news about vaccines and breakthrough infections. According to an article published in the journal Clinical Infectious Diseases, fewer than 1 out of 1,000 people who were either vaccinated or had natural immunity required hospitalization if they suffered from a breakthrough infection. The rates of hospitalization between different groups was statistically insignificant: 6 out of every 10,000 vaccinated patients, 3 out of every 10,000 previously infected but unvaccinated people and 1 out of 10,000 among patients who were both previously infected and vaccinated.
