AstraZenica is piling on, their CEO previously saying they expect immunity from their vaccine to last a year. Article did not provide any explanation why they think it only lasts a year, but my guess is that this is merely more Doom Patrolling.
I don’t think the statement that they expect a year worth of immunity is a statement that they believe it to not last longer then a year. Big Pharma companies are limited in what they can claim and if you are registering a 1-year clinical trial then it makes sense to speak about your expectation of 1-year worth of immunity.
I think that’s reasonably chalked up as the work of Doom Patrolling even if it’s not specific to this pandemic. But I expect you’re right about the specific reasons for the one year duration.
