The US Centers for Disease Control and Prevention (CDC) first spoke out in a detailed scientific report, The Washington Post reports.. After examining dozens of scientific studies and its own unpublished data, the American regulator found that both infection-induced and vaccine-induced immunity persists for at least six months, but vaccines provide more reliable protection and give a huge increase in antibodies for previously infected people..

The report also notes that there is no FDA-approved test that would allow doctors and the public to reliably measure a person's protection from disease.. And while a higher level of neutralizing antibodies usually indicates better protection, scientists do not know exactly what level of antibodies will protect a person..
