do not rapidly wane – we would need to follow their levels over time to know for certain – they may confer some or even substantial protection against aby booster shots. Initial vaccinations prompt our immune system to create antibodies to recognize and fight an invasive virus. The details of the antibody are carried by, which help keep watch for and sound the alarm if the virus reappears, quickly producing more of the specific antibodies to defend against it.
There was some concern this would occur with COVID-19 vaccines, too. So, using a mouse model and human volunteers who had contractedgrows stronger, which is a sign of positive imprinting. In both humans and mice, rather than seeing antibodies specific to any one variant, the researchers found the majority of the antibodies reacted to both tested COVID-19 strains – the original and omicron.
"At the start of the COVID-19 pandemic, the world population was immunologically naïve, which is part of the reason the virus was able to spread so fast and do so much damage,"Diamond."We do not know for certain whether getting an updated COVID-19 vaccine every year would protect people against emerging coronaviruses, but it's plausible."
