Are you immune to COVID? If you've had it before, are you really safe? A lot of people are wondering about this right now. The answer is not clear-cut. There have been a few cases of people getting the virus again after they thought they were immune. So, what do you need to know about COVID immunity? Keep reading to find out!
What is natural immunity?
Your natural immune system protects you from germs after they enter your body.
Immunity varies from person to person and germ to germ..
For example, people who have had measles are not likely to get it again, but this is not the case for every disease. A mild case of an illness may not result in strong natural immunity. New studies show that natural immunity to the coronavirus weakens (wanes) over time, and does so faster than immunity provided by COVID-19 vaccination.
What is vaccine-induced immunity for COVID?
Vaccine-induced immunity is what we get by being fully vaccinated with an approved or authorized COVID-19 vaccine. Research indicates that the protection from the vaccines may wane over time so additional doses (boosters) are now authorized for certain populations. These boosters can extend the powerful protection offered by the COVID-19 vaccines.
So if You've Had COVID Are You Immune?
COVID-19 affects people in different ways and has distinct strains. COVID-19 also comes in many varieties. Experts are unsure if we become immune to COVID-19 after infection. And, if we do have immunity, how long it will last is a mystery. Re-infections have been documented. They were induced by several types
Although coronaviruses have been present for a long time, researchers in 2013 discovered that they elicit some immunity. Coronavirus infections that cause the common cold last up to a year and appear to provide immunity. Our bodies also contain antibodies against SARS' virus for up to 4 years after infection.
The majority of those who have recovered from COVID-19 have anti-viral antibodies. There is no proof that having these antibodies will protect them against the virus if they are exposed to it again.
The National Institute of Allergy and Infectious Diseases (NIAID) and National Cancer Institute (NCI) studied a group of people who had recovered from COVID-19 and found significant immunity responses in the majority of those participating. While their levels remained fairly stable over time, they did decline modestly at 6 to 8 months after infection
