Guess you're smarter than these Mayo Clinic researchers..newsnetwork.mayoclinic.org Researchers Clarify Why Measles Doesn’t Evolve to Escape Immunity Mayo Clinic Staff March 30, 2021 Unlike SARS-CoV-2, which mutated into new strains in its first year as a human disease-causing virus, measles virus does not mutate in a comparable way. A person who is fully vaccinated against the measles virus will usually be protected for life. Now, with a Cell Reports Medicine publication, Mayo Clinic scientists think they know why measles doesn't escape control of the immune system... science.org Was smallpox a widespread mild disease? Smallpox—caused by variola virus (VARV), a poxvirus—was one of the most virulent diseases known to humans. The year 2020 commemorates the 40th anniversary of smallpox eradication, the first human disease eradicated after a global vaccination campaign led by the World Health Organization (WHO). (It didn't mutate every year and require a booster) npr.org Vaccine derived Polio There have been 21 cases of vaccine-derived polio this year. It has become fairly common each year for there to be one or two small outbreaks of vaccine-derived polio. These outbreaks tend to happen in conflict zones where health care systems have collapsed. "These outbreaks are occurring only in very rare cases and only in places where children are not immunized," says Zaffran. The regular polio vaccine protects children from vaccine-derived strains of the virus just as it protects them from regular polio. Vaccine-derived outbreaks, he says, "occur where there are large pockets of unimmunized children, pockets sufficiently large to allow for the circulation of the virus."
