Some vaccines, such because the MMR vaccine (measles, mumps and rubella), can give lifelong coverage. Against this, the effectiveness of COVID vaccines starts to say no within the months afterwards.
Immunity doesn’t merely drop off a cliff. It’s a extra sluggish decline, with a standard relief of about 21% in coverage towards an infection and 10% towards serious illness within the six months after vaccination.
Even though the decline in immunity can also be extra pronounced within the aged and the ones with weakened immune methods, all age teams are affected. And any notable relief in immunity will supply alternatives for higher virus transmission, and in the end be mirrored in higher occurrence of significant sickness, hospitalisation and dying.
