It is also not completely fake information, articles and statistics about reinfection and death because vaccinations are still real, explaining this situation is that each person's body will react differently, the body of many people will reject the antibody, some have other diseases in the body combined with vaccination, it has promoted the disease condition to become more serious. Maybe some people are malicious when releasing controversial information to create confusion, but in fact, vaccination does not give an absolute calculation, there is still a fairly small error.
Each and every medication has side effects. And the vaccines for COVID 19 are no exception to this. Even the most effective vaccines, such as Pfizer and Moderna have side effects, although in healthy people without comorbidities it never progress to serious complications. Pfizer has reported serious adverse effects at 0.002%-0.005%. The only serious complication I heave heard with the Pfizer vaccine is a study from Israel, which claimed that causes an increase in cases of myocarditis, especially for those who are aged above 80.
