Question about first dose of vaccine and ‘short term protection’

[MrsDontDoMuch]

Hi, I’m going for my first jab tomorrow and was wondering something. My letter states the first dose gives ‘high levels of short term protection after 2-3 weeks’. So the efficacy kicks in after 2-3 weeks, but does anyone know what is meant by short term protection?
Does it mean until the second dose is administered 3 months later? Or would short term protection mean longer than a few months?
Many thanks

They don’t know. The trials were done based on two doses. One dose may have been more than enough but they were being cautious & we see in other vaccines that a later booster is helpful for longer term protection. For example, kids get MMR doses 2 years apart.

So we literally don’t know how long one shot might last. It might easily protect for a year. It might not. We do not have that data.

Ok thank you for replying
