At first researchers believed that recovering from COVID-19 meant the chances of getting the virus again so soon were low. Scientists thought we were protected for at least six months after the initial infection. This as it turns out is not true. You can be er-infected much sooner. The much raster re-infections are due to relaxed safety precautions such as masking and social distancing, as well as declining antibody levels and additional viral mutations, which can result in immune escape by omicron sub-variants.
Re-infections are common. The antibodies you generate in the face of one infection don’t necessarily protect you against other sub-variants for long.
