If the proportion of vaccinated people in a community is below the herd immunity threshold, a contagious disease could continue to spread. Some people object to getting a COVID-19 vaccine because of religious objections, fears about the possible risks or skepticism about the benefits. Food and Drug Administration has approved two COVID-19 vaccines and given emergency use authorization to a handful of COVID-19 vaccines.īut reaching herd immunity through vaccination against COVID-19 will likely be difficult for many reasons. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems. Using the concept of herd immunity, vaccines have successfully controlled contagious diseases such as smallpox, polio, diphtheria, rubella and many others. Unlike the natural infection method, vaccines create immunity without causing illness or resulting complications. Herd immunity also can be reached when enough people have been vaccinated against a disease and have developed protective antibodies against future infection. The health care system could quickly become overwhelmed. Infection with the COVID-19 virus could lead to serious complications and millions of deaths, especially among older people and those who have existing health conditions. Because reinfection can cause severe medical complications, it's recommended that people who have already had COVID-19 get a COVID-19 vaccine.
However, even if you have antibodies, you could get COVID-19 again. It's estimated that getting COVID-19 results in a low risk of another infection with a similar variant for at least six months. There are some major problems with relying on community infection to create herd immunity to the virus that causes COVID-19: Some scientists call this hybrid immunity. Recent research also suggests that people who got COVID-19 in 2020 and then received mRNA vaccines produce very high levels of antibodies that are likely effective against current and, possibly, future variants. A recent study showed that unvaccinated people who already had COVID-19 are more than twice as likely as fully vaccinated people to be reinfected with COVID-19. In addition, COVID-19 vaccination might offer better protection than getting sick with COVID-19. It's estimated that getting COVID-19 and COVID-19 vaccination both result in a low risk of another infection with a similar variant for at least six months.īut because reinfection is possible and COVID-19 can cause severe medical complications, it's recommended that people who have already had COVID-19 get a COVID-19 vaccine.
